Climate chart - Tijuana
The climate of Tijuana is arid sub-tropical, with very mild, relatively rainy winters and warm, sunny summers. The climate resembles that of Los Angeles, although it is even more arid.
The city is located in northwestern Mexico, near the Pacific coast, where a cold current flows. Across the border with the United States is San Diego.
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).
In summer, the neighborhoods closest to the sea are cooler, while the temperature increases as you move further away from the coast. In August, the maximum temperature is 25 °C (77 °F) on the coast, 27 °C (81 °F) at Tijuana airport, and 31 °C (88 °F) in Maclovio Rojas, 30 km (18 mi) away from the coast.
All year round, but especially from April to November, with a maximum in autumn, the temperature can increase a lot when the Santa Ana blows, the wind from the deserts of the interior. In September 2010 the temperature reached 41 °C (106 °F).
Occasionally, from June to October, but with a higher probability in September, the city may be affected by the remnants of a hurricane from the Pacific to the west of Mexico. Typically, the main effects are heavy rainfall or scattered thunderstorms.
