Weather in April
In Arklow, April marks the transition from spring's cool beginnings to warmer temperatures. The longer hours of daylight reaching 14 hours and the noticeable hike in sea temperature from 8.5°C (47.3°F) in March to 9.3°C (48.7°F) all add to this change. The city witnesses a brightening landscape as green returns to the trees and flowers begin to bloom. April is a relatively dry month, characterized by clearer skies and the beginning of more temperate weather.
Note: Swimming in 9.3°C (48.7°F) can be lethal. Merely spending a few minutes in 13°C (55.4°F) waters feels harsh, and venturing below 10°C (50°F) might disrupt breathing control and bring about cold shock, contingent on individual resilience.
On the first day of April, sunrise is at 6:56 am and sunset at 7:59 pm. On the last day of the month, sunrise is at 5:52 am and sunset at 8:50 pm IST.
