PUERTO PENASCO · FEBRUARY · SONORA
February in Puerto Penasco brings shirt-sleeve afternoons on the Sea of Cortez: an average high of 68.4°F, about 11 hours 08 minutes of daylight on the 15th, and measurable rain on only 1.4 days. The sea is another matter at 62.0°F, which turns most swims into quick dips.
Two neighboring months frame the choice. January runs 1.2 degrees cooler on the average high, and March adds 3.9 degrees plus a 65.0°F sea. Most U.S. visitors arrive by car through the Lukeville-Sonoyta crossing, so the dates you pick are also dates for a border drive.

THE MONTH AT A GLANCE · PUERTO PENASCO
February is a month for shore walks and long outdoor lunches at 68.4°F, with a 62.0°F sea that suits a quick dip and not a long swim.
HIGHS 68.4°F · LOWS 53.8°F · SEA 62.0°F · 1.4 RAIN DAYS
Go for: mild, dry days on the Sea of Cortez shore, layers-and-sunglasses weather, and a stay at Sandy Beach or Cholla Bay without heat to plan around.
Think twice before: counting on warm-water swimming (the sea is 62.0°F), or booking without reading the State Department’s Level 3 advisory for Sonora.

One item comes before the weather. The U.S. Department of State’s Mexico Travel Advisory, reissued May 29, 2026, lists the State of Sonora at Level 3, reconsider travel, due to terrorism and crime. We did not verify how the advisory treats Puerto Penasco itself, so read its Sonora section before you book anything non-refundable.
Puerto Penasco weather in February
| February normal (1991-2020) | Puerto Penasco |
|---|---|
| Average high | 68.4°F |
| Average low | 53.8°F |
| Precipitation | 0.53 inches |
| Days with 0.10 inch or more | 1.4 |
| Days with 1 inch or more | 0.0 |
| Sea surface (Open-Meteo Marine API, 2015-2024) | 62.0°F |
| Daylight on February 15 | 11 h 08 min |
Every figure here is a 1991-2020 normal from ERA5, the ECMWF model reanalysis served by Open-Meteo, computed for the grid cell over Puerto Penasco. No thermometer produced these numbers: none of the town’s three CONAGUA stations (Smn, Dge and Obs) has a published normals product. A grid cell on this stretch of the Sea of Cortez may soften the desert coast’s sharp day-night swing, so real nights may run colder than the lows below.
The month totals 0.53 inches of precipitation, spread over 1.4 days that record at least 0.10 inch. No day in an average February reaches an inch. That makes it the wettest of the three months in our comparison at 0.53 inches, and still a month where you keep one indoor fallback for the day or two that turns gray.
The average high is 68.4°F and the average low 53.8°F, a swing of 14.6 degrees. Pack for both ends of the day: a fleece or light jacket for early mornings and after sunset, short sleeves and sunglasses for the middle, and sunscreen either way.
On February 15 the sun rises at 7:14 a.m. and sets at 6:22 p.m. local time (Hermosillo time zone), for 11 hours 08 minutes of daylight. Dinner plans can wait until after dark, but start a sunset walk on the shore about an hour ahead, because the temperature drops quickly once the light goes.
Can you swim in Puerto Penasco in February? Sea temperature
The Open-Meteo Marine API puts the sea surface off Puerto Penasco at 62.0°F in February, averaged over 2015-2024. That figure is a mean of daily maxima, so it runs a shade warmer than a 24-hour mean would. The water at dawn is likely a little colder than the number suggests.
At 62.0°F you can wade and take a short, bracing dip at Sandy Beach (Playa Mirador) or Cholla Bay, but a long swim is unlikely to appeal. January sits within 0.3 degrees of that at 62.3°F, while March reaches 65.0°F, which is 3.0 degrees warmer.
We found no wind or swell series for February in our sources, so we make no claim about chop or surf. Check a marine forecast on the morning you plan to get in the water.
How busy is Puerto Penasco in February? Crowds and prices
We found no occupancy series and no room-rate data for Puerto Penasco, so we place February in no price tier and rank no month against another. The weather gap between January, February and March is measured and sits in the comparison below. Price and crowd claims would have to come from somewhere else.
We also could not verify a booking lead time for February, so ask each property for its cancellation terms before you pay a deposit. Getting there has changed more than the rooms: Mar de Cortes International Airport went more than five years without scheduled commercial flights, and a new scheduled route resumed service in mid-2026. Most U.S. visitors still arrive by car through the Lukeville-Sonoyta crossing, according to local press (Codigo Rojo Cajeme, Ahora Noticias Penasco).
Sonora’s lodging tax is 3% of revenue under Article 122 of the state’s Ley de Hacienda, in the text published December 26, 2025. We could not verify whether or how that 3% shows up as a line on a guest’s bill, so we quote no total per night.
With the sea at 62.0°F, the upgrade that changes a February stay is a heated pool. Ask before you book whether it is heated, since we could not verify which properties heat theirs.
Things to do in Puerto Penasco in February

February suits anything done on foot and outdoors. A 68.4°F afternoon is comfortable in a light layer, and with 1.4 rain days on average, a beach walk, a long lunch outside or an hour of shell-hunting rarely needs a backup. Water entry stays short and cold.
Two swimming beaches anchor the month: Sandy Beach (Playa Mirador) and Cholla Bay, both on the Sea of Cortez. Sandy Beach is the easier one to build a day around. We did not verify fees, hours or parking at either, so we quote none.
The water barely moves through the winter: 62.3°F in January and 62.0°F in February. The air is what changes, with the average high climbing 3.9 degrees by March. February’s shoreline is therefore a jacket-then-sleeves experience, colder at the edges of the day than at midday.
We could not verify which beach areas are free in February, and we found no February event dates, so we name none. Ask your hotel or a local vendor before you plan around a schedule.
Puerto Penasco itinerary for February
Day one: be on Sandy Beach (Playa Mirador) at the 7:14 a.m. sunrise, jacket on, because lows average 53.8°F. Walk the shore while the light is low, then eat breakfast in town and wade in around midday when highs reach 68.4°F. Spend the afternoon outside, and be back at the water about an hour before the 6:22 p.m. sunset.
Day two: take the morning at Cholla Bay, with the same layers and the same rule about the sunset. If the day turns gray, an event that happens on only 1.4 days in an average February, swap it with a slower day of a long indoor lunch and save the beach for the next one. Leave enough daylight (11 hours 08 minutes) for any drive home.
Puerto Penasco in February vs January and March
| Puerto Penasco | January | February | March |
|---|---|---|---|
| Average high | 67.2°F | 68.4°F | 72.3°F |
| Average low | 51.9°F | 53.8°F | 57.8°F |
| Precipitation | 0.36 inches | 0.53 inches | 0.34 inches |
| Days with 0.10 inch or more | 1.1 | 1.4 | 1.0 |
| Sea surface (Open-Meteo Marine API, 2015-2024) | 62.3°F | 62.0°F | 65.0°F |
Air figures for all three months are ERA5 normals for 1991-2020 over the same grid cell. Highs climb from 67.2°F to 68.4°F to 72.3°F, and lows from 51.9°F to 53.8°F to 57.8°F. February is the wettest of the three at 0.53 inches and the coolest for the sea at 62.0°F.
Waiting four weeks for March buys 3.9 degrees on the average high, 4.0 degrees on the low and 3.0 degrees on the sea, along with 0.19 inches less rain. Going four weeks earlier costs 1.2 degrees on highs and 1.9 degrees on lows for about the same sea. What either shift does to room rates we cannot say, because we found no rate data.
Is February a good time to visit Puerto Penasco?
Yes, for anyone whose plan is walking the shore, sitting outside and getting mild, mostly dry days in a jacket-and-sunglasses climate. No, for anyone counting on long swims, and no for anyone who reads the Level 3 Sonora advisory and decides the trip is not for them.
If a swim matters, aim for March, with its 65.0°F sea, 72.3°F highs and 1.0 rain day. Other months are laid out in our month-by-month planner. Other places to go are in our destinations index.
February pairs 68.4°F afternoons with 11 hours 08 minutes of daylight and 1.4 rain days, which is enough light and dry ground for two full days on the shore.
The last word
Go in February for the walks and the low sun, and keep March for the swim. Either way you are at the edge of the Alto Golfo de California y Delta del Rio Colorado Biosphere Reserve, decreed a federal protected area on June 10, 1993, and the refuge of the vaquita marina and the totoaba. Leave the shells and the tide line as you found them.
