The Lowdown
Alright, Rusty here, let's talk surf. We've got a bit of a slow burn on our hands with Flagpoles. The water’s sitting at a warm 87.1°, which is a touch warmer than normal for this time of year.
Right now, we’re looking at a big ol' stretch of nothing. From Sunday the 13th right through to Tuesday the 22nd of September, we’ve got tiny, weak surf with messy winds. It’s all under 1.5 ft for most of that first week, with the odd leg-stretcher only just cracking 3.3 ft on the 22nd but still with poor conditions. That’s a solid 10-day gap of just poor surf and not worth paddling out for.
It’s not until Wednesday the 23rd of September that things finally start to look interesting. We get a pulse of 5.2 ft swell out of the NE, and while the period is a middling 10 seconds, the real winner here is the wind.
The standout window is Wednesday the 23rd through Friday the 25th. That’s your target. Wednesday morning we get a clean 5.2 ft swell with light SW winds offering a cross-offshore flow. By Wednesday afternoon, the wind swings to a moderate W offshore, keeping it clean. Thursday the 24th keeps that quality going with 4.9 ft to 5.9 ft waves and light offshore or cross-offshore winds. Friday the 25th is the peak for size with a 6.2 ft swell out of the NE, and with very light WSW winds, it should be super clean.
The swell direction (NE) is right on the money for Flagpoles. That's the best run of the entire forecast, offering clean, fun, shoulder-high waves at a spot that is very consistent. Definitely the time to clear the schedule. After that, it starts to drop off again into messier conditions by the 27th, so don't sleep on that mid-week window.

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.
