A twelve-month profile of temperature, precipitation, wind, and daylight averages
Examine long-term climate measurements for Pembrokeshire Coast National Park based on representative data from 1991 to 2020. These records provide a consistent baseline for comparing monthly temperature, precipitation, relative humidity, wind speed, and daylight hours. Values represent averages at a single point coordinate and serve as a technical reference for local environmental patterns.
