The Weather in Dublin, Ireland in April

Updated: 8 febrero 2023

April marks the beginning of the tourist season in Dublin, although it still tends to be cold so crowds are not as large as during the summer. 


Daytime high temperatures early in April tend to average near 11 C (51-52 F)) warming to near 13 C (55-56 G) by the 30th. 

A few of the warmer afternoons, especially later in the month, can warm up to near 16 C (about 61 F).

The record high temperature in Dublin during April is 20.5 C (68.9 F).

Late night and early morning low temperatures average around 4 C (39 F) early in April, warming to about 6 C (43 F) near the month’s end. 

A few of the colder mornings, especially early in the month can dip down to around 1 C (about 34 F).

You should expect only about 2 days this month reaching 0 C (32 F).  The record low temperature in Dublin during April is -4 C (24.8 F).

Clouds and Precipitation

About 13 days this month will be sunny, or at least partly sunny. 

About 15 days record some rainfall, however, only 3 days, on average, will total 5 mm (0.2 inches) or more of rain. 

Snow occurs, on average only on 1 day but rarely accumulates.  


Daylight hours increase rapidly throughout this month from just over 13 hours on the 1st to 15 hours by the 30th.

This should allow ample time to explore this city.
