Ireland 'heatwave' hope as glorious weather maps show exact date temperatures to top 20C

Met Eireann has confirmed the weather news that Ireland has been hoping for, promising that conditions will soon take a turn for the better.

After seemingly months of unsettled weather, high pressure is forecast to return this week, which will favour clear skies and warm sunshine.

The national forecaster said: “High pressure is going to dominate the weather, bringing mostly dry conditions for much of the time, with a mix of cloud and sunshine and mostly light winds. It’s going to gradually become warmer too, with above average temperatures expected.”

The glorious weather U-turn is expected to begin from tomorrow, May 7, with 20C heat forecast. The warm spell will last for at least five days, with temperatures increasing through the week.

Thermometers could hit 21C towards the end of this week, which would make Ireland as hot as Istanbul. Even nighttime temperatures will remain balmy, occasionally not falling below 12C.

However, the welcome weather change is unlikely to be classified as an official heatwave. Heatwaves are often defined as five days of consecutive above average temperatures, but Met Eireann previously told the Irish Mirror: "That is a working definition used by some other met offices, but the Met Eireann definition of a heatwave is five consecutive days of temperatures above 25C.”

Giving a day-by-day breakdown of what to expect this week, the national forecaster said: “A mostly dry day Tuesday with good spells of sunshine. A few isolated showers are possible, mainly in the east. Highest temperatures of 15C to 20C generally, mildest in inland parts of Leinster, in light variable breezes. It'll be slightly cooler though in north Ulster and in some coastal parts. Dry and mostly clear to start Tuesday night before cloud builds from the west with the odd spot of light rain or drizzle possible near coasts by morning. Lowest temperatures of 5C to 10C, coolest over Ulster. Light southerly or variable breezes will allow some mist and fog to develop.
