Bank holiday revellers face cold but dry weather as clouds roll in today.
The good news is that it will be possible to have a barbecue - as long as jackets are kept at the ready.
Met Eireann said the bank holiday will see a drop in temperatures as clouds cover the sun.
However, forecaster John Eagleton said that, other than a few showers, it will be a dry day.
"There's still going to be a lot of dry weather," he said.
"If we didn't have the sunshine it would be a bit chilly. The sunshine is masking the coldness of the air to some extent, and I think there will be an increase in cloud overall, particularly in the northern half of the country."
Temperatures will improve slightly into the beginning of the working week, but cloud will increase tomorrow and Wednesday.
"Through Tuesday and Wednesday there will still be a lot of dry weather," he said.
"The winds turn easterly, but the cloud will increase overall and it will stay cold. Temperatures will only be 9C to 12C or maybe 13C.
"We won't have as much sunshine and there will be rain in the south. There are bits and pieces of rain around for the week, but when you add it all up there's probably not a great deal."
The weather will continue to pick up at the end of the week, and current indica- tions suggest a gradual return to settled conditions and seasonal temperatures.
"Because it won't be sunny all the time you'll feel the coolness of the air. Up to next weekend, temperatures will only be 11C or 12C," said Mr Eagleton.
"If you get a bit of sunshine, it might get it up to 13C or 14C, but cloud will increase, so I'd say 11C or 12C many days will be the max."
