The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Octagon House is a real quiet one. The data’s showing us a long stretch of small, weak surf and mostly onshore winds, so we’re not looking at any real standout sessions. It’s a poor run of conditions, and if you’re chasing waves, you might be waiting a while.

The water temp is sitting at 87°F, which is a touch warmer than normal for September. That’s the only warm note.

We kick things off from September 13th right through to the end of the month, and it’s all "poor surf conditions" according to the numbers. The swell barely gets above 3ft for the first week-and-a-half, with period hanging around a short 5 to 7 seconds. That’s windswell, not groundswell. You’ve got cross-onshore and onshore wind from the SSE and SE, chopping everything up. The combined energy is in the weak range, mostly between 13 and 32 – nothing doing there.

Then on September 17th, we see a pulse of swell side from the ESE picking up to 4ft to 5ft, with the period stretching to 6 seconds. Energy climbs to 115 and even 156 – moderate range now – but the wind is a cross-onshore E at 16 mph. It’s going to be lumpy and messy. Octagon House is an exposed spot taking swell from the SE, which is close enough to that ESE direction, but the wind just kills any chance of a clean wave. That day, the bigger surf makes it better suited to kites than paddling.

September 19th brings a moment of calm – glassy conditions in the morning with a light NW breeze, but the swell has dropped back to 2ft with weak energy (40). The 20th sees some offshore wind from the WNW in the morning, but the swell is a tiny 1ft. That’s barely a ripple.

From September 22nd through to the 28th, we’re stuck in a pattern of small swell (1ft to 4ft) and cross to cross-onshore winds from NE and ENE. The energy stays weak to moderate, maxing out at 102 on September 25th afternoon with a 4ft ESE swell at 6 seconds. The period is short, the wind is onshore, and the wave comment for this entire period is "poor surf conditions." Even September 19th and 21st mornings, with glassy conditions, have no swell to ride.

So, the honest truth: there’s no true standout in this window. It’s a long dry spell. Octagon House isn’t delivering. If the wind goes offshore on a bigger swell day (like the 17th or 25th of September), that might be your best gamble, but it’s a long shot. As it stands, this setup looks more interesting for kite surfing than paddle surfing. Keep your eyes on the forecasts, it tends not to stay this flat forever.

Rusty.

Information about the Octagon House Surf forecast

The above surf forecast table for Octagon House provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Octagon House can be found by selecting the local surf guide option on the grey menu. Our Octagon House 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 (Octagon House) 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 Octagon House 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.
