Best time to visit Porto Alegre

April is the best month in Porto Alegre, scoring 78 out of 100, with January the weakest at 60. The 18-point spread means timing is worth planning around without being decisive. The good window runs March to December — 10 months within ten points of the best.

February is the warmest month at 29.8 °C and July the coolest at 18.8 °C — a 11 °C spread across the year. Around 51 days a year top 30 °C, concentrated in February and the months either side.

Rain is spread evenly through the year — between 11 and 15 wet days in every month — so there is no dry season to aim for and no wet one to dodge. Whatever you plan, the odds of rain are much the same.

The sea is comfortable for swimming in January, February, March, April and December — 25.3 °C at its warmest against 16.5 °C at its coldest. The water peaks a month or two after the air does, so the best swimming falls later in the year than the best weather. Daylight runs from 10.2 hours in winter to 14.1 in summer, enough to notice on a sightseeing itinerary.

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