Detailed annual averages for temperature, wind, and precipitation in Cornwall

The Manacles Monthly Climate Normals and Representative Atmospheric Measurement Profiles

The Manacles, a marine protected area in Cornwall, displays distinct long-term atmospheric patterns based on a representative coordinate study. These climate normals utilize 1991 to 2020 NASA POWER data to map monthly fluctuations in average temperature, wind speed, relative humidity, precipitation rates, and daylight duration. The records provide a precise, multi-decade baseline for environmental monitoring rather than current weather forecasting or short-term trends.

The Manacles Annual Climate Normals: Average Monthly Temperature and Precipitation Patterns

Average temperatures in The Manacles range from a low minimum of 3.6 degrees Celsius in February to a peak maximum of 20.42 degrees Celsius in July based on NASA Power climatology records. Average daily precipitation rates move alongside these monthly thermal shifts, showing higher daily moisture levels toward the end and beginning of the year.
