The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a pretty tough stretch ahead for Caspar Creek. The whole 16-day window is plagued by persistent cross-onshore winds and a swell direction that’s coming straight from the NW, which is the same as the optimum for this spot, but the wind is just ruining it. The water temp is about average for this time of year, nothing wild there.
The first few days are a write-off. Friday the 7th and Saturday the 8th are just poor, with chest-high to slightly overhead swell but completely chopped up by a steady NW breeze. You’re looking at 3ft to 8ft of swell, but the energy is moderate (133 to 660) and the cross-on wind makes it a mess. Not worth paddling out.
Sunday the 9th gets bigger, 8ft to 10ft, with a moderate cross-on wind and combined energy climbing into the strong range (964 to 1391). That’s too big for beginners and the chop will be nasty. That’s more of a kite-surfing setup than a paddle session.
Monday the 10th through Wednesday the 12th is a little more promising, but still not good. Swell hangs around 7ft to 8ft, with light cross-onshore winds and a period of 9 seconds. The combined energy swings from moderate to strong (686 to 1912), and the wave comment is “marginal” at best. The wind is lighter, so the surface might be slightly cleaner, but the cross-onshore direction still kills the quality.
Thursday the 13th through the rest of the week sees the swell drop. We’re looking at 4ft to 6ft with light winds, but the energy is weak to moderate (145 to 884) and it’s still cross-onshore. The waves aren’t going to have any shape.
From the 16th of August onward, the swell gets small and weak. On the 16th, we’re down to 1ft to 2ft, with weak energy (48 to 58) and onshore winds. Not surfable. The 17th sees a bump to 5ft to 6ft with light onshore wind, but the energy is still moderate (287 to 521) and it’s marginal at best.
The 18th to the 22nd of August is a slow fade. Swell is 3ft to 6ft, period is short (7 to 12 seconds), and the wind is always cross-onshore. The combined energy stays weak to moderate (166 to 614). The 20th of August has a long-period 12-second swell from the WNW, but with a moderate cross-onshore wind, that’s just a messier, more powerful chop.
There is no standout session in this entire forecast. The wind never gives us a break. The only half-decent chance might be Tuesday the 11th or Wednesday the 12th, when the swell is solid and the wind is light, but it’s still cross-onshore. If you’re an absolute die-hard, you could paddle out on one of those mornings and find a few, but it’s not going to be good.
Honestly, this is a long blank run. For Caspar Creek, this kind of persistent cross-onshore slop is pretty normal. Forecasts can change, but right now, it’s a tough call.
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.
