Where Port Coquitlam’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Pitt Meadows, 1991–2020, chosen as the nearest location with a full temperature record.
- Other locations: a location missing months of precipitation or snow is filled from the nearest that has them all, never mixed month by month.
- Comparisons: all Canadian places of 2,500 or more except city totals and reserves, each read the same way.
- Not on this page: sunshine, which none of ECCC’s 450 locations publishes for 1991–2020, and the town’s own height above sea level, so no figure is adjusted for altitude.
