Your seasonal context
Understand the place before the date.
The V4Z area uses a representative location near 49.079°, -121.610°. In the nearby historical climate grid, August is the warmest month on average (16.0°C), while December is the coolest (-1.9°C). November has the highest mean daily precipitation (9.31 mm).
Monthly mean temperatures are below freezing in January, February, December. Outdoor planting during those months needs a separate protected-growing assessment. Leaf lettuce 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 49.079° 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 leaf lettuce a considered start.
Sow a manageable amount and label the variety. Record what germinates well in your own garden so the next small sowing can be based on experience.
- 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.

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.
