Temps cooler before a big warmup this week

Weather Update: Saturday, June 23, 2018 (12:30 p.m.)

Cooler weekend for the County due to a low pressure trough moving through the Great Basin. Weak and shallow marine layer may still be slow to clear. 

A Detailed Look at June 23rd:

  • Low rip current risk. Water temperature 65-68. Short period west swell, building south swell. Heights 1-3 ft.
  • High temperatures Saturday will be slightly below average. Coastal highs 65-69, normal around 72. Inland highs 74-79, normal around 78. Mountain highs 83-87, normal around 79. Desert highs 104-110, normal around 104.
