There's no guarantee the sun will shine on this last weekend in August, but at least there's no shortage of music, culture and sport to keep everyone amused.
After a reportedly blistering set from Radiohead last night, Marlay Park in Dublin will again draw a crowd of thousands tonight for the Daft Punk gig, the latest in the Budrising Festival line-up.
This is the final Daft Punk gig out of eight in their summer world tour, and it's been 12 years since they last played in Dublin. Expect some traffic congestion around the venue this evening.
Dún Laoghaire promises to be one of the most lively venues this weekend as it plays host to its sixth Festival of World Cultures.
Over 150 artists and groups from over 50 countries will take part in the three-day intercultural celebration funded by Dún Laoghaire Rathdown County Council
There will be music, street theatre, dance, club nights, markets, exhibitions, workshops and activities for children throughout the weekend.
Letterkenny, Co Donegal, will also be buzzing this weekend due to the annual Fleadh Cheol na hEireann. It's the second year running that the event, billed as the world's largest celebration of Irish culture, has been held in the Donegal town.
There will be a number of traffic diversions and restrictions in place starting from 6pm tonight. Further information on the Garda traffic management plan is available at http://www.garda.ie.
More music and culture is on offer in Waterford, the venue for the 12th Dunmore East International Bluegrass Festival. Some 25,000 people are expected to attend the event, and some traffic congestion is expected.
For many, however, the most important event of the weekend is the Bank of Ireland Senior Football Championship semi-final battle between Dublin and Mayo.
The match kicks off at Croke Park at 4pm on Sunday and, as always, traffic will be busy around the Drumcondra and North Strand areas before and after the event.
The Garda says there will be two supervised car parks near the stadium, one at Clonliffe Road and one at O'Connell School, Richmond Street North (access off the North Circular Road).
Supporters are urged to arrive in good time to avoid congestion before the games start.
No traffic will be permitted to leave the car parks for approximately 45 minutes after the matches in order to allow pedestrians leave the area safely, the Garda press office said.
The Garda said supporters will not be allowed to carry air horns, flares, bottled alcohol or certain flag poles into Croke Park. They are also asked to have consideration for local residents and to refrain from anti-social behaviour.
Met Éireann says there should be some clear spells tonight with a few scattered showers. Tomorrow night will be mild, again with clear spells and isolated showers. Lowest temperatures will be between 10 and 13 degrees.
Sunday is also expected to be a mild, bright day but with some showers, a few heavy in northern areas.
