Late night and early morning low temperatures will tend to be near 12-13 C (54-55 F) early in the month, cooling to near 11C (52 F) by the end of the month. 

A few of the cooler mornings, especially near the end of the month, can dip down to around 8-9 C (about 47 F).  The record low temperature in Dublin during August is 2.4C (36.3 F).

Ocean Temperatures

Dublin lies along the western edge of the Irish Sea which during August is still quite chilly with temperatures averaging near 14-15 C (58-59 F).


What to wear in Dublin during August?

August is the end of Summer so dress in layers as late night and early morning temperatures can be chilly, especially towards the end of the month. Afternoons, however, still tend to be mild to warm.

Also bring both short and long-sleeved shirts, warm socks and water-resistant walking shoes or boots.  In addition, jeans, or other travel pants along with a light-weight jacket and a sweater or two are suggested.


Things to Do in Dublin in August

Since there will likely be plenty of sunny days to enjoy in Dublin this month, it's an excellent time of year to take a pay-what-you-wish walking tour.

This will also be a good time to attend a sporting event, as the Bohemian FC will be playing at least a few home games this month. There are usually at least a few decent concerts to see during the summer as well.

If it's particularly warm, you might want to consider taking a boat tour or a cruise.
