Colne Estuary climate by month: coastal temperature, precipitation, wind, and daylight
Colne Estuary’s representative mean temperature is 4.68 °C in February and 17.36 °C in August. Average daily precipitation measures 1.41 mm in April and 2.36 mm in October, while relative humidity is 91.85% in December and 80.36% in August. These 1991–2020 NASA POWER normals belong to one 25.55 m Essex coordinate, so tidal exposure and local weather can differ among creeks, mudflats, and saltmarshes.

Colne Estuary Weather by Month: Complete Twelve-Month Climate Normals
Evaluating average minimum, mean, and maximum temperature alongside average daily precipitation reveals how atmospheric conditions shift month by month at a representative coordinate. Comparing relative humidity, wind speed, and calculated daylight hours across all twelve records provides a complete climatological baseline for the landscape.
