Your seasonal context
Understand the place before the date.
The 95925 area uses a representative location near 39.468°, -121.194°. In the nearby historical climate grid, July is the warmest month on average (25.8°C), while December is the coolest (5.3°C). December has the highest mean daily precipitation (6.02 mm).
No monthly mean in this grid is below freezing. Individual cold nights can still occur; this does not establish a frost-free season. Tomatoes are frost sensitive: confirm local frost guidance and suitable soil conditions before sowing or transplanting.
Light at your latitude
At 39.468° 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 tomatoes a considered start.
Check the root ball while the plant settles in. Keep moisture consistent without leaving the roots in saturated soil, and put supports in place while plants are small.
- Choose a variety suited to your available space and compare its days to maturity with local seasonal guidance.
- Harden off established transplants before planting outdoors.
- Confirm a suitable frost-free window with your local forecast and gardening adviser.
- Inspect soil moisture and drainage in the actual bed. Regional rainfall averages cannot tell you whether roots need water today.

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.
