Marine Weather and Tide Forecast for Point Arena, CA

SHORT TERM
Issued at 138 PM PDT Wed Jul 15 2026 (This evening through Thursday night)

The marine layer is making a good attempt at returning! However, hot temperatures, very dry conditions, and breezy winds persist across the interior and higher terrain across the region this afternoon.
With full sunshine, temperatures will warm into the 90s to 103 deg F (in the warmest interior spots). These temperatures are slightly cooler than yesterday, yet are up to 10 degrees above seasonal averages (up to 20 degrees above for the higher elevations). Cooler temperatures will persist near the coast as onshore winds prevail.
The aforementioned hot, dry, and windy conditions are creating elevated fire weather conditions across the interior and higher terrain. Please see the Fire Weather Section of the AFD for more information.

The marine layer is forecast to deepen to around 500 feet tonight.
However, cloud cover is a bit more uncertain. There is a 30-50% probability of stratus returning to the coastline and Monterey Bay during the overnight hours and into early Thursday morning. However, any low clouds that do develop will quickly dissipate by mid-to-late morning.

For Thursday afternoon, temperatures generally cool to near seasonal averages for much of the region as onshore winds increase. This will lower HeatRisk to Minor category and bring an end to the warming trend as a mid/upper level trough of low pressure deepens off of the Pacific Northwest coast. Heading into Thursday night, the marine layer is forecast to deepen to around 1,000 feet and increase the potential for low clouds.

LONG TERM
Issued at 138 PM PDT Wed Jul 15 2026 (Friday through next Tuesday)

Onshore winds will persist through much of the upcoming weekend and will allow for the marine layer to deepen and remain steady at around 1,500 feet. Thus, expect temperatures to remain near to slightly below normal for mid July with stratus more likely into the weekend. These low clouds will retreat back to the coast by mid-to- late morning.

Heading into late weekend and early next week, we are keeping an eye on monsoon moisture working its way northward around the Southern Plains' mid/upper level high. However, latest trends indicate the focus for thunderstorms has shifted to the east over the Sierra Nevada Sunday into Monday. That said, still expecting mid-to-high level clouds over the region. This will need to be closely monitored over the coming days as any high based thunderstorms will likely result in dry lightning that can spark wildfires.

AVIATION
(00Z TAFS)
Issued at 453 PM PDT Wed Jul 15 2026

VFR through the forecast except along the coast where low to moderate confidence in a late return of stratus tonight. Breezy winds continue through this evening before easing overnight. Winds generally stay out of the NW through the forecast period with the exception of the North Bay where winds are more southerly. Guidance indicates potential for stratus along the coast tonight but confidence is low to moderate. Satellite is currently clear so if any stratus is able to redevelop tonight it will be late and likely bring IFR to LIFR CIGs .

Vicinity of SFO...VFR. Winds out of the NW with gusts to around 30 knots are expected this afternoon and again tomorrow afternoon.
Guidance shows some potential for stratus to filter into the SF Bay tonight, potentially reaching SFO, but confidence is low.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR with low to moderate confidence in IFR conditions overnight. Breezy W to NW winds continue through this evening before diminishing overnight. Satellite is currently clear but models are indicating some potential for stratus to return tonight. If stratus does return it will be a late return (closer to 10Z) with IFR to LIFR conditions possible.

MARINE
(Tonight through next Monday)
Issued at 453 PM PDT Wed Jul 15 2026

Moderate to strong gusty wind across the coastal waters and bays will produce hazardous conditions for small crafts through much of the week. Gale force gusts are expected along the coastal jet regions of Point Reyes and Point Sur. Moderate to rough seas will prevail through Friday.

FIRE WEATHER
Issued at 138 PM PDT Wed Jul 15 2026

The warm temperatures we have had the past several days and continued warm weather has resulted in fuels rapidly drying this week. Fire weather concerns will remain elevated this afternoon with afternoon relative humidity dropping to between 10-20% across the interior and higher elevations (away from the marine influences), gusty onshore winds, and very dry fuels. This may result in additional fire starts particularly across the interior and higher elevations. These conditions are gradually forecast to improve as the marine layer returns Thursday and deepens into Friday. Unsettled weather is possible late this weekend and into early next week with returning potential for dry thunderstorms and gusty, erratic winds.
However, the focus has shift to the east more over the Sierra Nevada.
