Daytime highs and lows on this page are 1991-2020 averages. Cozumel: no weather station within 30 km at a similar height, so lows are ERA5 point values for 2023-2024, corrected month by month by NASA POWER's difference between those two years and 1991-2020, and highs are the uncorrected ERA5 values, which tested closer to station normals; rain is the CHELSA 1981-2010 climatology on a 1 km grid. Toronto: station normals from Toronto City (WMO); rain is the CHELSA 1981-2010 climatology on a 1 km grid. Sunlight vs a clear sky is NASA POWER's long-term average of the solar energy reaching the ground as a share of a cloudless day; it compares cloudiness and is not a count of sunshine hours. Toronto stands in for Canada here; other cities have their own climate tables.
