Beach Hazards Statement
Beach Hazards Statement issued November 13 at 3:44AM PST until November 13 at 6:00PM PST by NWS San Francisco CA (Expires: November 13, 2026 8:00 pm)
Show Alert Details & Instructions
Description:
* WHAT...For the Beach Hazards Statement, An increased risk for
sneaker waves and strong rip currents with breaking waves of
15 to 20 ft expected. For the High Surf Warning, Dangerously
large breaking waves of 25 to 35 ft, with occasional sets of
40 to 50 ft at favored breakpoints. For the Coastal Flood
Advisory, large breaking waves will run up beaches and crash
over seawalls, inundating adjacent, low-lying infrastructure.
* WHERE...Coastal North Bay Including Point Reyes National
Seashore, San Francisco Peninsula Coast and Northern Monterey
Bay.
* WHEN...For the Beach Hazards Statement, through this afternoon.
For the High Surf Warning, from 6 PM today to 4 AM PST Sunday.
For the Coastal Flood Advisory, from midnight tonight to 6 PM
PST Saturday.
* IMPACTS...High tides will result in flooding of low-lying
infrastructure, isolated road closures, and coastal erosion.
Rising tides will bring water and waves farther up the beach
than normal, restricting escape from beaches and coastal
areas. Dangerously large breaking waves can overpower
swimmers, pulling people into the sea from beaches, jetties,
and rocks resulting in significant physical injury and
increasing the risk of drowning. Waves can sweep across the
shoreline without warning, pulling people into the sea from
beaches, jetties, and rocks.
* ADDITIONAL DETAILS...The Coastal Flood Advisory on Saturday is
specifically for the Pacific Coast, where large breaking waves
will spill over sea walls and run up beaches onto adjacent
infrastructure.
Instructions:
If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.
Everyone should remain out of the water due to life-threatening
surf conditions. Stay off of jetties, piers, and other waterside
infrastructure.
Stay off of jetties, piers, rocks, and other waterside
infrastructure. Remain out of the water to avoid hazardous surf
and NEVER turn your back on the ocean. Monitor local weather,

About Muir Woods
Muir Woods is an outdoor-planning page for Muir Woods and its immediate approach corridor. It has a distinct purpose centered on reservation timing, shaded redwood trails, rain, parking, and approach roads, with the forecast used to choose the safest and most comfortable version of the day.
Make the Most of a Muir Woods Day
Start by comparing conditions across Mill Valley, Mount Tamalpais, and the rest of the coverage area. Choose among hiking, biking, outdoor events based on wind, precipitation, temperature, visibility, water or trail conditions, road access, smoke, and available daylight.
Weather Tips for Muir Woods
- Conditions around Muir Woods and its immediate approach corridor can differ sharply from nearby towns; reservation timing, shaded redwood trails, rain, parking, and approach roads are the main planning variables.
- For biking, compare wind, pavement or trail surface, heat, visibility, traffic, smoke, and recent rain before choosing distance and exposure.
- Recent rain, heat, smoke, fire restrictions, water levels, and afternoon wind can change which route or activity is most comfortable.
- Air quality and wildfire smoke can shift quickly; shorten strenuous plans when visibility or breathing conditions worsen.

7-Day Forecast for Muir Woods
Muir Woods Weather by Season
Winter
At Muir Woods, winter rain can make forest and ridge trails muddy or slick, while wind and fog reduce visibility on exposed roads. Strong systems may bring downed limbs, drainage issues, and temporary trail closures.
Spring
Around Muir Woods and its immediate approach corridor, spring is green and often excellent for hiking and biking between showers. Fog can sit below sunny ridges, but late rain and saturated trail surfaces still require flexible route choices.
Summer
For reservation timing, shaded redwood trails, rain, parking, and approach roads, marine layer keeps some slopes cool while inland ridges heat rapidly above the fog. Afternoon wind, dry vegetation, crowds, and fire restrictions become increasingly important.
Fall
Near Mill Valley and the surrounding area, early fall can be warm and clear, but offshore wind and wildfire risk may close trails or roads. The first rain can improve fire conditions while making steep paths slick.
Key Climate Data Points
- Warmest months: August through October on sunnier ridges.
- Coolest months: December through February.
- Wettest season: November through March.
- Driest season: July through September.
- Best outdoor window: Spring and early fall for ridge hikes, biking, and camping.
