Laguna Beach weather

Laguna Beach weather by month

These are NOAA’s 1991 to 2020 U.S. Climate Normals for the Laguna Beach station. A normal is a 30-year average, so any single day can run warmer, cooler or wetter. Ocean temperatures come from a buoy whose readings NOAA publishes, covered below the table.

Month	Avg high	Avg low	Rain	Days with 0.10 in or more	Ocean (typical)
January	68°F	44°F	2.78 in	4.9	60°F
February	68°F	45°F	3.39 in	5.3	59°F
March	69°F	48°F	1.62 in	3.2	59°F
April	73°F	50°F	0.80 in	2.0	60°F
May	75°F	55°F	0.20 in	0.7	62°F
June	76°F	58°F	0.11 in	0.5	66°F
July	80°F	60°F	0.11 in	0.1	68°F
August	81°F	61°F	0.02 in	0.0	70°F
September	81°F	59°F	0.16 in	0.4	70°F
October	77°F	55°F	0.49 in	0.9	68°F
November	72°F	49°F	1.13 in	1.4	64°F
December	67°F	44°F	1.87 in	3.2	62°F

Warm and dry from May to October

Average highs climb from 75°F in May to 81°F in August and September, and they ease to 77°F in October. Average lows run from 55°F in May to 61°F in August. Rain is rare in these months. No month from May through October averages more than half an inch, and August averages 0.02 inches. The count of days with 0.10 inch or more is under one for each of those six months.

Rain falls from November to April

Of the 12.68 inches the normals add up to in a year, 11.59 inches arrive from November through April. February is the wettest month at 3.39 inches, followed by January at 2.78 inches. Counting days with 0.10 inch or more, February averages 5.3 and January 4.9.

Winter days stay mild by the numbers. Average highs sit between 67°F and 68°F from December through February, and December is the coolest month. Nights run about 23 to 24 degrees cooler than the days in those months: average lows are 44°F in December and January and 45°F in February.

Marine layer, May Gray and June Gloom

NOAA explains that cold ocean water cools the air above it, and that this cooled air, trapped under a temperature inversion, is the marine layer. The layer can cool until clouds or fog form low to the surface, and on the West Coast it can persist for days or weeks, particularly along the coasts of Central and Southern California. Because it persists in early summer, NOAA says, people in Southern California often call it May Gray or June Gloom. Laguna Beach is on that coast, so plan for cloud on some May and June mornings, and check the day’s forecast before you go.

Ocean temperature

The ocean figures come from station 46253, San Pedro South, a Scripps Institution of Oceanography buoy whose readings NOAA’s National Data Buoy Center publishes. It sits about 23 miles west of Laguna Beach. The figures below average its readings from 2015 through 2025 by calendar month.

• Coldest: about 59°F in February and March.
• Warmest: about 70°F in August and September.
• Fall: 68°F in October and 64°F in November.

The buoy sits offshore in 66 meters of water, so use its numbers as a guide to the season, not as a reading at the shoreline. For wind, waves and rip currents on the day you visit, see ocean safety. Whale season and the other seasonal draws are on the whale watching and events pages.
