The Lowdown
Right, grab a coffee and settle in, ’cause I’ve had a proper look at Flagpoles for the next couple of weeks, and, well… it’s a bit of a flat one, to be honest. Flagpoles is a beach and reef setup, very consistent, but the swell just isn’t making much of an appearance. The water temp is right around 87°, which is about 2° warmer than usual for the time of year – nothing too wild, just a touch of summer holding on.
We’ve got a real dry spell to start. From Saturday the 15th right through until the middle of the week, the swell is tiny. Saturday morning you’re looking at a weak 3ft from the southeast, but it’s cross-on with a short, weak period of 5 seconds, and the combined energy is only 36 – that’s weak energy. It’s just messy and choppy. The whole first week is a write-off, with nothing but small, wind-affected dribble. There are days with glassy conditions on the Tuesday morning, but the swell is a flat 0.7ft, so it’s not even worth paddling out for.
The first real glimmer of hope comes later. We get a bit of a bump on Friday the 28th of August in the morning. The swell picks up to 3ft from the southeast, but the period is a disappointing 5 seconds. The combined energy is still only 69 (weak). The wind is a light cross-on, so it’ll be bumpy. It’s the best you’ll see in this window, but honestly, it’s still pretty average.
The standout in this entire 16-day outlook? There isn’t one. The only day that even gets close to being surfable is that morning of the 28th, but even then it’s a small, weak, short-period swell with onshore wind. It’s not going to hold any shape and will be a fight to get a ride. For a beginner-friendly spot, this is too small to even practice on.
For the rest of the time, the swell barely ticks over. There’s a long period of nothing, then later down the track a few days of even smaller waves with the odd risk of thunderstorms. If you’re a kite surfer, the stronger afternoon breezes on a few days might look more interesting than what I’m seeing for a paddle. Honestly, it’s a blank run for traditional surfing.

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.
