The climate of Playas de Rosarito is
arid sub-tropical, with very mild, relatively rainy winters and warm, sunny summers.
The city is located on the Pacific coast, south of Tijuana. Here, as in southern California and Baja California, a cold sea current makes the climate particularly mild and arid.
The
winter is very mild, with many sunny days, although there may be some rainy days. At night, the temperature can sometimes drop to 1/2 °C (34/36 °F).
Occasionally, from June to October, but with a higher probability in September, the city may be affected by the remnants of a
hurricane coming from the Pacific to the west of Mexico. Typically, the main effects are heavy rainfall or scattered thunderstorms.
The
average temperature of the coldest months (January, February, March) is of 14.5 °C (58.1 °F), that of the warmest month (August) is of 21 °C (69.8 °F). Here are the average temperatures.

Best Time
Having a great climate, Rosarito can be visited all year round. However, from December to March, it can rain, and it can get a bit cold at night, especially in inland areas. 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.
