Where Milton’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Burlington Piers from ECCC’s climate data site, the nearest location with every month of temperature.
- 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: a pool of Canadian towns and neighbourhoods of 2,500 or more, read alike; whole cities and reserves stay out of it.
- Not on this page: sunshine, not in ECCC’s 1991–2020 normals, and the effect of the town’s height, for which there is no figure.
