Met Éireann has warned that it could be an uncomfortable night’s sleep.

Beaches and waterways will be thronged today, so the national forecaster has also issued that usual water safety advice.

Met Éireann has also extended a nationwide weather advisory until Friday of next week, warning that the prolonged spell of hot weather is expected to last longer than initially forecast.

Daytime temperatures will “widely exceed 25 degrees”, with values climbing into the high 20s and possibly the low 30s in some areas by the middle of next week.

The advisory warns of potential impacts including heat stress, dehydration, uncomfortable sleeping conditions, wildfire risk and increased water safety concerns as more people head to beaches, lakes and rivers.

The forecaster is also warning that UV levels will be high to very high over the coming days, with the possibility of thundery showers developing later next week before temperatures return closer to average towards next weekend.

Ireland’s heatwave comes as much of Europe continues to endure extreme temperatures.

Spain, Portugal, Italy and Greece have all faced heat alerts in recent days, while authorities in southern Spain are battling a deadly wildfire in Andalusia that has claimed at least 12 lives.

Recurring heatwaves are becoming more frequent and intense as a result of global warming.
