The Lowdown
Alright, let’s talk about Lahaina Breakwall/Harbour on Maui. Looking at the whole 16 days, it’s a long, flat spell. The swell is tiny, the energy is weak, and there’s no real standout session anywhere. The first recommendation starts Monday, July 20th, and it’s just a bunch of small, ordinary days.
Monday morning, July 20th, some clouds, light northeast breeze offshore at 10 km/h. Swell is only 1 foot from the south with a very long 16-second period. That’s groundswell, good for shape, but the combined energy is only 105—weak. Water temp is 80°, pretty normal for this time of year. The waves are surfable but very ordinary. That afternoon stays clean with a gentle offshore breeze, swell bumps to 1 feet from the SSW, still 16-second period, energy at 125. Still tiny.
Tuesday, July 21st, same story: morning light offshore, 2 feet from the south, 14-second period, energy 140. Rain showers in the afternoon but wind stays offshore, energy drops a bit to 131. Clean but small.
Wednesday, July 22nd, swell shifts to the southwest and the period jumps to 24 seconds in the morning—very long period groundswell. But the height is only 1 feet, so it’s all period, no push. Energy at 165. Still not enough. The whole week goes on like this: 1 to 2 feet, offshore winds, but energy never gets above 217. The best day is probably Saturday, July 25th afternoon: 2 feet from the SSW, 18-second period, energy 214, with a gentle offshore breeze. That’s still just knee-high.
By the end of July and into early August, the swell drops even more. From July 30th onward, you’ve got days with energy under 100, and the wave comment says “poor surf conditions” or “surfable but very ordinary.” The last real surfable wave is August 4th morning, with 1 foot from the SW, 18-second period, energy 77—still weak.
So, no standout. No day to chase. The swell is too small, the energy is weak, and the consistency is just a long run of clean but forgettable waves. Crowds at Lahaina Breakwall can be around sometimes, but with this lack of swell, you’ll have it to yourself. If you’re really keen, maybe Saturday the 25th afternoon is your best bet, but keep expectations on the floor. After that, there’s a big gap of no real surf from July 30th through to August 4th.
