Climate Chart of Guimarães, Portugal

Climate overview

Temperature

The monthly mean temperature is lowest at 8.3 °C in January, giving visitors who prioritise cooler monthly averages a clear point of reference. The highest monthly mean is 22.0 °C, shared by July / August. These are averages for whole months, not daytime maximum temperatures, and they do not describe the full range of conditions a visitor might encounter within a day. Across the calendar-month means, the unweighted mean is 14.8 °C. It is a broad summary rather than a day-weighted annual average, and it should not be read as a temperature expected throughout the year.

Rain

Mean daily rainfall reaches its highest monthly level at 7.36 mm/day in October. Visitors planning outdoor activities around that period may wish to prepare for rain, while remembering that this daily average does not indicate how often rain falls or guarantee the conditions on a particular day. The lowest monthly mean daily rainfall is 0.62 mm/day in August, which can be a conditional option for travellers prioritising lower average rainfall. The unweighted mean across the monthly daily averages is 4.53 mm/day; neither figure is a monthly total or a promise of dry weather.

Sunshine

Mean daily sunshine duration is highest at 12.68 hours/day in July, a useful reference for visitors planning around average sunshine for outdoor sightseeing. Its lowest monthly mean is 5.56 hours/day in December. These figures describe average sunshine duration, not day length or guaranteed clear skies. The unweighted mean of the monthly sunshine averages is 9.02 hours/day per day. It offers an overview across the calendar months, but does not predict the sunshine available on any specific travel date.

Snow

The highest monthly mean daily snowfall is 0.02 mm/day, shared by January / March. This small recorded average does not establish how many days have snowfall, whether snow accumulates or remains on the ground, or whether conditions suit skiing.
