Some hillwalker types assure me this is the most reliable weather site they have found, very accurate hour by hour.

And more good news

from Met Eireann...

"With High Pressure remaining close to Ireland, the weather will continue to stay settled over the weekend and right up to the middle of next week at least. Saturday will still be sunny, but Sunday will tend to be a cloudier day, especially over the northern half of the country. And at times the cloud may be active enough to give some light rain. Highest daytime temperatures over the weekend will range generally from 18 to 22C and the breeze will be light from a northerly direction. It gets warmer again for the start of next week by about a degree every day. Very little breeze at all next week, just local sea-breezes around the coast. Fog will develop at night but will clear quickly during the morning time."
