Best time to visit San Francisco: weather, crowds and events by month

San Francisco sits on the Pacific coast of Nayarit, so it follows the same rhythm as the rest of Mexico's Pacific shore: a dry, comfortable winter and a hot, wet summer. The dry season runs roughly November to April, with sunny days, low humidity and cool nights. The wet season runs May to October, with heavy afternoon showers, high humidity and hurricane risk that peaks in September.

The trade-off is simple. Dry-season weeks give you reliable beach weather but the highest room rates and the fullest buses around Semana Santa and Christmas. Wet-season weeks are cheaper and quieter, but you plan around rain and keep an eye on storm forecasts. If you want the best odds of a dry, easy trip, aim for late November to March, avoiding the Easter and Christmas peaks.

In the dry season (November–April) expect warm, sunny days and noticeably cooler evenings. This is the stretch for beach days, boat trips and outdoor meals without watching the sky. Bring a light layer for the evening; coastal nights in December and January can feel cool after a hot day.

In the wet season (May–October) the heat and humidity climb and rain usually arrives in the afternoon or evening, often hard and short. Mornings are frequently clear, which is why many travellers still get a full beach morning before the weather turns. September is the month to treat with most caution: it is the wettest and carries the highest hurricane risk on Mexico's Pacific coast.

The two peaks to plan around are Semana Santa (Easter week, March or April) and the Christmas–New Year period. Both are Mexico's biggest travel weeks, when domestic visitors fill beaches, buses and hotels, and rates rise. Book accommodation and any long-distance transport well ahead for those dates.

Outside those peaks, the dry season is busy but manageable, and the wet season is the cheapest and quietest stretch. If you are flexible, June to October — avoiding holiday weekends — gives the lowest room rates and the emptiest beaches, at the cost of planning around rain.

Mexican public holidays move the domestic travel market more than anything else. Semana Santa is the single biggest week of the year for beach travel, and Christmas–New Year is close behind. Long weekends around Constitution Day (first Monday of February) and Benito Juárez Day (third Monday of March) also fill short-haul routes.

Independence Day (15–16 September) brings parties nationwide, and Día de Muertos (1–2 November) is a major travel period elsewhere in Mexico — Oaxaca and Pátzcuaro in particular — which can affect transport connections. Carnival (February or March) is big in Veracruz and Mazatlán rather than here, but it still adds demand on some routes.

There is no reliable published price list for this stretch of coast, so treat the figures below as 2026 estimates for planning rather than quotes. The pattern is consistent: dry-season and holiday weeks cost the most, wet-season weeks the least, and the gap between them is often large enough to change where you stay.

Transport is the other variable. San Francisco is in Nayarit, reached by road from Tepic or Puerto Vallarta; check transfer times and fares locally before you commit to a route.

Book the two peak weeks first and build the rest of the trip around them. If your dates are flexible, shift a week either side of Semana Santa or Christmas and you will usually find better rates and quieter beaches.

In the wet season, plan outdoor activity for the morning and keep the afternoon loose. Carry a light rain layer rather than an umbrella, and check storm forecasts if you are travelling along the coast in September or early October. For connectivity on the road, an eSIM set up before you fly avoids hunting for a local SIM on arrival.
