You can now see how the temperature has changed over the decades in your region via the new Google Climate Science Center. In County Mayo, that's us, the average annual temperature has, according to NOAA figures, increased by about 1.25 degrees. At this rate, we should reach the Galician average from 1950 very soon or may have already reached it.
From a paper titled 'State of Climate in NW Iberia' August 2011, Climate Research 48(2-3):109-144:
"It is very likely that both maximum and minimum land temperature have increased at the annual scale
since 1974 at a mean rate on the order of 0.5°C/decade. This behaviour is especially marked for
maximum temperature in spring and summer, and for minimum temperature in spring, summer and
autumn."

It's a good thing we are learning how to make wine. We're gonna need it when the heat hits the fan.
