Met Eireann has forecast a sky-high 22C today but it's not all good news on the weather front.
The high temps will be surrounded by cloud, drizzle and patches of fog while remaining mild and humid for most of the day.
Overnight, there will be a band of patchy mist and drizzle across Dublin too.
Most areas will stay dry with clearer weather following towards dawn with temperatures sticking around 12C.
Majority of the week will be fresh, clear and dry with temperatures remaining in the high teens in an interesting turn of events for this time of year.
