‘June Gloom’ in April Leaves Normally Sunny San Diego Cool and Damp

The atmospheric rivers may have dried up as April began, but coastal San Diego County now has to contend with a heavy marine layer bringing cool weather and drizzle.

“Basically no clearing has occurred in the San Diego coast and valleys, with only partial clearing elsewhere from the lower coastal slopes to the coast,” the National Weather Service said in its Monday afternoon update. “As a result, it was another unseasonably cool day west of the mountains.”

High Clouds, Cooler Weather Predicted for San Diego County

Marginally cooler weather was predicted Sunday for San Diego County, with an expansive shield of high clouds, the National Weather Service said.

The marine layer should be sufficient to generate some sprinkles across the coastal basin Monday night into early Tuesday, and possibly again Tuesday night, with minimal accumulations expected, the NWS said.
