Everything below is collected in one spot so you do not have to cross-check Edmonton climate: monthly averages by hand. The gap between Jan and Jul is 28.0 C here: -10.2 C against 17.8 C. Precipitation peaks in Jul (3.08 mm/day) and bottoms out in Dec (0.60 mm/day), so a 5.1x difference between the two. Taken together that is roughly 518 mm of rain a year for the grid cell. The build runs on a schedule and caches the last good response, so the numbers stay put even when the upstream API is having a bad day. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Edmonton climate table shows
Values are multi-decadal climatological averages for the 53.5501, -113.4687 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
How much rain is 3.08 mm/day in a month?
Rain is recorded as a daily mean, so 3.08 mm/day is roughly 94 mm across a 30-day month.
