Lahaina Breakwall/Harbour Surf Forecast and Surf Report

G’day, Rusty here. Let’s chat about Lahaina Breakwall/Harbour for the next couple of weeks.

Honestly, it’s a pretty quiet stretch ahead, with only a tiny bit of action right at the very end. Most of the first week and a half is knee-high and clean, but nothing to write home about. Water temp is about 81°, right where you’d expect for the season.

Starting Saturday the 15th of August, we’ve got a little 1ft SSW swell with a 13-second period, but a strong cross-off wind from the ENE at 25 mph makes it poor. Not worth suiting up.

Sunday the 16th: morning brings a 2ft S swell, 10-second period, lighter 6 mph ENE cross-off, energy up to 125 (moderate). Surfable but ordinary. Afternoon cleans up with a NE offshore at 6 mph and a 1ft SSW swell (13 sec, energy 124). Still small.

Monday the 17th through Wednesday the 19th are all tiny 1.0ft to 2ft swells from the SW or S, with gentle offshore breezes (NE/NNE). Energy stays weak to moderate (60–120). The Wednesday morning has a 1.0ft SW swell with a 16-second period – proper long-period groundswell, but barely any size. It’ll be consistent but small.

Thursday the 20th to Monday the 24th of August: same story. 1ft to 2ft SW swells, periods 14–18 seconds, light to gentle offshore or cross-off winds. Energy weak to moderate (74–147). The Friday morning (21st August) is the cleanest of this bunch – glassy with a 2ft SW swell, 17 seconds, energy 147. For this reef break, that long-period groundswell can wrap in nicely, but you’ll be scratching for waist-high waves.

Second week: Tuesday the 25th to Thursday the 27th of August, still 1ft SSW swells, 14–16 seconds, energy between 105 and 164. Offshore and cross-off winds, light to moderate. Ordinary.

Things pick up a touch at the end. Saturday the 29th of August: morning flat (1ft SSW, 9 sec, energy 57), afternoon sees a 2ft SW swell, 11 seconds, energy 109. Still nothing wild.

The best session is on Sunday the 30th of August. Morning shows a 2ft SW swell, 11 seconds, energy jumping to 168. The afternoon is the call: a 3ft WSW swell, 11 seconds, and the highest energy of the whole forecast at 211. Winds are light ENE cross-off, so it’ll be clean. That WSW direction is exactly what this break likes (optimum swell direction from the guidance is WSW). It’s only waist-high, but it’s the best pulse we’ve got. Crowds are only sometimes an issue here, so you might have it mostly to yourself.

This reef setup loves the long-period groundswell, but the size is just too small for most of the run. Flat spells happen here, so don’t be too bummed. Forecasts can shift.

If you’re into kiting, those moderate breezes and clean small waves might look more interesting than for a paddle surfer – especially around the 22nd to the 25th when winds pick up.

Stay patient. The last day has a little life. Keep watching.

Rusty.
