Well what a terribly cold May that was. Even colder than we predicted. The last few days of May will be pleasant 18 to 21c and the start of June looks set to continue this vein...for a while. 2021 is a year dominated by cold weather in Ireland.
After a warm first few days of June with thundery showers moving up from the South and temperatures in the early 20s the High Pressure weakens and is replaced by cooler unsettled weather again much like May. Probably not quite as cool but 14 to 17 or 18c around most days.
Rainfall will be above normal for the month. Temperatures around average in the West and below average in the East. Sunshine average as much rain will be heavy showers.
Late June might see a warming trend and more sunshine than rain.
