SPRING – March, April, May
Dublin has a temperate, maritime climate that doesn’t see a lot of rapid change in weather throughout the year. March will still bring drizzly rain showers, so don’t forget your rain jacket
if visiting during this time. You’ll see temperatures rise in April and May, so you’ll want to pack a lighter cardigan
, and maybe even some sandals
You’ll see average temperatures approaching 50 degrees Fahrenheit in March, but progressing to the 60s by May.
SUMMER – June, July, August
Summer in Dublin is pleasantly warm and not extreme in anyway. You’ll typically find the warmest and driest days during these months, though you may still see an occasional drizzly day. Pack your sunglasses, T-shirts, and a sweater for the evening. This is also the most comfortable time of the year to be wearing a “going out” dress in the evenings.
You’ll pretty much see temperatures hover around the mid 60s to mid 70s degrees Fahrenheit throughout the summer months. Nighttime temps can drop to the low 50s.
FALL – September, October, November
September is still quite warm, but as October and November come, you’ll see more cloudy skies and lower temperatures. You might want your wool socks
and warm hat
by the time October hits, but I’d still have a T-shirt and light sweater for the days that tend to be a little warmer.
September will still have days that reach the low 60s, but by the time November is here, you can expect highs of 50 degrees Fahrenheit with lows of 40 degrees.
WINTER – December, January, February
Though Dublin’s winters are nowhere near as extreme as some other areas of the world, it still has its fair share of cold and rainy weather. Snow is pretty unlikely in the city, so you’ll primarily be battling rain and wind with an occasional crisp, sunny day. Pack the flannels, insulated vests or winter coats, and any other warm base layers you might want.
Average temperatures throughout the winter months tend to be in the low to mid-40s.
