Where Arnold's Cove’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Dunville/Argentia, 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 towns and neighbourhoods of 2,500+ across Canada, each on its nearest normals location, without the city totals or the reserves.
- Not on this page: hours of sunshine, missing from the 1991–2020 normals, and a height correction: the town has no elevation on file.
