Sometimes, there may also be cold periods brought by air masses from Eastern Europe, though the effects are not very evident.

Summer, from June to August, is hot and sunny, with rare thunderstorms. During the day, the sea breeze makes the heat more bearable, but nights are muggy.
There may be some particularly hot periods, usually of short duration. On the hottest days of the year, the temperature typically reaches 36/37 °C (97/99 °F). The heat record is 40.5 °C (105 °F) and was recorded in July 2009.

Best Time

The best time for a beach holiday on the coast near Castellón de la Plana (for example in Benicàssim) is the summer, from June to August. The water temperature is comfortable enough from July to September; however, in September, which is still a good month (especially in the first half), the first Atlantic depressions begin to affect this area. May and June are sunny months, but the sea is still a bit cool, especially in May, when it is actually a bit cold.
Although good weather is not always guaranteed, spring and autumn are ideal for visiting the city, since it can be very hot in summer.
