It's Monday, July 13th, 2026, and if you're waking up in Ireland, you're likely already feeling the warmth. We're in the midst of what's shaping up to be a truly prolonged period of exceptional weather, and today is no different. Forget your usual grey skies and sudden downpours, because Met Éireann is predicting another cracker of a day across the island. The Ireland heatwave forecast tells us this warmth isn't going anywhere fast.

I think it's fair to say we've all been enjoying this spell. It's a rare treat to have such consistent, glorious sunshine stretching out for days on end. It changes the whole rhythm of life, doesn't it? Suddenly, evenings are for sitting out, lunches are al fresco, and the biggest decision of the day is whether to risk a swim in the sea or just stay by the lough. This isn't just a warm day, it's a full-blown Ireland heatwave forecast, and it's something we should appreciate while it lasts.

Today's Snapshot: Monday 13th July

Today is set to be another dry, very warm, and beautifully sunny day. No surprises there, given the pattern we've seen developing. Temperatures are expected to climb quite high, particularly in the south and west.

• Munster and Connacht: Expect the mercury to hit between 24 and 29 degrees Celsius. That's proper summer heat, folks.
• Leinster and Ulster: A little cooler, but still very pleasant, with temperatures ranging from 20 to 24 degrees Celsius.

A light to moderate east to northeast breeze will be present, which should offer a welcome relief in some areas, especially where the sun is really beating down. It's the kind of day that calls for light clothing, sun cream, and perhaps a good book in the shade. The Ireland heatwave forecast is certainly delivering on its promise of sunshine.

Tonight's Outlook

As the sun sets, the clear skies will largely remain. It'll be a dry night for most, allowing for some comfortable sleeping for many, though it will stay quite warm.

• Lowest Temperatures: We're looking at 13 to 18 degrees Celsius.
• Warmest Spots: The south of the country will hold onto the heat the most.
• Breezes: Light to moderate northeasterly breezes will continue through the night.

These are what we call "tropical nights" when the temperature doesn't drop below 20 degrees in some parts. While not quite tropical across the board, the south is getting pretty close. This extended period of warm nights is a key indicator of a significant Ireland heatwave forecast.

Looking Ahead: Tuesday 14th July

The good news is, the fantastic weather isn't going anywhere for Tuesday. Most areas will see another mostly dry day with widespread sunshine. There might be a slight change though, as some cloud could start to build over southern parts. There's also a chance of an isolated shower affecting the southwest later in the day. So, if you're in Kerry or West Cork, keep an eye on the sky, though it's likely to be a brief affair.

• Highest Temperatures: Generally between 23 and 29 degrees Celsius.
• Warmest Areas: The west will continue to be the hottest.
• Cooler Near the East Coast: The easterly breeze will keep things a little milder along the eastern seaboard.

Overall, Tuesday looks set to be another scorcher, reinforcing the persistent Ireland heatwave forecast.

The Week Ahead: A Prolonged Spell

Met Éireann's national outlook confirms what we've all been hoping for: this prolonged very warm or hot spell is set to continue for the week ahead. This isn't just a couple of nice days; we're talking about a significant period of warmth that will likely be remembered for years to come.

• Daytime Temperatures: Widely reaching the mid to high 20s.
• Nighttime Temperatures: Warm, with the possibility of tropical nights in some areas.

While it's largely expected to remain dry and sunny, there is a chance of showers and thunderstorms developing in certain parts. This is fairly common when you have such intense heat; the atmosphere can become unstable, leading to some dramatic, albeit often localised, downpours.

Let's break down the rest of the week briefly:

• Tuesday Night: Mostly dry with clear skies, though cloudier in the south and west with a chance of a few showers. Lowest temperatures of 14 to 19 degrees, warmest in the south.
• Wednesday: Another dry and sunny day for most. However, heavier showers or thunderstorms could develop, most likely affecting parts of the south, midlands, and west. Still very warm or hot, with temperatures generally between 23 and 28 degrees. The east coast might be a bit cooler due to the breeze.
• Thursday: Continuing very warm or hot. Dry and sunny conditions for most, but again, a chance of heavy showers and thunderstorms developing, primarily in the south and west. Highest temperatures generally between 24 and 28 degrees.
• Friday: Looks sunny and very warm or hot for many, with temperatures in the mid to high twenties. However, a northerly breeze might bring slightly cooler conditions to the north and northwest. Heavy showers or thundery downpours are still possible in parts.

This consistent Ireland heatwave forecast is certainly making for an eventful summer.

Staying Safe in the Sun

With such high temperatures and prolonged sunshine, it's really important to stay safe. Hydration is key, so make sure you're drinking plenty of water throughout the day. Sun cream is an absolute must, even if you think you don't burn easily. Head for the shade during the hottest parts of the day, typically between 11 AM and 3 PM. And please, never leave children or pets in parked cars, even for a short time. The temperatures inside can rise incredibly quickly and become dangerous.

This kind of weather is fantastic for getting out and enjoying all that Ireland has to offer, from our beautiful beaches to our stunning national parks. Just remember to do so responsibly.
