Weather in San José in November

Costa Rica · 20-year averages, November

A good month. November is a solid month to be in San José. You should expect rain on 22 days of the month, which is more days wet than dry.

November ranks 12 of 12 — near the bottom of San José's year. February is the month that works, and the swing between the two is 24 points, which is a different holiday rather than a slightly better one. Worth keeping in perspective: November is the weakest month of San José's year and it is still a perfectly good one. The downside here is small.

Rain on 22 of the month's 30 days, 4 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average November reaches 30 °C. Across the twenty years measured, the hottest November day reached 26.5 °C and the coldest night fell to 13.1 °C, and the wettest single day dropped 259 mm — roughly 139% of the month's rain in one day.

November is moderately variable: 94 mm in the driest year against 767 mm in the wettest, around an average of 187 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind is light at 1.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 90%, high enough to notice on the warm days without dominating them.

How November sits in the year

Temperatures hold steady either side: 22.6 °C in October, 23 here, 23.7 in December. Nothing about the timing within the month matters much. Rain is the thing that moves: December brings 8 days less of it, so pushing the dates later buys drier weather.

Daylight in November

San José sits close enough to the equator that daylight barely moves all year — 11.7 hours in November, against a range of just 1.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 12 °C between the year's warmest afternoons and coldest nights. At 1133 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

November in San José versus nearby

If San José is one option among several, the nearby comparison is worth making. San Isidro is close enough to be a coin toss — 2.7 °C warmer, 3 days more rain. Puntarenas is the weaker option in November — 6.8 °C warmer, 4 days less rain.

So: November is a compromise. February is 24 points better and is what San José is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
