Who needs Lanzarote when there's not a cloud in the sky over Ireland? Met Éireann's forecast on the tropical heatwave

Forecaster has a heat warning


Quiet airport in Lanzarote with no clouds over Ireland

There wasn't a cloud in the sky in the Met Éireann published satellite image of Ireland published this weekend with the tropical air set to scorch the country for a few days to come.

However, with lots of sun and high temperatures the forecaster warns has a health warning about getting too much of the hot weather.

In a commentary on the conditions Met Éireann meteorologist, Aoife Kealy said a high pressure continues to build over Ireland from the west on Thursday and Friday.

"The system brings with it a tropical maritime airmass, which will give us settled, largely dry and warm weather for the end of this week and through the weekend," she said.

She said daytime temperatures reached the low to mid-twenties towards the end of the week.

"Over the weekend temperatures will be higher still, widely reaching the mid to high twenties.   Alongside these very warm days, the coming nights will be warm and humid, with overnight temperatures often in the mid to high teens.”

Aoife continued: “It’ll certainly feel summery over the next few days as temperatures begin to rise and sunshine becomes more widespread". MORE BELOW SATELLITE IMAGE TAKEN ON Saturday morning.

However, the weather expert had a word of warning.

"Most places will find themselves under long spells of sunshine. So if you are out and about enjoying the nice weather, make sure to follow HSE advice and be sun smart as the UV index will be high or very high in the coming days,” she said. So how long will the warm and sunny weather last? MORE BELOW IMAGE

The commentary says current indications suggest that this warm and settled spell will last for much of next week as high pressure remains the dominant driver of our weather. Aoife says it will remain largely dry, though there is the chance of occasional showers. Staying warm also; daytime temperatures will reach the mid-twenties in many areas, possibly higher locally, and the nights will continue warm and muggy.

The overall outlook on the Met Éireann official forecast is for the high pressure bringing predominantly dry, very warm and mostly sunny weather for much of next week. Remaining very warm and humid at night also. However, there are signs that next weekend could bring a different set of conditions. MORE BELOW TWEET.
