The Lowdown
G’day, Rusty here. Well, I’ve gotta be straight with you—this stretch at Caspar Creek is looking pretty grim for the next two and a half weeks. We’ve got a long, frustrating gap of poor conditions ahead, so don’t get your hopes up for any kind of proper session. It’s a tough run for a spot that’s already pretty sheltered from the main swell.
Let’s start with the overall pattern. The next few days are just a write-off. From Sunday 6th September right through to Tuesday 8th September, the swell is small—waist-high at best—and the wind is all over the shop. Cross-onshore breezes, mostly from the NW, with a bit of chop and wind ripple. Wave energy is weak to moderate (141 to 186), and the period is short (5 to 8 seconds), so you’re looking at messy, weak lines. Not worth paddling out.
Come Wednesday 9th September, there’s a bit of a tease. The afternoon sees a sudden jump in swell period to 19 seconds from the SW, with energy way up to 586. That’s a long-period groundswell, but unfortunately the wind stays light cross-onshore from the WNW, and the height is only 3 ft. It’s still marked as poor surf conditions. A long-period groundswell that small at a sheltered spot like Caspar Creek just won’t deliver. You’d need a point break or reef to make anything of it.
Thursday 10th September is more of the same—a bit of SW groundswell energy in the afternoon (810) but again, cross-onshore wind and poor conditions. Friday 11th September is the biggest push we see: a solid 8 ft to 12 ft NW swell rolls in, with energy hitting 1536 to 2220. That’s strong energy, but the wind is a moderate to fresh cross-onshore at 15 to 19 mph, making it a choppy, lumpy mess. At 8 ft+, this is expert territory anyway, and with that onshore breeze, it’s not going to be clean. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
The weekend of 12th and 13th September stays big (7 ft to 10 ft) but the wind doesn’t let up. Cross-onshore NW winds, 9 to 19 mph, keep it poor. After that, the swell drops steadily through the second week. From Monday 14th to Saturday 19th September, we see heights between 2 ft and 5 ft, but the wind remains a persistent cross-onshore from the NW. A few days, like Tuesday 15th, have glassy conditions in the afternoon, but the swell is small (4 ft) and weak (141). That’s the closest we get to surfable—still only a score of 1 out of 10, described as “surfable waves but very ordinary conditions.”
The final days, 20th and 21st September, offer a tiny bump of SW groundswell (17 to 18 seconds) with energy up to 784, but again, only 3 ft to 3 ft and cross-onshore wind. It’s frustrating.
So, the standout? There isn’t one. The best on offer is probably Tuesday 8th September afternoon, when it’s glassy with a light 4 ft NW swell. That’s it. For a consistent beginner spot like Caspar Creek, this is an unusually blank run. It tends not to stay this poor for long, so keep an eye on the forecasts—they can change. But for now, I’d save the wax.
Rusty.

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