Tracking annual patterns in temperature, precipitation, wind, and daylight from 1991 to 2020
Analyze the consistent atmospheric profile of Réserve nationale de faune des îles de l'Estuaire through long-term monthly normals. These figures represent the 1991 to 2020 climatology at a fixed elevation of 148.88 meters, offering a detailed breakdown of mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and daylight hours. Records provide a foundational understanding of the annual environmental cycle observed at this representative location.

Long term monthly temperature normals and average daily precipitation rates across twelve months
Compare average temperature bounds, precipitation rates, relative humidity, wind speed, and calculated daylight across the calendar 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.
