Your seasonal context
Understand the place before the date.
The 77243 area uses a representative location near 29.834°, -95.434°. In the nearby historical climate grid, August is the warmest month on average (29.0°C), while January is the coolest (10.3°C). June has the highest mean daily precipitation (4.20 mm).
No monthly mean in this grid is below freezing. Individual cold nights can still occur; this does not establish a frost-free season. Spinach tolerate some cold, but variety, plant age and exposure still matter. A monthly average cannot identify a safe planting day.
Light at your latitude
At 29.834° 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.
The growing checklist
Give spinach a considered start.
Read the variety guidance for germination conditions. If a hot seedbed gives poor emergence, reassess the conditions before sowing the entire packet again.
- Choose a variety suited to your available space and compare its days to maturity with local seasonal guidance.
- Prepare the seedbed and follow the packet depth and spacing.
- Check the variety’s temperature guidance. Cold tolerance does not mean every seedling survives a freeze.
- Inspect soil moisture and drainage in the actual bed. Regional rainfall averages cannot tell you whether roots need water today.
Read University of Minnesota Extension vegetable guidance. Its crop-care principles are useful here; its Minnesota planting dates are not applied to Texas.
One small next step
Make a date to check your garden.
Choose your own reminder date after checking local advice. This is a personal planning prompt, not a calculated planting recommendation.
