Wednesday afternoon high temperatures will be above seasonal average.

  • Coastal highs 79°-90°, normal around 72°.
  • Inland highs 88°-95°, normal around 80°.
  • Mountain highs 78°-87°, normal around 67°.

At the beach, the rip current risk is low with water temperature 62°-67°. Waves are 2'-3' with swells from the south-southwest and northwest.

Clear skies remain over the County thanks to a lack of marine layer. Dry air lingers over the area but coastal temperatures will be 5-10 degrees cooler thanks to the return of some onshore flow. Inland areas will benefit little from the cooling. Offshore flow will strengthen again later Wednesday night.

The UV index will peak at 5 Wednesday, which is considered Moderate. Sun protection is recommended, UV radiation from the sun will cause skin damage. The time between 10 AM and 4 PM is when UV radiation from the sun is at its maximum.

RED FLAG WARNING:

Red Flag Warning
KFMB Weather

A Red Flag Warning has been issued for the inland and mountain areas from 5 AM Thursday until 5 PM Friday. Offshore winds return Wednesday night, ushering in dry desert air. Sustained winds 25-35 mph can gust up to 60 mph on Thursday. Relative humidity values drop to 5-10%, with poor recovery overnight. 

THE WEEK AHEAD:

Surface level high pressure will build over the Great Basin as the Pacific high off the West Coast nudges northeast. Offshore winds will begin to flow Wednesday night and will be strongest Thursday morning. Santa Ana conditions will bring critical fire concerns through the rest of the week.

A trough of low pressure will bring an end to warm and dry air for the coming weekend. Offshore winds will die down Friday afternoon as the trough approaches.

Temperatures will drop nearly 10 degrees between Saturday and Sunday for most of the County. Cooler temperatures will continue through Monday.

High pressure over the Eastern Pacific is forecast to nudge towards the West Coast midweek next week. This may result in another Santa Ana wind event Tuesday thru Thursday.
