Blanco gets 10 inches of rain and melted snow a year. August is the wettest month and June the driest. Rain or snow falls on about 57 days a year. Snow covers the ground about 9 days of the year.
About 147 frost-free days a year

Heating and cooling a home in Blanco
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Blanco, 85% of that work is heating and 15% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
