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.
Your postal reference & climate station
The postal reference point is near 59.867°, -158.600°. In the NASA regional grid reference, July is the warmest month on average (12.8°C), while January is the coolest (-13.7°C). This does not measure your garden’s temperature.
Reference monthly means are below freezing in January, February, March, April, October, November, December. This signals a need to assess protected growing, not a calculated planting prohibition. Check local crop advice alongside this seasonal context. A monthly average cannot identify a safe planting day.
Light at your latitude
At 59.867° 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.
