Where Rosedale’s numbers come from

Averages over 30 years, not a forecast.

Normals: ECCC’s normals for Burlington Piers, 1991–2020, chosen as the nearest location with a full temperature record.
Other locations: ECCC blanks a month that fails its completeness rule, so the precipitation or snowfall here comes from the next location with all twelve months.
Comparisons: the 2,500-plus towns and neighbourhoods of Canada, each read from its closest normals location; whole cities and reserves aren’t counted.
Not on this page: a sunshine figure (ECCC published none for 1991–2020) and any lapse-rate correction for height, as the town has no elevation here.
