Long Range Weather Forecast For Ireland (13 August 2021)


TRENDS for the week of 13 to 19 Aug 2021 --

-- Temperatures will be on a slowly rising trend and might average 1.5 deg above normal.

-- Rainfall could be near normal in some parts of the inland southwest, otherwise closer to 50% of normal, and most of this will occur on the weekend with generally dry weather setting in next week.

-- Sunshine will improve back towards normal values.

-- The trend with wind speed will be towards moderate and then light winds through the period.


TODAY will see scattered showers mainly in the west and north, and long dry intervals elsewhere with cloudy skies sometimes breaking to partly cloudy, highs near 18 C.

TONIGHT will bring increasing cloud and lows near 10 C, rain developing near west Munster coastlines and moving slowly inland there.

SATURDAY will start out partly cloudy to sunny in some eastern and northern counties. Cloud and rain will be moving into west Munster with some heavier bursts expected around mid-day around Clare and Limerick, Tipps. Local amounts of 20 mm are possible. This rain will spread with lighter amounts into much of Connacht, the midlands, and east Munster, eventually reaching some parts of Leinster, but towards evening the rain will be fragmenting to showers. Some parts of Ulster could remain dry if rather cloudy. Highs 17 to 19 C.

TONIGHT the remnants of the showery rainfall band will edge southeast into south Leinster and east Munster where a further 5-10 mm is possible. Skies will become partly cloudy further north. Lows 10 to 13 C.

SUNDAY will be partly cloudy with isolated showers, highs 18 to 21 C.

MONDAY will be breezy and rather cool with isolated showers, lows near 8 C and highs near 17 C.

TUESDAY and WEDNESDAY are looking fairly cloudy with drizzle in low marine cloud layers near some coasts, but variable cloud inland, rather warm away from the coastlines, lows near 12 C and highs 18 to 21 C.

By THURSDAY a partly cloudy to sunny regime will develop and temperatures may warm up as high as the 23-25 C range for a few days. It looks at present like this good spell of weather might last about four days through the weekend of 21st-22nd, then it would be back to the more unsettled pattern of this past week with temperatures falling back into the 15-18 C range.
