Review temperature, precipitation, humidity, and daylight patterns across twelve months.
The annual climate cycle for Upper Tweeddale National Scenic Area is defined through NASA POWER measurements spanning the 1991 to 2020 period. These records provide a representative look at seasonal transitions, capturing month-by-month shifts in mean, minimum, and maximum temperatures alongside precipitation rates and wind speeds. Each data point serves as a long-term average calculated at a fixed geographic coordinate within the Scottish Borders landscape.
