Warm And Humid Spell Ahead For Cork As Continental Air Moves In

Met Éireann is forecasting warm or very warm weather developing widely over the coming week as Continental air moves in across the country. Cork sits on the milder edge of the national picture rather than at the very top of it, with chart guidance pointing to the low to mid twenties in Cork City by midweek.

The national forecast, issued at 12:30pm on 08 August 2026, gives a dry afternoon today with a mix of cloud and warm spells of sunshine. Highs of 19 to 24 degrees are expected, warmest in the southeast, in light to moderate southwest breezes. ECMWF guidance for the Cork City point puts this afternoon closer to 19 to 21 degrees, with gusts staying below roughly 35 km/h and no significant wind hazard indicated.

Tonight brings some patchy rain and drizzle, although Met Éireann notes many southern counties will remain fully dry. There will be some mist and hill fog too. It will be very mild and humid, with overnight minima holding between 13 and 16 degrees in mostly light southwesterly breezes.

Sunday will be mostly dry with a mix of cloud and warm spells of sunshine. Patchy drizzle will develop during the evening hours with a few sharp bursts possible. Top temperatures of 19 to 26 degrees are forecast, warmest for the southeast, in moderate west to southwest breezes. For Cork City, the ECMWF point guidance is nearer 21 to 23 degrees during the afternoon.

Sunday night sees well scattered showers at first, but overall dry and calm conditions under clearing skies, with lowest temperatures of 9 to 13 degrees.

Monday will be dry with a mix of cloud and sunshine, warmest across Munster and Leinster, with top temperatures of 17 to 24 degrees in just light westerly breezes. Cork City is likely to sit around 19 to 21 degrees on current chart guidance, with winds falling exceptionally light.

Tuesday is when the warming trend takes hold properly. Met Éireann expects long spells of summer sunshine and top temperatures of 22 to 26 degrees in just light southeast breezes.

Wednesday will be very warm and humid in a light to moderate southerly breeze, with a mix of cloud and sunshine and some showery outbreaks of rain gradually moving in from the Atlantic. Some east and southeast areas will stay fully dry. Top temperatures of 22 to 28 degrees are forecast, warmest for Leinster, with the Cork City signal closer to 23 to 24 degrees and only small rainfall totals indicated.

Thursday and Friday will stay rather warm for southern and eastern areas while turning fresher elsewhere, with a fair amount of dry weather and just isolated showers. Thursday currently looks like the standout day for Cork, with ECMWF Control touching about 25 degrees at the Cork City point and the central ensemble range running from roughly 22 to 25 degrees. Friday carries considerably more uncertainty, with the deterministic run near 23 to 24 degrees but the ensemble spread widening to between 19 and 23 degrees.

Nights will turn noticeably muggy as the week goes on, with the Cork City guidance showing overnight minima holding around 17 to 20 degrees from Wednesday through Friday.

Met Éireann has the pollen forecast at medium and the solar UV index at moderate to high. Further detail is available on the pollen forecast and UV index pages.

For drivers, there is no significant wind disruption indicated across the week. Allow instead for locally wet roads and briefly reduced visibility from Wednesday onwards, particularly on Friday, when the rainfall signal is at its least certain.
