The Lowdown
Right, Bethany, it's a bit of a flat spell for us here, I won't lie. The whole 16-day window looks pretty grim, with no real standout sessions to get excited about. The swell just isn't showing up, and when it does, it's tiny and weak. We're looking at a long stretch of small, weak waves—mostly around 0.7ft to 2ft—with poor conditions. The water is a balmy 77°, which is much warmer than normal for this time of year, so at least it's nice for a swim.
Starting off Tuesday, September 8th, we've got a tiny 1.0ft swell from the ENE with a period of 9 seconds, but it's cross-offshore winds, and the surf is just poor. That's the story right through the rest of the week. There's a glimmer on Thursday afternoon, September 10th, with glassy conditions on a 0.7ft ESE swell, but it's still just too small to ride. The combined wave energy is barely a whisper at 9, so it's a dud.
The weekend doesn't bring any relief. Saturday, September 12th, has a 1.0ft SE swell with cross-shore winds and a chop. Sunday morning, September 13th, shows a slight bump to 3ft from the SE, with a combined energy of 161 (moderate), and cross-offshore breezes. The notes say "surfable waves but very ordinary conditions," which is about as optimistic as it gets. That's the best we've got, and it's still not great.
After that, it's back to the same pattern. The following week is a mix of tiny swells, onshore winds, and poor surf. There's a chance on Monday, September 21st, with a 2ft SSE swell and moderate offshore winds, but it's still just a knee-high dribble.
Look, this is one of those periods where the ocean just isn't cooperating. It's a blank run, and for a spot like this, it's not unusual to see a long stretch of nothing. Keep your eyes on the charts, but for now, the board stays in the shed. Rusty.

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