SAN DIEGO — Wednesday afternoon high temperatures will be below seasonal average.

  • Coastal highs 67°-73°, normal around 72°.
  • Inland highs 72°-79°, normal around 85°.
  • Mountain highs 73°-83°, normal around 81°.
  • Desert highs 96°-102°, normal around 105°.

At the beach, the rip current risk is low with water temperature 64°-66°. Waves are 2'-3'. There is a moderate south swell and a minor west swell in the water.

Some patchy drizzle is still possible, but less widespread Wednesday morning. The clouds are still fully extended inland but clearing should be a little faster, with more sunshine for the coast.

The UV index will peak at 10 Wednesday, which is considered very high. Sun protection is needed, 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.


Temperatures will begin to warm up towards seasonal average, due to weaker onshore flow. Summer temperatures finally make their way into the region. 

A trough over the Pacific Northwest will keep excessively hot temperatures at bay. Temperatures will continue to slowly warm through the weekend into early next week. The placement of that trough will determine whether or not we can get some rain this weekend, from some tropical moisture. This will be something to watch in the coming days.
