Traveller notes on La Paz, Baja California in September
Notes from nearby Los Cabos (145 km away)
La Paz, Baja California doesn't have its own notes for September yet — these are about Los Cabos, close enough to share the season.
Cabo-forum threads on September weather are direct that it's the least favorable month by the numbers - hurricane season proper, hot and humid with the year's heaviest rainfall, and the standing advice is to check the tropical storm outlook before booking flights. That said, regulars are equally direct that most Septembers pass without a direct hit, delivering brief, heavy downpours that clear fast and leave the desert visibly greener along with some spectacular sunsets rather than a washed-out trip. A practical side effect: several restaurants close for part of the month since it's their slowest stretch, worth checking ahead. Prices and crowds both drop accordingly, the trade-off for the weather risk. The record: 32.3C days feeling like a sticky 39C, 26.6C nights, 120mm across 10.8 days, a 30.2C sea, 79 percent humidity and 10.7 hours of sun - the heaviest rain month on Cabo's whole calendar, exactly matching the hurricane-season framing.
Other months in La Paz, Baja California
Forum posters describe August as La Paz's warmest, most humid month, with daytime temperatures commonly cited in the high 90sF and posters noting rain, while possible, actually falls infrequently despite August sitting within the broader May-October hurricane season. Posters describe the mid-August-through-mid-October stretch specifically as when humidity and the chance of a tropical storm both climb, making it something of a gamble rather than a guaranteed washout. Posters do flag a genuine upside: August is a notably quiet, uncrowded time to visit compared to the winter high season. Posters generally rate August as hot and humid with real but modest storm risk for La Paz, appealing mainly to travelers prioritizing low crowds over ideal comfort.
Forum posters call February the coolest month of the year here - comfortable enough to sit on the beach at midday, but the water itself (around 60F) is too cold for most people to enjoy swimming without a wetsuit. The upside: it overlaps with prime whale season nearby (roughly a 3-hour trip), plus Carnaval festivities in town. Regulars say the standard February routine is beach lounging and walking in the sun rather than water time - the pool may be comfortable by midday, but the open water stays a cold-water activity this time of year.
