Cooler than usual for the first week of August

A cooling trend will continue through Thursday. Temperatures will drop below seasonal averages with continued morning clouds and fog.

SAN DIEGO — Temperatures took another slip due to onshore flow today. There were fewer 90s as most inland highs peaked in the upper 80s, which is more seasonal for this time of the year.

Marine clouds kept the coast and western valleys mild today. For the rest of the night, a coastal eddy and trough of low pressure will continue to send low clouds and patchy fog in our direction. 

Expect dense fog in spots tonight through Wednesday morning (10 pm to 9 am). There will be a repeat performance Wednesday night through Thursday morning. Reduced visibility will be down to a mile or less at times. 

As the trough over Northern California sags farther south, you can expect our temperatures to slip through Thursday. Afternoon highs will be 5° to 10° below seasonal tomorrow before dipping 5° to 15° on Thursday. 


  • Coastal highs near 71°, normal around 76°
  • Inland highs near 81°, normal around 88°
  • Mountain highs near 83°, normal around 86°
  • Desert highs near 103°, normal around 107°

Additionally, it will be gusty at times for the mountains and the desert as westerly winds pick up tomorrow. Expect gusts in the 30s and 40s possible. Winds look to calm by Thursday.

The trough will weaken by the weekend as high pressure over Arizona expands westward. This will allow temperatures to warm up, but not by much. The low will still be lingering near the California coast. 

Therefore, temperatures for the coast and inland valleys will remain short of seasonal into next week. On the flip side, daytime highs will be seasonal for the mountains and desert. Desert even taking a break from the one-teens.
