The five forecast numbers below highlight the key parameters for Monday. One pattern stands out: every major source agrees on a very warm, mostly dry day with light winds – but the exact degree of cloud and late‑day drizzle remains open.

What does meteorology say for tomorrow?

Dublin forecast for tomorrow

Met Éireann’s Dublin forecast, issued at 05:30 UTC on 24 May 2026, calls for a dry, sunny and very warm day with highest temperatures of 25 to 27 degrees and a light southerly or variable breeze (Met Éireann). The Met Office, the UK’s official weather authority, lists Monday’s high at 27°C, closely matching the Irish service (Met Office). AccuWeather’s 10‑day forecast panel shows a 2% precipitation chance and a clear night ahead (AccuWeather).

• Daytime high: 25–27°C (Met Éireann, Met Office)
• Night low: 7–12°C (RTÉ Weather, Ireland’s public broadcaster)
• Wind: light southerly (~11 km/h) (Met Éireann)
• Sunrise / sunset: sunrise 05:10, sunset 21:30 (approximate for Dublin late May)

The catch: the three major sources agree on a warm, dry Monday, but AccuWeather’s 2% precipitation figure is the most precise, while Met Éireann’s mention of “patches of drizzle” for Monday night leaves a small window for evening dampness.

Cork forecast for tomorrow

While this article focuses on Dublin, Cork (Munster) is expected to be slightly cooler with highs of 23–25°C, a light south breeze, and a higher chance of mist clearing later in the morning (RTÉ Weather).

National overview

Across Ireland, Monday will be warm and mostly dry. The southeast (Wexford, Waterford) may see the highest temperatures, while the northwest (Donegal) could be a few degrees cooler. Mist and fog should clear from most areas by mid‑morning, though some patches may linger near the south coast (RTÉ Weather).

The implication: Monday’s exceptional warmth is a short-lived peak, so prioritizing outdoor plans early in the week makes sense.

What is the weather in Dublin tomorrow?

Hourly breakdown

From early morning until mid‑afternoon, Dublin will see clear skies. AccuWeather’s current conditions at 75°F (24°C) with a RealFeel of 77°F (25°C) suggest the morning starts warm and stays that way (AccuWeather). Wind remains light from the west‑southwest at about 7 mph (11 km/h), gusting to 13 mph (21 km/h).

• Morning (8 AM – 12 PM): sunny, 15–22°C
• Afternoon (12 PM – 6 PM): sunny, 25–27°C, light wind
• Evening (6 PM – 10 PM): still warm, cloud increasing, possible light drizzle (Met Éireann)
• Night (10 PM – 6 AM Tuesday): clear and cool, low 7–12°C (RTÉ Weather)

Humidity is around 64% (Weather Underground), and barometric pressure is high at 30.39 inches – typical for a settled spring day.

Extended outlook (14 days)

After Monday’s heat, Tuesday brings mostly sunny but cooler conditions (high 21°C). Later in the week, showers return and the Bank Holiday weekend looks unsettled (Met Éireann). For a 14‑day picture, AccuWeather’s extended forecast shows a gradual cooling trend starting Wednesday (AccuWeather).

The catch: while Monday is ideal for outdoor activities, the narrow window means planning ahead is essential.

What is the climate in Ireland like?

Seasonal temperature ranges

Ireland has a temperate maritime climate (Köppen Cfb). Winters are mild (average 5–8°C) and summers cool (15–20°C). Tomorrow’s forecast of 27°C is about 7–10 degrees above the typical May average high of 16°C (Met Éireann). June, July and August are the warmest months, with averages of 18–20°C in Dublin.

Rainfall patterns by month

Rainfall is fairly evenly distributed, but December and January are wettest (about 70–80 mm per month), while April and May are driest (45–55 mm) (Met Éireann). Tomorrow’s 2% precipitation probability is extremely low for Ireland, even in spring.

Regional differences (east vs west)

The west coast (Galway, Kerry) receives significantly more rain due to Atlantic fronts, while the east (Dublin, Wicklow) is drier and sunnier. Dublin’s microclimate often means less cloud cover than the west (Met Éireann).

The trade‑off: visitors expecting typical “green Ireland” rain may be surprised by Monday’s heat, but the west will be cooler and cloudier.

When does it stop raining in Ireland?

Typical rainfall duration

Rain in Ireland can occur in any season, but it rarely pours for days on end. Most rain comes as showers or light spells. The notion of a “stop” date is misleading – May and June often have dry spells lasting a week or more (Met Éireann).

Seasonal drying trends

Spring (March–May) sees a steady decrease in rainfall. By May, Dublin averages about 55 mm of rain – the second‑driest month after April. Tomorrow’s near‑zero rain chance is at the low end of normal.

Impact on travel plans

For travellers, the key takeaway is that May and June are excellent months for reliability. However, always pack a waterproof layer – even on sunny days, an Atlantic front can bring a surprise shower (Met Éireann).

What this means: Irish weather’s volatility demands flexibility, even on days when forecasts are optimistic.

What is the best time to travel to Ireland?

Summer months (June–August)

Peak tourist season brings the warmest weather (average 18–20°C) and longest daylight (up to 17 hours). However, it also means crowded attractions and higher prices for accommodation.

Spring and autumn alternatives

May and September offer a sweet spot: warm enough for outdoor activities, fewer tourists, and lower costs. Monday’s 27°C is unseasonably warm, but a typical May day in Dublin is 16°C – still pleasant for walking tours (Met Éireann).

Winter travel considerations

December–February: short days (sunset around 4 PM), higher rainfall, but significantly cheaper flights and accommodation. Christmas markets add charm.

The pattern: May gives the best balance of weather, daylight and value. Tomorrow’s exceptional warmth is a bonus, not the norm.

For travellers arriving in Dublin this week, the choice is clear: enjoy Monday’s exceptional warmth with a walking tour or outdoor lunch, but keep a light jacket handy for the evening. Tuesday will still be pleasant, but the window for perfect sightseeing weather closes quickly as the week turns cooler.
