Despite the return to a more traditional Irish summer, the roads will still be busy this weekend with a variety of sporting and cultural events taking place around the country.
Met Éireann is forecasting intermittent rain and drizzle with highest temperatures of 16 to 20 degrees over the weekend.
The annual Puck Fair is currently in full swing in Killorglin, Co Kerry, with a traditional cattle fair taking place today.
The fair finishes tomorrow on Scattering Day, when the reign of the festival's goat-king comes to an end, and it is expected that 100,000 people will have visited the small Kerry town over the festival.
The Kilkenny Arts Festival kicks off in the Marble City this evening and organisers expect 80,000 people to attend events there over the next 10 days.
Traffic in Kikenny will be disrupted tomorrow to facilitate The Big River Parade, a co-production between Macnas and Kilkenny Collective for Arts Talent that starts at 4pm.
Audiences may be down somewhat in Kilkenny on Sunday afternoon as the county faces off against Clare in the All-Ireland hurling semi-final at Dublin's Croke Park.
That game will be a double-header, with the football quarter final between Laois and Mayo the curtain-raiser at 2pm. Although it is unlikely that the stadium will hit its 80,000 capacity, tomorrow afternoon's football match between Dublin and Westmeath at the venue is sold out.
The Dublin Horse Show also continues at the RDS until Sunday evening and is expected to attract large crowds. As a result those attending are asked to use public transport if possible, although there is limited parking at the Merrion Cricket Club on Anglesea Road and Wanderers Rugby Club from which a park-and-ride facility will operate.
Large crowds are also expected in the Phoenix Park for the annual Phoenix Park Motor Races which take place tomorrow and Sunday. There will be road closures in the park and other traffic restrictions in the Park on both days.
In Cork the southbound lanes of the Jack Lynch Tunnel are closed until 11am on Monday morning, and a contraflow system is in place on the northbound lanes. AA Roadwatch advises that delays of up to 20 minutes at peak times are likely as a result.
Following yesterday's security alerts in London, flight departures at Irish airports are back to normal, but those collecting passengers today should note that flights from the United States and Britain are over an hour late arriving into Dublin and Shannon.
