Beach Hazards
Warming Trend this Week
Elevated Fire Weather Threat
Planning a trip to the coast over the next few days? Take extra precautions near the water! A long-period southerly swell, generated by distant tropical cyclones in the Eastern Pacific, is pushing toward our coastline. This swell will bring elevated surf and hazardous ocean conditions through mid-week. Here is what you need to know: What: Increased risk of sneaker waves and strong rip currents, with breaking waves up to 10 feet expected at south and southwest-facing beaches and breakpoints. Where: Pacific Coast beaches across the San Francisco Bay Area and Central Coast. When: Now active through Wednesday Afternoon. Beach Safety Tips: 🪨 Stay Off Infrastructure: Keep off rock outcrops, jetties, piers, and breakwaters—sudden large waves can easily knock you off your feet. 🏊 Avoid Hazardous Surf: Remain out of the water. 👁️ Stay Alert: Never turn your back on the ocean! Always keep a close watch on children and pets near the water's edge.

Warm to hot conditions are forecast this week as high pressure builds in from the Pacific Southwest. Highs temperatures will have at least a 40-70% chance of being above normal with temperatures away from the coast in the 80s and 90s. Far interior regions will likely eclipse 100 degrees, especially during the later half of the week. Coastal locations will remain in the 60s. Be sure to hydrate by drinking plenty of water, take frequent breaks and shift outdoor activity to cooler times of the day. NEVER leave children or pets in unattended vehciles.

Seasonably elevated conditions with rapid rates of spread possible on any wind-and-terrain aligned starts in receptive vegetation. Afternoon RH will range between 10 and 30 percent, with morning RH recovering between 25 and 50 percent (mainly at elevations above 2,000 feet). Be sure to avoid burning debris or leaving campfires unattended, avoid using equipment that could create a spark. Properly extinguish and discard cigarette butts and secure tow chains to avoid dragging! The fire weather threat will be greatest through mid-week, but may persist through next weekend, especially across the interior Central Coast.
