Over the tracked history, Hill Country State Natural Area 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 Hill Country State Natural Area dries this way

Hill Country State Natural Area sits in the San Antonio & Hill Country, TX area, on rocky clay soil that drains fast 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. The terrain here is nearly flat (a 0.9° average grade at 1,516 ft) and lets water sit, so the flat stretches are the last to firm up, while the NW-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture.

How these factors affect drying

SoilRocky clay

About 53% of this ground is rock fragments, so water runs through it faster than the soil type alone suggests. It dries quicker than plain clay. The soil type here is classified, but the exact drying speed is modeled from that classification rather than measured directly at this spot.

CanopyPartial 34%

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.
