The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Caspar Creek. We’ve got a long stretch ahead, and I’ll be honest with you – it’s not looking like a classic run for paddling out. The whole 16-day window is a bit of a struggle, with the wind being the main culprit.
We start off on Sunday the 23rd with some swell, but it’s the cross-onshore wind that’s the problem. We’ve got a 5ft to 6ft NW swell rolling in, but that NW wind is blowing straight across it, making it choppy. The combined energy is moderate (508), but the quality is just poor. It’s a tough start, and the wind doesn’t let up through the week.
Monday the 24th sees a drop in size, with a 2ft SW swell, but the wind is still on it. The period jumps up to 18 seconds, which is a long-period groundswell, but with the onshore wind, it’s not going to shape up well. The energy is still moderate (460), but the comments are all about poor or marginal conditions.
The rest of the week into late August is a battle. We see a building swell, hitting 7ft on Friday the 28th with a 497 energy, and then 10ft on Saturday the 29th with a strong 1166 energy. But the wind is a constant cross-onshore, mostly from the NW at 12 to 18 mph. At 10ft, this is expert-only territory anyway, and with that wind, it’s going to be a choppy, lumpy mess. This setup is honestly more interesting for kite surfing than paddle surfing.
Into the first week of September, the pattern holds. The swell stays up, with periods around 8 to 9 seconds, and the energy stays moderate to strong. We see another 10ft day on September 2nd with 1163 energy, and again on the 5th with an 12ft swell and a massive 1646 energy. However, the wind is still a cross-onshore issue. The water temp is about average for the time of year, so no surprises there.
The best chance we see comes on Saturday, September 5th. The morning shows a 10ft NW swell with a 9-second period, and the wind shifts to a light cross-shore from the SSW at only 6 mph. The energy is very strong (1274). This is the standout window. The light cross-shore wind will make it much cleaner than anything else we’ve seen. It’s still a big swell for the average surfer, but for the experienced crew, this morning session has potential. The afternoon stays similar but the wind goes back to a light cross-on.
Sunday the 6th is your next best look, with an 8ft NW swell, 9-second period, and light cross-onshore winds. The energy is still strong (1102). It’s not as clean as the 5th, but it’s a solid option. The wind is light, so the chop will be minimal.
So, to wrap it up: the whole 16 days are a tricky wind forecast. The only true standouts are the morning of Saturday, September 5th, and the morning of Sunday, September 6th. Mark them in your calendar. Everything else is a case of waiting for a change in the weather.
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.
