The Lowdown
Alright, let’s get into it. This is a tricky outlook for our stretch of coast. The 16-day window starts off rough, and honestly, it’s a long wait for anything solid. We’ve got Caspar Creek as the only spot on the radar, but it’s a sheltered beginner-friendly wave, so don’t expect much punch. The water’s sitting at 57°, which is about average for this time of year, no real surprises there.
The first week is pretty much a write-off. From Saturday, the 29th of August through the end of the month, we’re looking at poor surf conditions. The swell is mostly 5ft to 8ft from the NW, but it’s short-period stuff (7 to 8 seconds) and the wind is cross-onshore, mostly from the NW at 12 to 19 mph. That means chop and slop, not rideable. The combined energy on Saturday afternoon hits 606 (moderate), but it’s wasted with that wind. For a beginner spot like this, the 8ft swell on Saturday afternoon is too big for learners anyway.
Sunday the 30th morning has a bit of a pulse with 7ft NW swell and 1111 energy (strong), but it’s still cross-onshore and lumpy. Not worth paddling out. The rest of the week into early September stays poor, with tiny swell (2ft to 4ft) and onshore winds. Energy drops to 135 on Tuesday morning—weak stuff.
Now, there’s a glimmer on Thursday, the 3rd of September. The morning is glassy—dead calm—with a 3ft swell from the SW and a very long 19-second period. The combined energy is 831 (strong). That’s a groundswell with real shape, but it’s small, and for a sheltered spot like Caspar Creek, that long period might make it break a bit too straight. Still, glassy conditions are rare here, so if you’re a beginner, this is your morning. The water’s still around 57°, no change.
After that, we’re back into a poor pattern with cross-onshore wind and moderate to fresh NW winds (12 to 22 mph) through the 6th of September. The swell is 4ft to 6ft, but the combo of wind and short period (7 to 9 seconds) keeps it messy. Energy is moderate, peaking at 606 on Friday the 4th afternoon, but it’s lumpy.
There’s another gap of poor conditions into the second week, with tiny swell and onshore breezes. Then, on Wednesday, the 9th of September, the afternoon looks promising. We’ve got a 6ft NW swell with a 12-second period, calm glassy wind, and strong energy at 1013. That’s the standout of the whole outlook. The swell direction is NW, which is the optimum for Caspar Creek, and it’s a moderate size—good for intermediates but not too big for beginners. The long period (12 seconds) should give some decent shape, and with zero wind, it’ll be clean. This is the best session on offer, but it’s over a week away, so keep an eye on the forecasts.
The rest of the second week fades out. Thursday the 10th morning has a 5ft NW swell at 11 seconds but marginal tide conditions and light onshore wind. Friday the 11th morning brings a 3ft SW swell with a very long 16-second period and 811 energy, but it’s cross-onshore, so it’s not clean. The final days (12th to 13th) are small and messy, with southerly wind and low energy.
Overall, this is a patchy run. The surf tends to be inconsistent here, so a blank spell isn’t unusual. The one real standout is the afternoon of Wednesday, the 9th of September—glassy, solid energy, and good swell direction. That’s your best bet. For the rest, it’s a waiting game.

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.
