The Lowdown
Alright, let’s look at what we’ve got for Flagpoles.
It’s a dead quiet stretch over the next 16 days. From Friday August 21st through the end of the month, the surf is basically non-existent. Swell stays tiny — never more than about 0.6ft and mostly under 0.6ft — and the combined wave energy is weak, with numbers ranging from 4 to 42. That’s pretty much flat. There is a brief glassy calm on Sunday morning the 23rd, but even then you’re looking at ankle-high 0.6ft waves from the ENE with an 8-second period.
Through early September, nothing changes. We’re still looking at 0.6ft to 1ft slop at best from the east and southeast, with poor surf conditions and a lot of onshore or cross-onshore wind. Periods are mostly short — 3 to 4 seconds on the 5th — though you get a random 15-second pulse on the afternoon of August 27th, but with only 0.3ft of swell, it’s just a shimmer on the surface.
Water temp is 87°F, typical for this time of year. No real standout here. Even for beginners, it’s mostly just a paddle in flat water. The second week is quieter and even more inconsistent. Crowds won’t be a problem because there’s nothing to ride.
I’d leave the board at home. This is a proper flat spell for Flagpoles.

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.
