Los Angeles has the driest big-city climate in the country, a Mediterranean pattern that gives you long warm summers, mild winters, and a brief winter wet season. The famous marine layer rolls in most mornings between May and September, burning off by lunch. Rain is rare — most years see fewer than 40 days with measurable precipitation, with almost all of it falling between November and March. Inland valleys run dramatically hotter than the coast, and the fall Santa Ana winds can spike fire risk and push downtown temperatures well past 100°F.
