Temperature
The warmest monthly mean temperature is 23.2 °C in January, while the coolest is 11.1 °C in July. These are monthly averages rather than daytime highs, so individual days may feel warmer or cooler.

Rain
Mean daily rainfall is highest at 3.58 mm/day in February and lowest at 2.09 mm/day in June. The figures are daily means, not monthly rainfall totals, and they do not show how often rain falls or guarantee conditions on a particular day.

Sunshine
Mean daily sunshine reaches its highest level at 11.78 hours/day in December and its lowest at 6.54 hours/day in July. This can help with planning daylight outdoor activities, although sunshine duration is not the same as day length and does not promise clear skies on a given day.

Best Travel Time Guide for Montevideo, Uruguay: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly averages, July is the relevant option, with a mean temperature of 11.1 °C; this is not a prediction of daytime highs or the weather on individual dates. Those prioritising lower average daily rainfall could consider June, when the mean is 2.09 mm/day, while packing rain protection is sensible for travel in February, the month with the highest mean daily rainfall at 3.58 mm/day. Neither average tells you how frequently rain occurs or guarantees a dry or wet day.
For planning around mean daily sunshine, December has the highest figure at 11.78 hours/day, while July has the lowest at 6.54 hours/day. These comparisons may help when daylight outdoor sightseeing is a priority, but sunshine duration is not day length and cannot ensure bright conditions during a visit.
