Review long-term temperature, precipitation, humidity, wind, and daylight averages from 1991 to 2020.
Annual climate cycles at Ukerabagh Island Nature Reserve are characterized by monthly shifts in mean temperature, precipitation rates, and atmospheric humidity. These figures represent long-term averages derived from a representative coordinate at 17.12 meters elevation, providing a standardized look at meteorological patterns over the 1991 to 2020 period. Measurements include average daily precipitation, relative humidity, wind speed, and daylight duration to clarify the environmental context across all twelve months of 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.
Long-term monthly averages reveal thermal, precipitation, wind, and daylight variations across the year.
