Distance alone does not establish a climate match. Elevation, coastal exposure, urban shelter and soil can differ; the postal location has no verified garden elevation.
The postal reference point is near 45.571°, -75.761°. At the nearest qualifying ECCC station reference (ANGERS), July is the warmest month on average (19.6°C), while January is the coolest (-11.2°C). This does not measure your garden’s temperature.
Reference monthly means are below freezing in January, February, March, December. This signals a need to assess protected growing, not a calculated planting prohibition. 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 45.571° 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.

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.
Regional advice
Choose a local planting window.
Montréal Botanical Garden · Space for Life
French-language vegetable guidance from Montréal. Its calendar does not cover every Québec climate.
Ask which dates refer to indoor seed starting, direct sowing or transplanting, and whether they cover spring or fall. This referral is not a verified postal-code planting calendar.
Find an official community climate stationThe 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.
- Direct sow in the bed. Use the seed packet for sowing depth and spacing. Check the actual soil temperature and moisture before choosing a sowing day.
- Check outdoor conditions. Cold tolerance varies with crop, variety, plant age and exposure. It does not guarantee germination or survival in frozen soil.
- Plan the next sowing separately. Check local spring or fall advice and the variety’s maturity time before scheduling another batch. Calendar reminders do not establish a safe planting window.
Inspect soil moisture and drainage in the actual bed; rainfall normals cannot tell you whether roots need water today.
These are general growing stages, not local planting dates. Minnesota calendar dates are not transferred to other regions. Read the Extension guide to growing stages.

What this postal area includes
Gatineau Northwest.
A Canadian forward sortation area is the first three characters of a postal code. It can cover several communities, especially outside cities. The representative coordinates may be estimated. Nearby gardens can differ in elevation, shelter, slope and soil.
