Long Range Weather Forecast for Ireland
A spell of unsettled weather is set to dominate in the coming days, with a largely dry and calm weekend giving way to increasingly wet and windy conditions by Sunday night as Storm Floris approaches. The storm will bring heavy rain, strong winds, and potential disruption nationwide on Monday, particularly in western and northern areas. Conditions will gradually improve from Tuesday, but the outlook remains changeable, with further rain at times and temperatures holding around seasonal norms.
Today:
Largely dry through the afternoon, with some light drizzle developing in the west and northwest later in the day. The best of the sunshine will be in the southeast and east.
Highs: 16–21°C
Winds: Gentle to moderate southwesterly
Sunday:
Morning rain in east Ulster and scattered showers elsewhere will clear eastwards, leaving a mostly dry afternoon. However, widespread and heavy rain will arrive in the northwest by nightfall, with winds strengthening in the west from midnight. Storm Floris will bring increasingly wet and windy conditions nationwide overnight.
Highs: 16–22°C, warmest in the south and southeast, coolest in the northwest

Monday:
A wet and windy start nationwide as a deepening low-pressure system tracks northeast from the west coast toward northern Scotland. Gusts of over 90 km/h are likely along the Atlantic coast, with some exceeding 100 km/h around north Ulster. The heaviest rain will fall in the southwest, west, and north, while the southeast may see drier and calmer intervals. Thunderstorms are possible in the northwest, potentially leading to localised flooding overnight and into the morning. Rain will clear from the west coast by midday, with sunny spells and isolated showers following, though winds will remain blustery.
