MEXICO · ENSENADA · SEPTEMBER
September in Ensenada is dry, mild and a little cool at the edges. Afternoons reach about 74.3°F, mornings start near 58.3°F, and the whole month’s rain adds up to 0.10 inches. The Pacific sits at 67.0°F and the daylight lasts just over twelve hours.
Ensenada is the base for three very different outings: La Bufadora, a marine geyser on the Punta Banda peninsula, Valle de Guadalupe, the wine valley inland, and the road toward the Sierra San Pedro Mártir range. September’s dry afternoons suit all three, and the neighboring months are close enough in the numbers that your choice comes down to nights and swimming.
THE MONTH AT A GLANCE · ENSENADA · SEPTEMBER
September gives Ensenada dry days near 74°F and cool nights near 58°F, with a 67.0°F sea that suits a wade more than a long swim.
DRY · HIGH 74.3°F · LOW 58.3°F · SEA 67.0°F
Go for: dry afternoons in the mid-70s °F, plus La Bufadora and Valle de Guadalupe on the same trip.
Think twice before: planning long swims. The sea is 67.0°F, and 58.3°F mornings call for a jacket.

Ensenada has no commercial airport of its own. The nearest international one is Tijuana (TIJ), so that is where the flight search points. The U.S. State Department’s Mexico advisory, reissued May 29, 2026, lists Baja California at Level 3 (reconsider travel) for terrorism, crime and kidnapping, and places the high homicide numbers in non-tourist areas of Tijuana. Its only travel restrictions in the state cover Mexicali Valley, and it lists none for the rest of Baja California.
Ensenada weather in September

| Average low | 58.3°F |

Every air figure here comes from Mexico’s official 1991-2020 normals, published by the national weather service (Servicio Meteorológico Nacional, part of CONAGUA) for station 02108 at Punta Banda. That thermometer sits about 11 miles south of downtown on the same bay and is the nearest official one, since Ensenada’s own town-center station has no published normals. Treat the numbers as the bay’s climate rather than a reading taken at your hotel door. September averages a high of 74.3°F, a low of 58.3°F and 0.10 inches of precipitation.
Measurable rain falls on 0.3 days in an average September, which works out to about one wet day every three Septembers. The service does not publish its threshold for a rain day on the station sheet, so “measurable” has no exact cutoff we can quote. A tenth of an inch for the whole month means an umbrella can stay home and the outdoor days need no rain plan.
Afternoons top out at 74.3°F and mornings bottom out at 58.3°F, a 16.0°F swing. Short sleeves suit the afternoon, and early starts and evenings want a light layer. A heavy coat stays home.
On September 15 the day runs 12 hours 23 minutes, with sunrise at about 6:29 a.m. and sunset at about 6:52 p.m. We converted sunrise-sunset.org’s UTC times to America/Tijuana time. After sunset, dress for the 58.3°F low.
Can you swim in Ensenada in September?
Yes, at 67.0°F. That is the September sea-surface average off Ensenada from the Open-Meteo Marine API, taken over 2015-2024 as a mean of daily maxima. It runs a shade warmer than a full 24-hour average would, because it leaves out the cooler night and dawn readings.
At 67.0°F the Pacific is cool water: comfortable for wading and a short dip, and the range where many people reach for a wetsuit before laps or a long paddle. The same data gives 67.5°F for August and 65.3°F for October, so waiting a month gains half a degree and moving on costs 1.7°F.
Our sources carried no wind or swell figures for September, so we say nothing about surf or chop. Check a marine forecast for the day if you plan to paddle or take a boat out.
How busy is Ensenada in September?
We found no occupancy series and no monthly room-rate table for Ensenada, so we crown no month expensive or cheap. The one crowd figure we can source is annual: the port received 360 cruise ship calls in 2025, 24% more than in 2024, bringing more than 1.3 million cruise passengers to the municipality (city government release, April 4, 2026). Spread evenly, that is close to one ship a day, but the release gives no month-by-month split, so September’s share stays unknown.
We also found no data on how many weeks ahead Ensenada rooms fill in September, so no lead time goes here. The booking with no local substitute is the flight to Tijuana (TIJ), because Ensenada has no commercial airport of its own. Fix that first, then the room.
Baja California charges a lodging tax, the Impuesto sobre Servicios de Hospedaje, at 5% for hotels and 7% for motels in 2026, with a 5% rate applying to bookings made on digital platforms. We could not verify whether a quoted room rate already includes it, so compare totals at checkout.
The one premium September does not need is a flexible rate bought against rain. With 0.3 rain days and 0.10 inches for the month, weather is a poor reason to pay more. If you pay extra for flexibility, do it for the flight or for a change in the State Department advisory.
Things to do in Ensenada in September
With 0.10 inches of rain and 0.3 wet days, September is a month for fixing outdoor days in advance and keeping them. Afternoon highs of 74.3°F suit a day on the coast, and the light holds until about 6:52 p.m.
La Bufadora is a marine geyser on the Punta Banda peninsula, about 20 miles southwest of Ensenada, that shoots a plume of seawater through a coastal blowhole, reaching as high as 30 meters (about 100 feet). Valle de Guadalupe, the wine valley inland from Ensenada, is promoted by the state as the Ruta del Vino.
How tall the plume runs in September depends on the swell, which our sources do not cover. The 30 meters is a ceiling, and we have no September height. What the month does change is the air around it: a 74.3°F coastal afternoon suits standing at the blowhole in a T-shirt, while a 58.3°F morning wants a layer. The valley sits inland and we hold no inland normals, so do not read the coastal figures onto the vines.
We verified no admission fees, parking charges or free days for La Bufadora or any Ruta del Vino stop, so we quote none and list nothing as free. Ask at each place before you count on it.
Ensenada itinerary for September
Day one, the coast. Sunrise comes at about 6:29 a.m. and mornings sit near 58.3°F, so leave after breakfast with a layer and drive the roughly 20 miles southwest to La Bufadora on the Punta Banda peninsula. Give the plume the middle of the day, as the air climbs toward its 74.3°F high, and be off the peninsula road before the 6:52 p.m. sunset.
Day two, the valley. Head inland to Valle de Guadalupe and the Ruta del Vino, and line up a driver or a designated driver before the first tasting. The coastal normals do not describe the valley, so carry the layer anyway. If a wet day does turn up (about one every three Septembers on average), swap the two days so the coast gets the clearer one.
Ensenada in September vs August and October
| Measure | August | September | October |
|---|---|---|---|
| Average high | 75.0°F | 74.3°F | 72.7°F |
| Average low | 60.1°F | 58.3°F | 53.6°F |
| Day-night gap | 14.9°F | 16.0°F | 19.1°F |
| Precipitation | 0.04 in | 0.10 in | 0.41 in |
| Days with measurable rain | 0.2 | 0.3 | 0.7 |
| Sea surface (mean of daily maxima, Marine API) | 67.5°F | 67.0°F | 65.3°F |
All three months’ air figures come from the same Punta Banda station and the same 1991-2020 normals, while the sea temperatures come from the Open-Meteo Marine API for 2015-2024. From August to October the average high slides from 75.0°F to 72.7°F, the low falls from 60.1°F to 53.6°F, and rain grows from 0.04 to 0.41 inches, about four times September’s 0.10. The cooling concentrates at night: 1.8°F into September, then 4.7°F into October.
Shifting to August buys 0.7°F by day, 1.8°F by night and 0.5°F in the sea, with slightly less rain (0.04 inches against 0.10). Moving to October costs 1.6°F by day, 4.7°F by night and 1.7°F of sea warmth, and rain days more than double to 0.7. We found no room-rate or occupancy data for any of the three months, so we cannot say which is cheaper.
Is September a good time to visit Ensenada?
Yes, if you want dry days in the mid-70s, cool nights and a coast you can plan around: 0.3 rain days, a 74.3°F high and 12 hours 23 minutes of daylight on the 15th. It suits a trip built on La Bufadora and the Ruta del Vino. It suits swimmers less, since the sea is 67.0°F and a long swim will feel cold.
If cold water or chilly nights are what bother you, August is the month to prefer, though it moves little: 60.1°F nights and a 67.5°F sea against September’s 58.3°F and 67.0°F. If you like cooler air and a bigger day-night swing, October has them, at 53.6°F nights and 0.41 inches of rain. Nothing fits? Our guide to when to travel, month by month covers the rest of the year.
September pairs 58.3°F nights, still 4.7°F milder than October’s, with rain that barely registers at 0.10 inches.
The last word
Book September for dry days and jacket-weight mornings, and keep the swim short. If the clear sky tempts you toward the mountains, Ensenada is the usual overland gateway to Sierra San Pedro Mártir National Park, a CONANP-protected range that hosts Mexico’s National Astronomical Observatory. We hold no mountain weather figures, so check the park’s conditions before you drive up.
