The Lowdown
Alright, Rusty here. Let’s call it as it is. Honestly, the next 16 days are a tough stretch. We’ve got JT Flemming as the only spot on the cards, and it’s a point break that rarely breaks, so this is a real patience tester from the start.
We kick off on Wednesday, August 12th, but there’s nothing to get excited about. That swell is coming from ENE at 6 ft, but it’s short period at 6 seconds, so it’s weak and messy. With a fresh 30 km/h cross-shore wind whipping across, it’s lumpy cross-chop and just poor conditions. The combined swell energy is low, sitting at 196 – you’d be battling a washing machine for no reward.
That same story holds right through the first week: Thursday and Friday see the swell hanging around 5 ft to 7 ft, but it’s all the same story – short period junk from the ENE and cross-shore winds in the 30 to 35 km/h range. The water temperature is 27°, which is pretty much bang on average for the time of year, so no surprises there.
By Saturday the 15th, things get a bit more serious in terms of size – we’re looking at 8 ft swell with a period stretching to 8 seconds, and the combined energy jumps into the strong range at 924 and 1006. Problem is, the wind is howling at 45 km/h and it’s still cross-shore, whipping up messy cross-chop. That size is expert-only territory at the best of times, but with those winds, it’s a complete write-off for surfing – honestly, that setup looks more interesting for kite surfing than paddle surfing.
Sunday the 16th offers a brief glimmer: the wind swings to cross-offshore from the E, dropping to 30 km/h by the afternoon. The swell is still 7 ft in the morning and 6 ft in the afternoon, period around 8 seconds, so the waves start looking cleaner. But it’s still not a standout – the crowd can be an issue at times here, and the waves are inconsistent because the break rarely breaks. Still, if you’re an expert and you time it right, Sunday afternoon might give you a few clean ones.
After that, it’s a long, slow fade. From Monday the 17th through to the end of August, the swell drops steadily: 5 ft, then 4 ft, then down to 3 ft and even 0.7 ft by the 23rd. The period stays short, wind stays cross-shore, and the combined energy falls to weak levels – mostly two-digit numbers in the 60s and 80s, with a few weak three digits around 100. It’s basically flat and blown out for days on end.
There is a brief uptick on Monday the 24th and Tuesday the 25th, but it’s only 3 ft to 4 ft of short-period ENE windswell, and the wind never goes offshore. The last few days of the month wobble around 3 ft to 3 ft, but again, always cross-shore, always poor.
Let’s be real: there’s no standout here. The best of a bad bunch is Sunday the 16th, especially the afternoon, when the cross-offshore wind cleans things up on the 6 ft ENE swell. It’s not great, but if you need a paddle, that’s your window. After that, the forecast suggests a blank run that’s pretty normal for this area – when JT Flemming rarely breaks, you get long gaps like this.
Keep an eye on the charts, but for now, leave the board in the car.

Information about the JT Flemming Surf forecast
The above surf forecast table for JT Flemming provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at JT Flemming can be found by selecting the local surf guide option on the grey menu. Our JT Flemming surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (JT Flemming) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for JT Flemming may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
JT Flemming is 21 km (13 miles) from Wailuku. If you plan a vacation in Maui, look for hotels and other accommodation in Wailuku. Wailuku has rooms for a wide range of budgets as well as car hire and transport links.
