California Weather Radar by City

Los Angeles

Los Angeles radar covers the Southland, where Pacific storms bring most of the year's rain in winter. Watch it for atmospheric river events, when a narrow band of tropical moisture can drop very heavy rain on the coastal mountains and valleys.

San Diego

San Diego radar covers the southernmost California coast, tracking Pacific storms as they arrive and the rain bands that follow. San Diego's radar is also the last California view of storms moving in from the Pacific before they head inland.

How to Use This California Radar Hub

Start with the statewide radar loop above for the big picture, then open a city radar below for street-level detail. The live warnings feed shows current National Weather Service alerts for California, so you can see at a glance whether any part of the state is under a warning right now.

For a wider view, the regional radar page covers neighboring states and the same storm systems from a different angle. During hurricane season, coastal city radars are the ones to watch first; during severe weather season, inland city radars show storms as they develop.

Frequently Asked Questions: California Weather Radar

Where can I see live California weather radar?
This page shows a live California Doppler radar loop at the top, with current National Weather Service warnings for California below it. For street-level detail, open a city radar for Los Angeles or San Diego from the links below.
What is an atmospheric river?
An atmospheric river is a narrow band of concentrated moisture in the atmosphere that flows from the Pacific toward the West Coast. When it makes landfall, it can bring days of heavy rain, flooding, and mountain snow to California, which is why atmospheric river storms are tracked closely on this radar.
When does California get most of its rain?
Most of California's rain falls in winter, when Pacific storm systems move onshore. Summers are usually dry, especially in the south, so winter radar activity is the best time to follow California storms on this page.
Why does the radar sometimes show rain offshore that never reaches land?
Pacific storms often weaken or shift direction before landfall, and coastal mountains can squeeze out moisture before it reaches inland valleys. The statewide loop helps you see whether a band of rain is holding together, breaking apart, or stalling offshore.
