A century of climate change in NI

LOOKING at isolated events like this week’s mini-heatwave cannot tell you that much about overall trends for our weather.

Below are Northern Ireland’s average temperatures, decade by decade, in degrees Celcius.

These were collected from 35 weather stations across Northern Ireland and are rounded to one decimal point.
