Brief June Heat
Your forecast for Monterey, Santa Cruz, San Benito, and southern Santa Clara Counties…
Big changes are coming for your Tuesday! Dry air is moving into the region overnight as high pressure builds in from the west. This dry air will prevent low cloud development and also allow for cooler morning lows, especially in low areas. However, as the early June sun rises, the dryer air will be much easier to heat! The ridge comes along with a much warmer air mass and combined with the dryer air will mean for a 10-15ºF jump in temperatures for most Tuesday afternoon! Those that are especially heat sensitive may have trouble dealing with this change in temperature. The ridge will center over us on Wednesday with most areas seeing their hottest temperatures of the year so far. Light onshore flow will keep temps down on the coast, but they may still reach 10ºF above normal.
AIR QUALITY: Good
Overnight: Mostly clear with a few passing high clouds and perhaps a low cloud or two. Expect lows in the upper 40s to low 50s for most locations.
Tuesday: Mostly sunny with just a few high clouds passing through. Much warmer, with coastal highs in the upper 60s to mid 80s—warmest on the north side of the bay—and mid 80s to upper 90s inland. Gusty northwesterly onshore and up-valley winds developing late in the day, which will introduce some temperature relief to coastal areas.
Wednesday: Mostly clear and warmer into the morning hours then mostly sunny during the day with a few high clouds passing through. Coastal highs in the 70s-80s with upper 80s to low 100s inland. A light sea breeze will offer some relief on the beaches late in the day and some fog may be possible along the direct coast late.
**HEAT ADVISORY**
…for the Gabilan Range, Cholame Hills, and southern inland valleys of Monterey County, the mountains and higher elevation valleys of San Benito County, the Santa Clara Valley and the Diablo Range in Santa Clara County in effect from 8AM Wednesday until midnight Thursday.
*Daytime temperatures in the 90s to near 100 degrees, farthest inland 100 to 103 degrees expected. Overnight temperatures lowering to the 60s.
*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.
*Beach Hazards Statement*
…for the immediate coast of Monterey County from Wednesday morning through Thursday evening.
*A moderate-rough NW swell will create large breaking waves of 15-20 ft and an increased risk for sneaker waves.
*Large waves can sweep across beaches without warning.
*There are two hazards to be aware of, high surf and sneaker waves. Large breaking waves create a hazardous surf zone with breaking waves of 15-20 ft, especially along steep beaches. Sneaker waves can run over 100 ft up a dry beach, pulling people in into the water from rocks, jetties, and beaches.
Inexperienced swimmers should stay out of the water. Observe the ocean for 20 minutes before relaxing on the beach. The hot weather inland will lead to more people visiting the beach this
week. Know where lifeguards are, obey their instructions, and never turn your back on the ocean!
Extended: Deeper onshore flow will cool coastal areas on Thursday mark the return of low clouds while inland areas remain sunny & hot. Coastal temps cool down into the 60s for most areas Thu/Fri with inland temps slowly cooling. By the weekend, partly cloudy, seasonable weather can be expected.
