Met Éireann is forecasting mixed weather for the rest of the week, as the meteorological summer officially begins tomorrow.
The west and southwest of the country can expect some cloud and drizzle tomorrow, thanks to rain which is moving up from the Bay of Biscay.
Away from these coastal areas, the weather is still expected to be fine with temperatures reaching the high teens or low 20s.
Met Éireann said the temperatures being recorded at the moment are slightly above average for this time of year.
But as rain moves in from Wednesday, temperatures in the south and west are likely to be below average for June, said the forecaster.
After a mixed week, the June bank holiday weekend is going to see the re-establishment of dry weather and decent temperatures.
"It won’t be quite as warm as the weekend just gone," said Met Éireann, but temperatures above 20C will be "possible".
