The Lowdown
Alright, let’s get into it. It’s Rusty here.
Right off the bat, I’ve gotta be straight with you – there’s no surf on the table for the next two weeks. The whole 16-day window is a flat spell. You’re looking at a full run of “poor surf conditions” from August 18th all the way through to September 2nd. That’s a long dry gap, and there’s nothing to get excited about.
The only spot we’ve got on the radar is Flagpoles, a beach and reef setup that’s super consistent but it’s barely showing a pulse. The best of the worst is on Thursday morning, August 27th, where we see a 1 ft swell from the ESE with a 12-second period. The combined energy is a weak 32 (moderate energy), but it’s still poor surf. The afternoon of the 27th has the same height and period, with a slightly higher energy reading of 58, but again, it’s not enough to recommend a paddle.
Water temp at Flagpoles is sitting at 87°F, which is about normal for this time of year with a 2°F anomaly – nothing wild.
The wind is a mixed bag. We get a few glassy slots – like Tuesday afternoon, August 18th, and Thursday morning, August 20th – but with next to no swell, those clean conditions are wasted. Most days are cross-on or cross-off, with winds anywhere from 3 mph to 12 mph, so the chop is usually a factor.
Look, if you’re desperate for a session, the early morning of Friday, August 28th, might be your best bet. It’s clean with a light cross-off breeze from the SW at 3 mph, and 1 ft from the ESE with an 11-second period. The energy is still weak at 33, but it’s the cleanest combo in the whole run. Honestly though, this is more of a longboard or even a swim-fin kind of day.
If you’re into kite surfing, the afternoons with stronger cross-onshore winds and a bit of wind chop might be more interesting than anything for a paddle board.
Hang in there. The forecast can always change, but for now, it’s a solid blank.
Rusty.

Information about the Flagpoles Surf forecast
The above surf forecast table for Flagpoles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flagpoles can be found by selecting the local surf guide option on the grey menu. Our Flagpoles 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 (Flagpoles) 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 Flagpoles 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.
Flagpoles is 3 km (2 miles) from West Palm Beach. If you plan a vacation in South Florida, look for hotels and other accommodation in West Palm Beach. West Palm Beach has rooms for a wide range of budgets as well as car hire and transport links.
