First day of summer to see peak of heat wave

SAN DIEGO (KUSI) — Although what felt like summer heat started over the weekend, Monday marks the official first day of the season and temperatures are expected to be high. A National Weather Service excessive heat warning remains in effect as a heat wave continues to hit San Diego.

Monday is expected to see the highest temperatures of the heat wave. Chula Vista, Escondido, Ramona, Alpine and El Cajon were just a few areas to see record-breaking temperatures Sunday. Warm temperatures lasted overnight and will continue for most of the day Monday.

An excessive heat warning issued by the NWS remains in effects for mountains, valleys and deserts until 8 p.m. Wednesday. An excessive heat advisory for coastal areas will expire Monday night.

Winds are expected to be gusty beginning Monday afternoon, especially in coastal areas. Gusts will reach 15 to 30 miles per hour. 

The ridge of high pressure causing the increase in temperatures will hang over San Diego until Friday. But beginning Tuesday, it will start to weaken allowing clouds to move in and defend San Diego from the heat.

Monday’s high temperatures are expected to be 86 degrees along the coast, 106 degrees inland, 90 degrees in the mountains and 118 for the deserts.
