It's back to brollies for the rest of the bank holiday weekend as the sizzling temperatures of recent days become a distant memory.
While the weekend got off to a dry start, wet weather is expected this evening with a few showers in southern areas. Eeasterly winds will persist overnight.
By tomorrow the Mediterranean conditions of recent days will have disappeared, with lower temperatures and fresh winds making it feel even cooler.
Some prolonged heavy showers are expected in Munster and Leinster by afternoon, although further north will remain relatively dry.
On bank holiday Monday, the rain will fall in earnest right across the country and the temperatures will drop towards the low teens.
Weather experts say the day will be wet and windy with widespread showers or longer outbreaks of rain.
A stiff easterly breeze will bring the temperatures down to between 12C and 16C.
The cooler conditions will improve later in the week but it will still remain "rather unsettled", forecasters said.
Tuesday will start off cloudy and damp, but as the day goes on showers will be confined to the south and southwest with fresh easterly breezes all over.
Wednesday will see the winds easing somewhat, but there will still be a few outbreaks of rain with the west and southwest most at risk.
