Conditions at Imsouane in May
May: Smaller, Cleaner, Summertime Vibe
May settles into a classic late-spring rhythm. Average wave height falls to 1.9m (6ft) and the period drops further to 9.3s, meaning the swell is no longer true long-period groundswell but a mix of groundswell and windswell. The rose becomes remarkably one-dimensional: a huge 62.6% of wave energy arrives from the NNW, with NW contributing 15.9% and WNW 3.9%. That is great for anchoring the bay's longboard-friendly consistency, but the wave quality is more 'fun and rippable' than 'deep and powerful.' Winds remain favourable for 53% of the time, with the NNW flow at 43.5% acting like a natural offshore breeze and keeping the surface clean. Daily precipitation is becoming scarce at 0.33mm, air temps average 19.6C, and the water has warmed to 17.6C. Conditions are small-ish and groveling, but on the best day you can still find a beautiful lined-up wave wrapping around the bay.
