The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, I’m looking at a pretty bleak stretch ahead. For the first week and a half, there’s nothing worth paddling out for. The surf is just poor, day after day. From Monday the 20th of July right through to the end of the month, the conditions are a write-off. We’ve got a moderate to fresh cross-shore breeze blowing from the ENE at 9 to 25 mph, and the swell is a messy, short-period affair with periods mostly between 5 and 8 seconds. The wave energy is weak to moderate, with the combined energy reading between 83 and 452. It’s basically a lot of lumpy, cross-chop with no shape or power. Don’t even think about it.
The first real glimmer of something comes on Wednesday the 29th of July. Even then, it’s only marginal. The swell pushes up to 6ft to 6ft from the NE with a period of 11 seconds, which brings a solid groundswell feel. The combined energy jumps right up to 759 to 845, so there’s proper power in the water. This is a proper point break, JT Flemming, and it’s rarely breaks, so when it does, it’s a special thing. The wind is a gentle cross-shore from the ENE, keeping things a bit lumpy but rideable. The water temperature is about average for the time of year. This is the only time in the forecast that offers any real chance of a wave, but the quality is still only marginal.
After that, it drops right back off. From Thursday the 30th of July onwards, we’re back to poor surf with weak, short-period junk and moderate cross-shore winds. The swell fades to 2ft to 3ft by the first week of August, with the energy dropping to between 28 and 162. It’s just a flat, blown-out nothing.
So, if you’re desperate, the 29th of July is your only shot. But don’t get your hopes up. The rest of the 16-day window is a total bust.

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.
