Twelve month analysis of temperature, precipitation, wind, and daylight based on 1991 to 2020 climatology data.
Rochers des Parcs experiences a distinct annual climate rhythm captured through long-term NASA POWER measurements at a representative coordinate. This profile provides the average minimum, mean, and maximum temperatures along with daily precipitation, relative humidity, wind speed, and daylight hours for every month. Such records establish a consistent geographic baseline for atmospheric conditions without representing current weather or localized microclimate variations across the nature reserve.

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.
