Over the tracked history, Mount Penn has been rideable on 7 of the last 10 days, under a caution advisory on 2, and too wet to ride on 1. Daily trail markers are representative daytime outlooks. Weather is one input. The rideability verdict also accounts for soil, terrain, canopy, and drying time.

Why Mount Penn dries this way

Mount Penn sits in the Lancaster & Lebanon, PA area, on loam soil that drains well over terrain that holds water and dries slowly. 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. At 240 ft, Mount Penn rides NE-facing ground that catches morning sun, so the surface firms up earlier in the day; the nearly flat grade, around 1.8° on average, lets water sit, so the flat stretches are the last to firm up.

SoilLoam

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

CanopyPartial 58%

A mix of sun and shade. Conditions vary across the network, with open sections drying faster than covered ones.

TerrainHolds water

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

Usually yes, once the surface has had time to firm up, typically a day or two after meaningful rain.

Mount Penn sits at roughly 240 feet, faces mostly NE, and averages a 1.8° grade with about 58% tree cover.

Loam models this exact ground against live weather rather than using one regional forecast.

When is the best time of year to ride Mount Penn?

There is no real off-season at Mount Penn: snow rarely interferes, so good days come down to rain and how fast the dirt dries. The live verdict above reflects today.
