Sun-worshippers made the most of yesterday's great weather as temperatures soared to 21 degrees.
Dubliners were in a joyous mood as they enjoyed the sizzling heat - but forecasters have warned the weather won't last for the rest of the week, with clouds set to dominate in the coming days.
The fleeting hot weather also had its negative effects, with the Dublin Fire Brigade sending four units to fight a gorse fire near Hollywood Lakes Golf Club in Howth yesterday afternoon.
"We had three pumps, a water tanker and a district officer there. There were no injuries, but we had to evacuate a nearby car park," a spokesperson told the Herald.
This came days after a similar gorse fire had broken out on Ireland's Eye, where several units of the fire service and the Air Corps fought the blaze for a number of days.
Met Eireann has predicted that conditions for the rest of the week will be warm, but cloudy.
"It'll stay fairly warm, but a lot cloudier with less evident sunshine today, while Thursday will see bits of rain here and there throughout the day," said forecaster David Rogers.
"It'll clear away on Friday morning and then we'll have a mix of sunshine and showers for most of the day."
The weather doesn't bode well for sports fans this weekend, with blustery, wet conditions expected on both Saturday and Sunday.
So Hill 16 supporters are best advised to bring rain gear to Croke Park on Sunday, when Dublin take on Kildare in the Leinster SFC semi-final.
