However, dreams of a long, hot summer may be premature.
Met Éireann predicts it will be mostly dry this weekend, although temperatures will dip slightly tomorrow before becoming noticeably cooler on Monday.
Although not as warm as yesterday, many areas will enjoy highs of up to 20C today, dropping to 2C-8C tonight with some patches of mist and fog.
Today will start with a mix of cloudy and sunny spells, clearing to periods of mild sunshine. It will be mostly dry again with a mixture of sunshine and cloud. It will feel fresher fresher than yesterday, with highest temperatures ranging from 13C or 14C on east and north coasts to 18C inland, but still up to 19C or 20C locally in the South-west. Winds will be mainly light and variable.
After a cool start tomorrow, the pleasant weather is expected to continue, although there is a prospect of isolated showers in the southwest of the country. However, those areas are expected to enjoy a silver lining by way of the highest temperatures nationwide.
It will be cooler along the north and east coasts with onshore breezes and affternoon temperatures will range from 12C to 14C.
It will be milder elsewhere, with plenty of sunshine and with highs of 15C to 18C or even 19C.
Monday will be milder than tomorrow, with temperatures ranging from 16C to 20C in the Midlands and along southern coasts while northern coasts will be much cooler. Dry with good spells of sunshine, though cloud will probably build in the evening, bringing some rain after dark.
After a pleasant weekend, it looks like rain will return on Tuesday which will see a damp start to the day with scattered outbreaks of rain and drizzle as well as mist and low cloud.
Brighter, fresher weather is expected to develop in the afternoon, but a few well scattered showers will also develop. Temperatures will drop along Atlantic coasts but it will still feel reasonably mild across the Midlands, South, and East. Highest temperatures will range 12C to 17C.
Looking further ahead, there is little prospect of a long, warm summer, according to AccuWeather, an American company that provides commercial weather forecasting services worldwide.
Its long-range forecast for Ireland and UK suggests that outbreaks of rain will prevent temperatures from rising over the summer, but southern Europe will be sweating this summer as long stretches of above-normal temperatures and dry weather dominate.
High pressure sitting to the west of Ireland will keep temperatures at bay both here and in Britain.
While the centre of the depressions will often pass near or north of Scotland, rain will frequent much of Ireland and the UK, with the heaviest falls expected in the North, western Scotland, and northwest England.
