Summers are long and warm, with daytime temperatures in the 80s and 90s and nights in the 70s. Coastal breezes, however, normally preclude extreme heat. Winters are short and mild, generally from early December through early February with daytime highs in the 50s.
Snow is extremely rare.
The moderate year-round climate allows for very few hot or extremely cold days. Even in summer, most women wear a shawl or light sweater for cool evenings and air conditioned restaurants. Some dining establishments require jackets for the men. A raincoat can come in handy during any season.
