The Lowdown
Alright folks, Rusty here. Let’s get into it. We’re looking at a real mixed bag for our corner of the coast. The next 16 days kick off with some solid swell but the wind is just not playing ball. We’ve got a lot of cross-onshore breeze messing things up, especially early on. It’s a bit of a patience game, with a few windows where the conditions clean up nicely towards the end of the second week.
The first few days from Sunday the 9th through to Tuesday the 11th are a write-off in terms of quality. Sure, we’re seeing some decent sized NW swell, pushing 8ft to 8ft, but that moderate cross-onshore wind at 12 mph on Sunday is kicking up a proper chop. Wave energy is moderate to strong (823 to 2049 on the energy scale), but it’s ugly out there. Monday morning has the biggest energy reading of the whole period at (2049), but the wind is still cross-on. This isn’t a time to paddle out unless you’re after a beating.
We finally catch a bit of a break Wednesday the 12th and Thursday the 13th. The swell drops slightly to a still punchy 7ft to 7ft from the NW. The real story here is the wind. On Wednesday morning, we see that 3 mph wind from the West, which is straight onshore, but with the light air, it’s not too terrible. By Thursday afternoon, it’s clear skies and the swell is 6ft. It’s still marginal, but you could find a few. The wave energy is still moderate (459 – 829).
Now, if you want the real standout of the whole forecast, you have to look a bit deeper into the second week. The swell drops right off for a few days from the 14th to the 17th, with heights barely hitting 3ft. That’s a real lull.
Then things get interesting. On Tuesday the 18th, it’s small, but the conditions get *real* clean. The morning is a bit cross, but the afternoon turns glassy. The swell is only 2ft from the WNW with a period of 13 seconds. That’s a long period groundswell (259 on the energy scale). With glassy conditions, Caspar Creek could have some fun, clean little walls for a log or a fish. It’s a sheltered spot, so that long period NW/WNW energy should wrap in nicely.
But the real *best on offer* is a bit of a punt. Looking all the way out to Saturday the 22nd of August. The swell jumps back up to 8ft from the NW. The wind is still cross-on from the NW at 9 mph, which is a problem, but the energy is high (1194). The morning is marked as marginal, not poor. If that breeze eases, you’re looking at some powerful, solid NW lines. For the experienced crew, this is the one to circle on the calendar. It’s a week and a half out, so don’t book the day off yet, but keep an eye on it. Anything over 8ft is strictly for experts anyway.
Following that, the 23rd and 24th see the swell back down with some weird long-period SW swells coming in, but the size is too small to make much of.
So to wrap it up: the first week is mostly wind-blown junk. The best chance for a genuinely clean, glassy session is that Tuesday the 18th afternoon, even though it’s small. The biggest hope for size and power is that Saturday the 22nd morning, but it’s a long way off and the wind has to behave. Stay tuned.

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.
