Conditions at Bundoran in April
April: Spring Transition
April marks the first noticeable step down in energy. The average wave height falls to 3-4ft (1.1m) and periods settle around 10.7s - still a solid long-period signal, but with less size and power than the winter months. The swell remains very directional from W-WNW-NW, with WNW still accounting for 30 percent of observations, though the most common wave heights shift down into the 0.5-1m and 1-1.5m classes. That means clean, user-friendly waves rather than heavy winter slabs.
Interestingly, April posts the highest ideal wind percentage of the year at 32 percent. With more frequent high pressure over the continent, easterly/southeasterly offshore flow becomes more common, and this can put Bundoran in a golden scenario: chest-to-head-high, long-period swell with smooth offshore texture. Air temperatures climb to about 7.6°C and water to 9.7°C, making the sessions noticeably more pleasant while still requiring a good wetsuit.
