AUGUST · WHERE TO GO · 14 TRIPS
An August vacation splits into two trips that share nothing but a page of the calendar. Fly to Upper Egypt and the afternoon reads 105.0°F, with 0.00 inches of rain for the entire month. Fly to Patagonia the same week and the high is 37.4°F, with 6.2 days wet enough to change a plan. That is a 68-degree spread between two ways of spending the same fortnight off work, and neither one is a mistake.
The fixed points this month are astronomical. On August 15, a trip to Iceland still gets 16 hours 28 minutes of daylight while Patagonia is down to 9 hours 58 minutes, so one itinerary books evenings and the other books mornings. The sea off Crete averages 82.0°F, warm enough that swimming rather than sightseeing becomes the shape of the day. The Atlantic hurricane season also runs through the whole month, so a Caribbean plan starts with the storm-risk read in our hurricane-season guide.

THE MONTH AT A GLANCE · AUGUST
August offers rain-proof northern coasts, desert heat that dictates your hours, tropical rain on half the days, and a southern winter running from 37°F to 63°F.
DRIEST: SAN DIEGO 0.01 IN · HOTTEST: UPPER EGYPT 105°F · WETTEST: COSTA RICA 16.5 DAYS · SOUTHERN WINTER: PATAGONIA 37°F · LONGEST DAYS: ICELAND
Go for: the dry-coast trips, San Diego at 0.01 inches and the Algarve at 0.2 rain days, when a whole family has to be kept happy for a week.
Think twice before: booking a walking-heavy itinerary in Upper Egypt or Crete, where 105.0°F and 88.0°F afternoons run the schedule for you.

Where is it driest in August? San Diego, the Algarve and Crete
Four trips on this list are close to rain-proof. San Diego records 0.01 inches across August, the Algarve 0.08, Lisbon 0.17 and Crete 0.21, all of them under a quarter inch for the month.
Heat and water separate them. Crete pairs 88.0°F afternoons with an 82.0°F sea, so the trip organizes itself around swimming. San Diego holds 77.3°F days over a 71.3°F ocean, and Portugal’s two coasts sit in between, with Atlantic water in the mid-60s that shortens most swims to a quick one.
San Diego
77°F days, 68°F nights · 0.0 rain days · 71°F sea · 13h 23m of daylight on Aug 15 · $$
This is the trip you book when nobody in the party can absorb a lost day. NOAA’s 1991-2020 normals give the city 0.01 inches of August rain and 0.0 days reaching even a tenth of an inch. Five nights (est.) covers the beaches, Balboa Park and a day out across the county, and the whole thing stays domestic: no passport, no connection, no jet lag from the West Coast.
Set that against Upper Egypt, where the same 0.00-inch month arrives at 105.0°F. San Diego delivers a comparable calendar 28 degrees cooler. The trade sits in the water: at 71.3°F the Pacific is a wading ocean rather than a floating one, and the 13h 23m day on August 15 does the rest of the work.
The Algarve
80°F days, 69°F nights · 0.2 rain days · 67°F sea · 13h 37m of daylight on Aug 15 · $$$
The Algarve is the seven-night (est.) version of the same idea, roughly eight hours from Newark to Lisbon (est.) plus a two-and-a-half-hour drive south. August brings 0.08 inches of rain over 0.2 days, and 69.0°F nights that keep dinner outdoors until late. The Atlantic is the catch at 66.8°F, and the bathing-season detail, beach by beach, sits in the Algarve in August.
Crete
88°F days, 73°F nights · 0.5 rain days · 82°F sea · 13h 32m of daylight on Aug 15 · $$$
Crete asks for ten nights (est.) and a European connection, and it repays them with the warmest swimming any of these Mediterranean trips can offer: an 82.0°F sea under 88.0°F afternoons, with 0.21 inches of rain for the month. The cost is company. We carry climate normals here rather than visitor counts, so treat August’s queues at the ferry docks and the Samaria trailhead as the known price of half a rain day.
Lisbon
80°F days, 65°F nights · 0.5 rain days · 66°F sea · 13h 43m of daylight on Aug 15 · $$
Two and a half hours up the road, Lisbon reads almost identically by day, 79.8°F against the Algarve’s 80.2°F, and sleeps four degrees cooler at 65.4°F. Three nights (est.) at the front of an Algarve week is the standard shape, with a 66.2°F sea at Costa da Caparica if the beach urge arrives early. The month, city by city, is in Lisbon in August and Portugal in August.
Is August too hot for Upper Egypt and the Southwest?
Heat decides the timetable on these three trips rather than the destination itself. Upper Egypt runs 105.0°F afternoons against Zion’s 85.3°F and Sedona’s 88.7°F, and each of them leaves a different set of usable hours in the day.
Upper Egypt
105°F days, 76°F nights · 0.0 rain days · 13h 04m of daylight on Aug 15 · $$
Nothing in these numbers is borderline. Luxor and Aswan post 105.0°F highs, 75.9°F lows and 0.00 inches of rain across August, with 0.0 days reaching a tenth of an inch. Weather never cancels a Nile trip in this month. It compresses it.
Karnak at opening and the Valley of the Kings before nine is the entire strategy, followed by a long indoor middle of the day and a felucca once the sun drops. Five nights (est.), most of them aboard a boat with shade and cold water, is the format that survives 105.0°F. Anyone who wants afternoons should move the identical itinerary to winter and lose nothing but the empty ticket line.
Zion
85°F days, 62°F nights · 1.2 rain days · 13h 37m of daylight on Aug 15 · $$
Zion in August is a dawn park. Highs of 85.3°F over 62.2°F nights make the first hours genuinely pleasant, and 0.47 inches of rain sounds negligible until you notice it lands on 1.2 days. Concentrated water on few days is the summer monsoon signature, and it is the reason to read the park’s own flash-flood outlook the morning you plan the Narrows. Fly into Las Vegas, drive about 2¾ hours (est.), and give the park three nights (est.).
Sedona
89°F days, 65°F nights · 2.9 rain days · 13h 29m of daylight on Aug 15 · $$
Sedona sits three degrees hotter than Zion at 88.7°F and takes more than twice the rain, 1.17 inches over 2.9 days. On a red-rock trip that means storm-watching from a terrace about as often as hiking through the middle of the day. Phoenix is the airport, roughly two hours away by car (est.), and two nights (est.) bolt neatly onto a Zion week.
Where does it rain most in August? Costa Rica, the Yucatán and Kyoto
Three trips here carry serious August rain, and the totals are not comparable to a damp week in Europe. Costa Rica takes 8.47 inches, the Yucatán 5.76 and Kyoto 5.44.
For planning days out, the count of wet days matters more than the totals. Costa Rica logs 16.5 days at a tenth of an inch or more, the Yucatán 14.8 and Kyoto 9.2. Measured against San Diego’s 0.0, those are vacations of a different design, built around mornings and covered fallbacks.
Costa Rica
86°F days, 73°F nights · 16.5 rain days · 86°F sea · 12h 30m of daylight on Aug 15 · $$
Guanacaste runs 85.7°F days over an 86.0°F ocean, with 8.47 inches spread across 16.5 wet days. That is more than one day in two. Against San Diego’s 0.01 inches, it is roughly 850 times the monthly total, and the two trips sit at opposite ends of what the phrase beach vacation can cover.
In practice the day takes a shape. Book the boat, the canopy tour and any long drive before noon, and keep the afternoon for lodges, hot springs and the sound of rain on a tin roof. Seven nights (est.) is the minimum that absorbs two washed-out afternoons without wrecking the trip, and Miami to Liberia is about three hours in the air (est.).
The Yucatán
86°F days, 79°F nights · 14.8 rain days · 87°F sea · 12h 52m of daylight on Aug 15 · $$
The number to watch on this coast is the night. Lows average 79.0°F, so the air never resets between 86.1°F afternoons, and 14.8 rain days land on top of that. The sea, at 87.1°F, is the warmest water here. Four hours from New York (est.) and five nights (est.) is the usual shape, with cenotes and Chichén Itzá as the rain plan and the storm calendar as the reason to buy a flexible fare.
Kyoto
88°F days, 74°F nights · 9.2 rain days · 13h 31m of daylight on Aug 15 · $$$
Kyoto is the hardest walking city on this list this month. Afternoons reach 87.8°F, nights hold at 73.8°F, and 5.44 inches fall over 9.2 days, often ending an outdoor plan within ten minutes. Mornings are the only reliably comfortable hours, so a five-night trip (est.) starts at Fushimi Inari before seven and saves the museums, the covered arcades and a slow lunch for the middle of the day. Osaka is roughly twelve hours from San Francisco (est.), plus a short train.
Where is it winter in August? Patagonia, Sydney and Cape Town
South of the equator, August closes the winter, and these three trips sit 25 degrees apart. Patagonia holds 37.4°F afternoons, Sydney 62.7°F and Cape Town 61.7°F, which turns one into an expedition and the other two into city weeks with a jacket.
Patagonia
37°F days, 30°F nights · 6.2 rain days · 9h 58m of daylight on Aug 15 · $$$
This is the coldest trip on the page and the shortest day, 9 hours 58 minutes on August 15. Long trekking circuits are out. What stays in is the winter version: the Perito Moreno walkways in low light, Fitz Roy under cloud, 2.05 inches of precipitation falling as snow at least as often as rain. Reaching El Calafate takes a Buenos Aires connection and the better part of a day; allow eight nights (est.) for the weather to give you two clear ones.
Sydney
63°F days, 49°F nights · 2.9 rain days · 64°F sea · 10h 54m of daylight on Aug 15 · $$$
Sydney ends the southern winter with the driest figures of the three: 1.48 inches over 2.9 rain days, and 62.7°F afternoons that suit the Bondi-to-Coogee walk better than any summer heat would. The water sits at 64.3°F, surfing temperature rather than swimming temperature for most visitors. Fifteen hours from Los Angeles (est.) argues for ten nights (est.) at a minimum.
Cape Town
62°F days, 49°F nights · 7.1 rain days · 58°F sea · 10h 55m of daylight on Aug 15 · $$$
Cape Town takes its rain in winter, and August sits inside it: 2.90 inches over 7.1 days, close to double Sydney’s total at the same latitude. Days still reach 61.7°F, warm enough for the winelands, the museums and Table Mountain whenever the cloud lifts off the table. A 57.7°F sea ends the beach conversation early. Roughly fifteen hours nonstop from New York (est.), and seven nights (est.) leaves room for the weather to move around you.
Is August a good time for Iceland?
One northern trip is built for this month. Iceland offers 56.3°F days and 47.1°F nights, with 11.4 rain days as the standing cost of driving the ring road at all.
Iceland
56°F days, 47°F nights · 11.4 rain days · 55°F sea · 16h 28m of daylight on Aug 15 · $$$
The month posts 4.11 inches over 11.4 days, so waterproofs belong on the back seat rather than in the case. Light is what buys those days back: 16 hours 28 minutes on August 15, enough to drive the south coast, walk out to a glacier tongue and still reach a village pool before closing. Reykjavík is about five and a half hours from New York (est.), and eight nights (est.) covers the loop without a forced march.
Darkness is the other August gift. A 16h 28m day leaves roughly seven and a half hours below the horizon, and by the last week of the month that becomes real night. A late-August trip can therefore end a sixteen-hour driving day with an aurora attempt, which no July itinerary can promise. The sea, for the record, averages 54.9°F, so the swimming happens in geothermal water.
August travel: crowds, storm season and heat by destination
Crowds are the constraint nobody prices in. European school holidays and Mediterranean beach weather land together this month, so Crete’s 0.5 rain days and the Algarve’s 0.2 come with company on every ferry, coast road and restaurant terrace. Portugal’s month, region by region, is laid out in Portugal in August, and the twelve-month comparison sits in the best-time guide.
Storm risk is geographic rather than general. The Atlantic season covers the Yucatán and the Caribbean right through August, so a flexible fare and a clear cancellation policy do more for the trip than watching the forecast the week you fly. Jamaica in August works the same month at island scale, hotel by hotel.
Heat is the constraint travelers underestimate on their own itinerary. At 105.0°F in Upper Egypt, 88.7°F in Sedona and 88.0°F on Crete, a plan has to hold up between eleven and four, when almost nothing outdoors does. The tiers here ($ to $$$) are relative August signals across these fourteen trips, not quotes: we hold no fare or room-rate data for the month, and the tiers track the school calendar more than the thermometer.
Where to go in August: San Diego, the Algarve or Crete
| Destination | Aug days | Rain days | Sea | From the US (est.) | Tier | Best for |
|---|---|---|---|---|---|---|
| San Diego | 77°F / 68°F | 0.0 | 71°F | domestic | $$ | A rain-proof family beach week |
| The Algarve | 80°F / 69°F | 0.2 | 67°F | ~8h to Lisbon + 2½h drive | $$$ | Dry coast, warm nights: our guide |
| Crete | 88°F / 73°F | 0.5 | 82°F | via European hub, 13h+ | $$$ | The warmest Mediterranean swimming |
| Lisbon | 80°F / 65°F | 0.5 | 66°F | ~6½h from JFK | $$ | City days before the coast: our guide |
| Upper Egypt | 105°F / 76°F | 0.0 | inland | via Cairo, 14h+ | $$ | Monuments at dawn, boat by day |
| Zion | 85°F / 62°F | 1.2 | inland | Las Vegas + 2¾h drive | $$ | Early-morning canyon hiking |
| Sedona | 89°F / 65°F | 2.9 | inland | Phoenix + 2h drive | $$ | Red rock under monsoon skies |
| Costa Rica | 86°F / 73°F | 16.5 | 86°F | ~3h from Miami | $$ | Green-season wildlife, morning plans |
| The Yucatán | 86°F / 79°F | 14.8 | 87°F | ~4h from JFK | $$ | Warm sea, cenotes as the rain plan |
| Kyoto | 88°F / 74°F | 9.2 | inland | ~12h to Osaka + train | $$$ | Temples at first light |
| Patagonia | 37°F / 30°F | 6.2 | inland | via Buenos Aires, most of a day | $$$ | Glaciers in winter light |
| Sydney | 63°F / 49°F | 2.9 | 64°F | ~15h from LAX | $$$ | Coastal walks at the end of winter |
| Cape Town | 62°F / 49°F | 7.1 | 58°F | ~15h from JFK | $$$ | Winelands and museums between fronts |
| Iceland | 56°F / 47°F | 11.4 | 55°F | ~5½h from JFK | $$$ | The ring road on sixteen-hour days |
Averages hide distribution. Costa Rica’s 16.5 wet days out of 31 do not spread themselves politely across a week, so a seven-night trip can catch four soaked afternoons or two. Cape Town’s 7.1 days arrive with a front rather than a shower, which is a different problem for a driving itinerary. And a mean stays a mean: Upper Egypt’s 105.0°F August contains plenty of afternoons above it, and that is what decides whether a Valley of the Kings morning ends at ten or at noon.
The last word
One booking here carries almost no weather risk: San Diego, at 0.01 inches and 0.0 wet days, with no passport and five nights a family can plan without a backup. Take it if August simply has to work. The far end of the swing is worth more, though. Patagonia gives you a 37.4°F afternoon, 9 hours 58 minutes of daylight, and the Buenos Aires connection on the way, where the city sits at a comfortable 60.2°F with 5.2 rain days of its own. Lose a day there on purpose.
