There is a funny T shirt which shows the four seasons of weather in Ireland (which includes Belfast), and basically spring summer autumn and winter there is rain! Well, it is not true!
Of course the countryside is a beautiful green thanks to a plentiful supply of water from the clouds above, but overall the majority of days are dry.
Temperatures never fall too low in winter, we are lucky if we receive 2/3 days of snow in a year, and most of the year is pleasantly mild.The hottest days are in July and August but rarely climbing above the mid 20s centrigrade.(alot cooler than Mexico!)
