The Lowdown

Alright, I’m gonna level with you: it’s flat. Real flat. From now through the whole 16-day window, there isn’t a single session worth paddling out for at Octagon House (this side of the lake). Every single line in the book is labelled “poor surf conditions” with a score that tells me there’s nothing to get excited about. The biggest swell we see barely nudges 3 ft, and the period sits at a weak 4 to 8 seconds – that’s windswell junk with no grunt. Combined wave energy never cracks 54 (weak), so you’re looking at dribble at best.

Starting Saturday morning August 22, we’ve got a 1 ft SSW swell with a cross-off breeze – looks clean but there’s no power. By afternoon it’s onshore and choppy. That same story repeats day after day: a little bump here and there, 1 ft to 2 ft, mostly from the S or SE, and winds that are cross-on or onshore. We get a couple glassy moments – like Friday August 28 morning (2 ft, glass) and Saturday August 29 morning (1 ft, flat calm) – but even then there’s zero push. The period is too short, the heights are knee-high at best, and the combined energy sits between 5 and 26 (weak). This isn’t surf, it’s a lake ripple.

By early September, the swell drops even further – 0.7 ft to 0.3 ft with longer period (6 to 8 seconds) but that’s just a longer wait for nothing. Thursday September 3 morning shows a clean 0.3 ft SE swell with a cross-off breeze, but come on – that’s a puddle.

There’s one brief moment that might interest a kite surfer: any afternoon with a solid 12 mph cross-on or onshore wind and that small bump – like Sunday August 30 afternoon (2 ft SE, 12 mph onshore) – but for a paddle surfer, it’s a hard no.

Water temp is about average for this time of year – nothing weird there. But the truth is, for this spot on the lake, a blank run like this isn’t unusual. It’s a pretty consistent setup for flat spells. Forecasts can change, but right now there’s nothing on the table. I’d save the wax for another week and keep an eye on the sky.

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.
