Best time to visit Puntarenas

December is the best month in Puntarenas, scoring 70 out of 100, with May the weakest at 40. The 30-point spread means timing is worth planning around without being decisive. Only 3 months come close to the top, which makes the timing narrow.

March is the warmest month at 35.4 °C and October the coolest at 29.3 °C — a 6.1 °C spread across the year. 272 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season.

There is a real wet season here. May to October carry the rain — up to 26 wet days in a month — while January, February, March and December drop as low as 2. That 24-day gap is the biggest single difference between a good month and a bad one in Puntarenas, and it moves further than the temperature does.

The sea never drops below 27.7 °C, so swimming is on the table year round. Daylight barely moves: about 12.7 hours whatever the month, which removes one variable from the decision entirely.

The three strongest months are December, January, February. The one to think twice about is May. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
