What the numbers don't tell you
July is peak season, with school holidays, Longitude in Marlay Park in the first weekend and the heaviest US arrivals. Afternoons average 19 °C, rarely hot, with rain on about thirteen days. Expect queues at the Guinness Storehouse and the Book of Kells, and book both ahead. Rates are the highest of the year. The GAA football and hurling quarter-finals begin filling Croke Park at weekends.
The Galway Races in late July draw Dubliners west for a week. Daylight lasts until after half past nine. The Dublin Horse Show at the RDS follows in August. The coastal walks and the Dublin Mountains are at their best. For the August bank holiday and the Horse Show, see August; July and August are equally busy.
