How Much Rain Does the Texas Hill Country Get
The Texas Hill Country receives about 28 to 36 inches of rain per year on average, but that number hides the real story. Rainfall here is highly inconsistent, seasonal, and location dependent. Some years are drought dry. Others bring intense rain events that drop several inches in a single day. That volatility is one of the defining characteristics of the region.
Most Hill Country rain falls in spring and early fall, driven by Gulf moisture colliding with dry air and frontal systems. May and September are typically the wettest months. Summers can be brutally dry, while winters are usually mild with occasional rain and light freezes. Western Hill Country areas like Kerrville and Junction trend drier, while eastern edges near Dripping Springs and Wimberley tend to see higher totals.
The problem is not just how much rain falls, but how fast it falls. Limestone terrain and shallow soils cannot absorb water quickly. When heavy rain hits, runoff moves fast into creeks and rivers. That is why the Hill Country is known for flash flooding, even during overall dry years. A property can sit in drought conditions for months, then experience flooding from a single storm.
For land and home buyers, rainfall patterns matter more than averages. Water wells, rainwater collection systems, erosion control, septic placement, and floodplain mapping all depend on understanding how rain behaves locally. Two properties ten miles apart can have very different rainfall exposure and flood risk.
The short version is this. The Texas Hill Country does not have predictable rain. It has cycles of drought and deluge, shaped by geology and terrain. Buyers who respect that reality plan better and avoid expensive surprises.
