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.

- Recent rain, heat, smoke, fire restrictions, water levels, and afternoon wind can change which route or activity is most comfortable.

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.
