The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on offer for Bethany. I’ll be straight with you – this isn’t a week for setting the world on fire. It’s a real mixed bag of small, weak swell and tricky wind directions. We’ve got a run of poor surf right through the end of August and into the first week of September, so don’t be in a hurry to paddle out.
The first hint of anything rideable comes on Wednesday, 2nd September. The swell nudges up to 2ft from the ESE, with a period of 11 seconds giving it a bit of push. The combined energy is weak, sitting at 79, but the wind is offshore from the SW, so the morning will be clean. It’s not a standout, but it’s the best we’ve seen in a while. The water temperature is a touch warmer than normal for this time of year at 76°F.
Thursday, 3rd September, is a bit of a tease. The morning has onshore wind from the NE, so it’s messy, but the afternoon cleans up with a light offshore from the SSW. Swell is 2ft from the E, with a short period of 7 seconds, so it’s weak (energy 74). It’s surfable, but ordinary.
The real kicker, the only time I’d get excited, is the morning of Tuesday, 8th September. The swell jumps to 4ft from the SE, with a short period of 6 seconds. The combined energy is moderate (177). Now, the wind is cross-onshore from the ENE, which will chop it up, so it’s not the best quality. But this is the biggest swell of the whole forecast. The break is a beach/jetty setup, so with that short period and onshore wind, it’s going to be a bit of a mess. Honestly, for a surfer, it’s a struggle. If you’re into kiting, this setup looks more interesting than paddle surfing.
After that, the swell drops right back into the doldrums. From the 9th through to the 14th of September, we’re looking at ankle-biters of 0.7ft to 1ft, with a lot of cross-on and onshore wind. The energy is pitiful, often in the teens. There’s a glassy moment on the morning of Saturday, 12th September, but with only 1ft of swell, it’s a flat spell.
So, here’s the bottom line: the best of a poor bunch is the morning of Wednesday, 2nd September, for a clean, small wave. If you’re feeling brave, Tuesday, 8th September has the most size, but expect chop. Otherwise, save your energy.
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.
