Winter, from December to February, is mild, but also quite rainy. Very cold days are rare, although sometimes at night the temperature can drop to freezing (0 °C or 32 °F) or a little below.

Spring, from March to May, is mild; it's initially unstable and rainy in March, and gradually becomes more stable and sunny.

Summer, from June to August or mid-September, is hot and sunny; given the proximity to the ocean, here summer is not as hot as in the cities that are located in the interior, near the border with Spain. Sometimes, however, it can be very hot, with highs about 35 °C (95 °F).

Autumn, from mid-September to November, is initially warm and sunny, but over the weeks it gradually becomes milder and wetter.


The amount of sunshine in Fátima is great in summer, when blue skies prevail, it's good in spring, while it's only decent in autumn and winter, when cloud systems due to disturbances from the Atlantic Ocean pass quite frequently.
