Your seasonal context
Understand the place before the date.
The 78618 area uses a representative location near 30.461°, -99.171°. In the nearby historical climate grid, August is the warmest month on average (28.3°C), while January is the coolest (8.2°C). May has the highest mean daily precipitation (3.29 mm).
No monthly mean in this grid is below freezing. Individual cold nights can still occur; this does not establish a frost-free season. Use these seasonal differences to frame your questions for a local gardening adviser.
Light at your latitude
At 30.461° N, the length of the day changes independently of temperature. Compare the middle of three seasons when planning your garden.
Geometric daylight estimate from latitude and solar declination, rounded to 0.1 hour. This is time above a flat horizon, excluding atmospheric refraction, hills, buildings and cloud cover. It is not the direct-sun exposure of your bed. About solar-position calculations.

Distances use GeoNames representative postal coordinates, which may be estimated; they are not driving distances. Nearby areas often share one NASA POWER grid cell, so identical climate values are expected. Differences shown here describe the climate grids, not a measured difference between individual gardens.
