National Forecast

18 August 2017 22:42


Cool and breezy, with clear spells and scattered showers with most of these in Atlantic coastal counties before dawn. Lowest temperatures of 9 to 12 degrees in fresh to strong and gusty west or northwest winds.


Some scattered showers on Saturday, mainly in the morning, but a lot of dry weather overall, with some bright or sunny spells at times. Breezy for a time, with fresh northwest breezes persisting into the early afternoon, but these easing later and becoming southwesterly. Top temperatures 15 to 18 C.


OUTLOOK: There is a high degree of uncertainty in the outlook as a consequence of ex-Hurricane Gert moving towards north-west Europe, therefore forecast details for Ireland are likely to change day to day. However, in general our weather looks set to remain changeable and rather unsettled. High rainfall totals are likely in places late Sunday and on Monday, especially across western and northwestern counties with the risk of localised spot flooding.

SATURDAY NIGHT: A dry start across much of the country on Saturday night but outbreaks of rain will develop in the southwest later and extend gradually northeast, reaching much of Munster and Connacht by dawn. Hill and coastal fog too. Lowest temperatures 8 to 12 degrees, coolest in the north and east.

SUNDAY: Showery rain will extend northwards on Sunday, turning heavy and locally thundery at times. However, parts of Ulster may hold dry until evening time. Becoming humid in the south and a few sunny spells may break through here later. Low cloud and fog will affect some coasts and hills. Highest temperatures of 16 to 20 degrees – warmest in Munster. Winds will be light to moderate, variable in direction.

MONDAY: Further outbreaks of rain on Monday, again with the risk of heavy and thundery bursts. Current indications suggest the rain will be heaviest and most persistent in the west and northwest with the risk of spot flooding here. However, the rain will be rather fragmented and decent dry periods are likely to develop in the south and east at times. Highest temperatures of 17 to 22 degrees, but possibly higher where the afternoon sun breaks through.

TUESDAY: The latest guidance indicates Tuesday will be a warm and humid day with a mix of sunny interludes and scattered heavy showers. Top temperatures on Tuesday will range 18 to 24 degrees in light southerly breezes.
