Conditions at Lahinch in April
April: Spring Cleanup
April is a transitional month and often the turning point for more consistent offshore/clean conditions. The average swell height eases to around 4-5ft (1.4m) and the period settles at 10.8 seconds - enough for grinding runners but with less of that brutal winter weight. W and WNW swells are the most frequent directions, at 30.1% and 24.4% respectively, with WSW adding another 16.5%. It is a slightly more mixed bag: WNW and NW still wrap in, though the W/WSW energy remains the most reliable for wave quality. The big story is wind - 29% of readings are ideal now, the highest of the year so far, and the N/NE/E quadrant becomes increasingly involved as spring high pressure sets up off the Atlantic. Water temperature climbs to 9.9°C, rainfall drops to 2.8mm per day, and Lahinch often sees long sunny intervals between the showers. Best for fun, rippable surf rather than epic heavy days.
