Which way homes face
Streets here run in mixed directions (about 51% east–west, 48% north–south, the rest diagonal or curved), so homes face every way; which side gets the winter sun depends on the street.
Snow and spring melt
In March, about 79% of Altadore's street-side ground still holds 5 cm of snow or more in a typical year (city median 70%), the 22nd snowiest of 133.

Buying a home in Altadore: what winter looks like
If you are looking at homes in Altadore or thinking of living there, expect less winter sun than most of Calgary on the ground along its streets: a median of 0.3 h of direct sun on December 21, against 1.3 h for the city.
Streets in Altadore run in mixed directions, so homes face every way. Which side of a home gets the winter sun, the front with the driveway or the back yard, depends on the street it is on.
Altadore has more snow on the ground in March than most communities and less spring ponding than most in our model. Wherever a driveway or walk sits in shade, snow tends to stay longer, and melt water that runs across it in the day can refreeze at night.
Homes here are older, and older communities often have mature trees, which add shade in winter as well as summer.
At a viewing, check:
- which way the front of the house faces;
- whether the driveway and front steps are in shade around midday;
- where snow has piled up and where melt water has stood or refrozen;
- where the downspouts empty and whether the yard slopes away from the house.
The full list is in buying a house in Calgary in winter.
Within Altadore, two homes on the same street can differ more than Altadore differs from the rest of Calgary. Put the home you are looking at on the map to see its own front yard, back yard and driveway.

How these numbers are made
LandMood follows the sun hour by hour over 1-metre public lidar of the real houses and trees (Natural Resources Canada) with ten years of weather (2016–2025). For this page we sampled the ground along residential streets (boulevards, front yards and driveways as a band, never a single home) and open ground away from buildings, across the whole community. Snow and water are modelled tendencies shown as shares and bands, not measurements.
