The heat wave that has gripped Southern California will begin to subside Sunday, but a heat advisory remains in effect through 8 p.m. for the inland valleys.

The National Weather Service office in San Diego said the warm and dry weather will continued through Tuesday with a slight cooling each day. High temperatures will be close to the average by Wednesday.

At noon Saturday, temperatures of 100 degrees were recorded in Escondido, 97 degrees in Fallbrook and Jamul, 96 degrees in Ramona and at Marine Corps Air Station Miramar, 89 degrees in San Diego and 71 degrees on Mount Laguna, according to the weather service.

“Consecutive days of hot weather will increase heat stress on animals and humans, making it hard for the body to keep cool,” according to the weather service. “Without precautions, even healthy adults could experience heat stress and illness.”

Ways to avoid heat-related illness include rescheduling strenuous outdoor activities to early morning and evening hours; wearing light, loose fitting clothing; taking frequent breaks in shaded or air-conditioned areas; and drinking plenty of water.

Forecasters said those going to the beaches in hopes of some respite from the heat would have to deal with strong rip currents and higher than average surf that could lead to dangerous swimming conditions, especially for those with little experience in the water. A beach hazards statement will remain in effect through Sunday night.

The highest surf — 3- to 5-foot waves with set to 6 feet — was expected on south and southwest facing beaches.
