Traveller notes on Puerto Escondido in September
Other months in Puerto Escondido
Regulars are specific real rain essentially tapers off starting this month, November through March or April widely regarded as the best window here, a trip genuinely unlikely to see a drop of rain during this stretch. Our row backs that hot, genuinely dry read, 30.4C reading as a scorching 36C, over 23.2C nights feeling 27C, with rain light at 25.7mm across 6.6 days and humidity at 84 percent. Regulars are consistent the whole September-through-January run reads as close to perfect weather-wise, daytime temperatures commonly cited in the low-to-mid 80s Fahrenheit throughout. The sea sits at a bath-warm 29.9C. The record: 10.4 hours of sun, a 10.6 kph wind and AQI 31.
Regulars name the winter-into-spring stretch, running roughly November through this month, as the reliably dry window here, with a drop of rain highly unlikely on any given day before the pattern changes moving into May and June. Our row backs the dry read directly, just 4.9mm of rain across 1.6 days, alongside real heat, 30.6C reading as 35C at 74.4 percent humidity, over 24.4C nights. Surf is called out as a specific draw of this transitional month, with conditions still lively before the wetter, muggier stretch that regulars say builds from June through October. The sea sits at a warm 27.9C. The record: 11.4 hours of sun, a 15.2 kph wind and AQI 42.
March closes the busy season here, which regulars date December to March, and the swell is a little further along than January's. Their practical division is by beach rather than by month: Carrizalillo is the calm cove, quite flat with small waves in early March and swimmable through the whole winter, while the surf beaches carry enough size by February and March to make swimming there hazardous even when the waves are not huge. The roughest water of the year comes with the summer rains, and the surf competition is held in late November. Our row is the dry, hot version of Mexico's Pacific: 30C reading as 34C, 4.4mm across 0.8 precipitation days, and a 27.3C sea. The record: 23.4C nights, humidity 75 percent, 11 hours of sun and AQI 34.
January is the dry, hot heart of the Puerto Escondido season - our row gives 29.7C reading as 33C with 5.3mm of rain across 1.4 days and a 27.4C sea - and it is also, regulars report, when the famous surf is at its smallest. Visitors in January describe waves that were simply not that big, with one reporting no high surf at all across a whole stay. That is a plus or a minus depending why you came. What does not change is the danger: Zicatela and La Punta are too much for beginners in any month, lifeguards move people out of the water at Zicatela without a board, and the world competitions are held here for a reason. High season also means far more traffic in town. The record: 22.3C nights, humidity 77 percent, 10.4 hours of sun and AQI 32.

South swell season
15 Apr – 15 Oct · usuallySurf seasonRiskThe southern-hemisphere swells arrive from April and Zicatela turns into the heavy beachbreak it is known for, which is not a beginner's wave in those months. Carrizalillo and La Punta stay manageable.

Pacific hurricane season
15 May – 30 NovThe eastern Pacific season opens in mid-May and runs to the end of November. Storms here tend to graze the coast rather than land on it, but the town has taken direct hits in September and October. Source ↗
