Best Time
Having a great climate, Chula Vista can be visited all year round. However, from December to March, it can rain, and it can get a bit cold at night. In May and June, there may be morning mists. In summer, but especially in September and October, there can be very hot days, when the wind blows from the desert.
The best time to go to the beach is from July to October, when the sea is less cold.
