The Heat Is On!

Your forecast for Monterey, Santa Cruz, San Benito, and southern Santa Clara Counties…

Get ready! Temps are ramping up with a heat advisory already issued for Saturday! A ridge of high pressure begins to build back into the Central Coast just in time for the first official weekend of summer. This will send temperatures back upward and eliminate coastal clouds come Friday afternoon. Get the sunscreen out and lots of water! Prepare for warm daytime highs along the coast, and hot, dry conditions inland- with the return of those triple digits for far interior locations. Make those preparations early to stay cool and hydrated. Extended forecast below.


Overnight: Low clouds will thicken ahead of sunset, filling valleys overnight. Mostly cloudy along the coast, partly cloudy inland. Coastal lows will be in the upper 40s to low 50s, with interior locations in the 40s. Patchy fog possible closer to dawn, mainly on mountain passes.

Saturday: Temps will be climbing into the 60s and some 70s at coast with sunshine, and a moderate heat risk inland as temps rise into the 90s and low 100s in many locations. Heat Advisory for inland all day.

… for interior mountains and valleys of Monterey, San Benito, and Santa Clara Counties, including areas as Santa Clara Valley, Eastern Santa Clara Hills, Mountains of San Benito and Southern Salinas Valley, Santa Lucia Mountains.

*In effect from 11am to 10pm Saturday.  

*High temperatures in the upper 90s to mid-100s expected.

*Hot temperatures may cause heat illnesses to occur.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.

Sunday: Noticeably cooler with temps more seasonal for the afternoon highs with low to mid 60s coastal and 70s and 80s inland with a few 90s. Mix of sun and clouds at coast with sunshine inland and breezy.

Extended: Heading out of the weekend the ridge will weaken, giving the Central Coast a gradual cool down into early next week where temperatures will return to near seasonable. We'll stay in this pattern through mid-week. Some models are indicating a possible cool down late next week with some troughing occurring. That has yet to be determined so keep watching the forecast.
