Bay Area residents should prepare for a mixed bag of weather conditions this week, according to the latest forecast from the National Weather Service in San Francisco, CA. The weather outlook indicates warm and dry conditions through midweek, with hazardous beach and boating conditions. However, the respite may be short-lived as there's a chance for a few showers later in the week, and a pattern change is on the horizon for the weekend, promising several opportunities for rain and weather.
Today's temperatures in the region kicked off with a chill, as skies are expected to clear, leading to a mostly sunny afternoon. Highs in the valleys could reach the mid to upper 60s; in southern Monterey County, even low to mid-70s are possible. Coastal areas and mountain regions are looking at mid-50s to mid-60s. "Much of the Bay Area and Central Coast is covered with 'minor' HeatRisk," the National Weather Service warned, alerting those sensitive to heat to stay cool and hydrated.
Come nightfall, the clear skies will likely lead to further radiational cooling, putting low temperatures for Tuesday night into Wednesday morning in the low to mid-40s for many valleys, with potential dips into the upper 30s for some areas. Heading towards Wednesday, the warmth is expected to climb, with the mercury potentially tipping into the high 70s in valleys like Salinas and Santa Clara, signaling unseasonably warm conditions for this time of year.
The aviation sector is also impacted, with mixed skies and patchy fog presenting challenges for Bay Area airports. High confidence in LIFR/IFR conditions persists through sunrise, primarily for North Bay terminals, with a transition to VFR expected as the day progresses. According to the National Weather Service, light to breezy onshore winds are forecasted for the area.
For those heading out to sea, the weather service has issued advisories cautioning mariners about fresh northwest breezes and moderate swells, which could create rough seas and hazardous conditions for smaller crafts. Wave heights are expected to elevate to 12 to 15 feet; even larger waves are predicted for the northern outer waters. Beachgoers aren't in the clear either, as an increased risk for sneaker waves and rip currents is anticipated along the coastline due to the arrival of a long period of northwest swell continuing through Wednesday morning, culminating in 15 to 18-foot breakers along west and northwest-facing beaches.
