Marine Weather and Tide Forecast for Dillon Beach, CA

SHORT TERM
(This evening through Sunday)
Issued at 219 PM PDT Sat Jun 21 2025

Winds are building into the afternoon. However, the updated forecast is showing that the widespread wides are going to be weaker overall than the winds experienced yesterday, with only a few exceptions along the immediate coast. Temperatures are mostly around average today as the onshore flow continues and today looks to be the coolest of the next seven. Winds over land reduce into the evening and early tonight, but will stay gusty within the marine environment.

The reduction of winds tonight marks the end of our breezy to gusty pattern and pulls the interior areas out of near critical fire danger. However, a lot of the finer fire fuels (grasses and small plants) have dried and cured in the last few days of dry, sunny and windy conditions, so we urge folks to stay fire weather aware.

LONG TERM
(Sunday night through next Friday)
Issued at 219 PM PDT Sat Jun 21 2025

Winds have been the big focus of the forecast over the last few days, but as the upper level pattern changes, the breezy and gusty conditions are mostly going to be focused over the marine environment into the next work week.

Said change in the upper level pattern with feature the upper level pushing east and slightly south. This will reduce onshore flow into the mid week and weaken winds across the region. Temperatures will increase in the far interior, while the coast and slightly inland areas stay mostly unchanged as marine stratus and fog begin to reestablish in the calmer conditions. As of the current forecast, Thursday looks to be the warmest day of the forecast as the more interior valleys settle into the 90s and some of the warmest of the warm hitting the 100 degree mark, but this won't be widespread and the coastal and slightly inland areas remain in the 60s and 70s.

Something to note, the mid-week model agreement is fair with the current official forecast, but some models hint at the trough pushing farther south and propagate in such a way that could introduce more offshore flow. This will still result in the midweek warm up, but the drier flow could limit the marine layer and coastal cloud cover, making for a much warmer days for the coast. The forecasting team will be keeping an eye on how this continues to develop over the next few forecast updates, be sure to keep checking back in!

FIRE WEATHER
Issued at 221 PM PDT Sat Jun 21 2025

Elevated to near critical fire weather conditions continue today across the interior Central Coast, East Bay Hills, and interior North Bay as another dry day with moderate to poor RH recovery is expected for interior locations and areas of higher elevation, especially for those above the marine layer. Winds will be breezy to gusty as well, peaking around 35 mph, perhaps locally higher at exposed elevations and wind prone gaps. Breezy to gusty winds look to hold through Saturday night. There should be some improvement in humidity into Sunday morning, especially if the marine layer is able to deepen. Widespread critical fire weather conditions are not expected within the district today, although the fire weather threat will increase once again for areas closer to the Central Valley. The fire weather threat will continue to diminish Sunday into the early part of next week with the gusty winds further relaxing, although humidity values in the interior will be slow to rise.
