Review long term monthly averages for temperature, precipitation, and regional atmospheric conditions
Annual climatology profile for Ottawa National Forest, providing representative data based on the 1991 to 2020 period. Measurements include monthly average temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours recorded at a representative point within the forest boundaries. These figures present long term climate norms rather than current weather conditions or short term forecasts.

Long-term monthly temperature cycles and average daily precipitation rates across the twelve calendar months
Analyze average temperature bounds, daily precipitation rates, humidity, wind speed, and daylight hours across the year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
