The good news is that it is going to be dry and settled for the most part this week.
The bad news is that the weather should be even better and temperatures will get no higher than 21 degrees.
The reason for these relatively cool temperatures is a mystery to Met Éireann as conditions exist for highs of around 25 degrees this week, according to forecaster John Eagleton.
"There's no answer to that. I can't think of any reason why it is not as warm. Even in Spain it is cooler than it should be. There may be a weak front which complicates things," he explained.
The highest temperatures will be on Tuesday and Wednesday which will see highs of 21 degrees.
Met Éireann is forecasting the east and southeast will have the best of the temperatures this week, but Atlantic coastal areas will remain dull and misty with patches of drizzle and fog. Any rain that falls will fall in western areas.
Wednesday will be mainly dry with some bright or sunny spells. A few spots of light rain or drizzle will occur. It will be warm and humid in the south and east, with maximum temperatures of 17 to 21 degrees.
Thursday will have a similar east-west split with highs of 22 degrees in the east and south but only 18 degrees in the west and north.
The outlook for the weekend is uncertain, but early indications suggest that there will still be a good deal of dry weather, although a few showers or spots of rain are possible and it may turn a little cooler and fresher over the weekend.
“There seems to be more showers around for next weekend but not in any dramatic way,” Mr Eagleton stated. “ Temperatures will go back to mid-teens. It’s good weather for getting out and about, but people will still need to wear a jacket.”
