No measurable rain in the window. Over the tracked history, Bolinas Ridge has been rideable on 10 of the last 10 days. Daily trail markers are representative daytime outlooks. Weather is one input. The rideability verdict also accounts for soil, terrain, canopy, and drying time.

Why Bolinas Ridge dries this way

Bolinas Ridge sits in the Bay Area, CA area, on loam soil that drains well over terrain that holds water and dries slowly. Heavy tree cover holds the damp in, so it stays wet longer than the sky overhead would suggest. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour. The terrain here is gentle (a 2° average grade at 866 ft) and drains slowly enough that low spots stay soft after a storm, while the NW-facing aspect keeps the dirt shaded for much of the day, so moisture lingers after rain and snow is slow to clear. Trails on the map here include Happersberger Trail, Oat Hill Fire Road and PumpkinTrail.

How these factors affect drying

SoilLoam

Loam balances drainage with water retention, so it typically takes a day or two to dry after meaningful rain.

CanopyDense 77%

Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.

TerrainHolds water

Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.

Can you ride Bolinas Ridge after rain?

Usually yes, once the surface has had time to firm up, typically a day or two after meaningful rain. Rather than counting days, check the live verdict above: it already accounts for how much rain actually fell here and how fast this exact ground, with its slope and tree cover, gives back a firm, dry surface.

Does Bolinas Ridge get snow in winter?

Rarely. Bolinas Ridge sits low and mild enough (around 866 ft) that snow seldom affects riding; conditions are driven by rain and drying. Loam still flags FROZEN on the rare freeze.

What trails are at Bolinas Ridge?

What's the terrain and elevation like at Bolinas Ridge?

Bolinas Ridge sits at roughly 866 feet, faces mostly NW, and averages a 2° grade with about 77% tree cover. That makes it a shady network that holds moisture longer than sunnier neighbors, and the gentle grade means it leaves low spots soft after storms. Loam models this exact ground against live weather rather than using one regional forecast.

When is the best time of year to ride Bolinas Ridge?

There is no real off-season at Bolinas Ridge: snow rarely interferes, so good days come down to rain and how fast the dirt dries. Its shady aspect means it needs longer after storms than sunnier networks nearby. The live verdict above reflects today.
