Southern California’s spring has taken a summerlike detour.

Downtown Los Angeles was 89 degrees (31.6 Celsius) at noon Monday and other locations were into the 90s, well above seasonal normals.

The sudden warm-up is due to high pressure and gusty offshore flow.

The National Weather Service says the heat will be brief, as sea breezes return Tuesday.

California will have a brief spring fling with summerlike temperatures that could produce records.

Highs will reach into the 90s Monday in Southern California due to high pressure and gusty offshore flow.

The Central Coast and parts of the San Francisco Bay Area can expect warming into the 80s.

Forecasters say sea breezes will return Tuesday, but Southern California valleys will remain warm.

Northern portions of the Bay Area will see light rainfall Tuesday as a weak weather system moves through, followed Wednesday by a slightly stronger system with more widespread light rain that could last into Thursday.
