Los Angeles enjoys a Mediterranean climate with mild, wet winters and hot, dry summers that stretch on longer than most residents care to admit.
Rain is largely confined to November through March, meaning you'll need a light jacket for those months but can otherwise leave waterproofs at home for half the year.
Temperatures range from the low 60s°F in winter to the mid-80s°F in summer, though inland valleys routinely hit triple digits while coastal areas stay stubbornly cooler.
The famous marine layer brings morning fog and dampness to coastal neighborhoods, burning off by afternoon and creating a persistent need for layering.
The city's microclimates mean carrying a light layer in your car year-round is the most LA thing you can do besides complaining about traffic.
