When to Go
The best times to visit the Ring of Kerry, Killarney, and Dingle are mid-March to June, and September and October. In July and August it's the peak holiday period, meaning roads are more crowded, prices are higher, and the best places are booked in advance. March can be chilly, with daily temperatures in the 40s and 50s. The average high in June is 65°F (18°C), which is about as hot as it gets. May and June are the sunniest months, while May and September are the driest months. The farther west you go, the more likely you'll get rain. The weather is not such a crucial factor in Adare and the Limerick area, but from November to mid-March daylight hours are short, the weather is damp, and many smaller places on the Kerry coast and in Killarney are closed.
