It can be very damp in September, October and November, however, and chilly too, with daytime highs averaging around 10-12°C.

Daytime temperatures are kept to a respectable 6 or 7°C thanks to the Gulf Stream. It's a popular time for walkers and ramblers and the snow on the mountains can be magical to behold.
Best Time to Visit the Ring of Kerry
The Ring of Kerry is a scenic route of just over 100 miles which takes in some of Ireland's most spectacular coastal scenery. In the summer months, you can expect the route to be very busy, with crowds at some of the more popular viewpoints and attractions. You can also expect glorious views, though, on sunny days.
If you visit the Ring of Kerry in the autumn or winter, you'll experience rain, and potentially lots of it. High winds can also lash the coastline, but this makes for some gorgeously evocative views with high waves and stormy skies. It's much less crowded at this time, which is a plus. Spring along the Ring of Kerry is very unpredictable, weather wise, but definitely worth doing if you want to avoid the crowds.
