Annual Humidity Patterns

Sintra, Portugal experiences a Mediterranean climate, characterized by warm, dry summers and mild, wet winters. Humidity levels vary throughout the year, with summer typically being the driest season and winter the most humid. In the summer months (June-August), average humidity hovers around 60-70%, providing a comfortable and breathable atmosphere. However, in winter (December-February), humidity rises significantly, reaching average levels of 80-85%. This increase in humidity is primarily due to the influx of moisture-laden air from the Atlantic Ocean, which brings frequent rainfall and cloud cover.

Seasonal Variations

The humidity in Sintra also varies considerably on a daily basis, particularly during the summer months. In the early morning hours, humidity levels tend to be highest, often reaching near saturation. As the day progresses and the sun gains strength, humidity levels gradually decrease, reaching their lowest point in the afternoon. This diurnal pattern is driven by the evaporation of water droplets from the ground and vegetation, which increases humidity in the morning and reduces it as the day goes on. During winter, humidity levels tend to be more consistent throughout the day, as the constant influx of moisture from the ocean minimizes the effects of evaporation.
