The Lowdown
Gutted to be starting the outlook with a flat, grey picture at Caspar Creek. That water’s sitting at 56°, which is a bit colder than normal for this time of year – don't forget the hood. The energy’s weak to start, only around 237 on the combined swell scale Tuesday morning, and with a stiff cross-onshore breeze, it's going to be a messy, poor surf day. We’re looking at a blank run here for the first couple of days.
The one real bright spot in this whole 16-day window, and it’s a long way off, is Monday the 24th. The wind drops right out to glassy and that south-west swell eases down to 2ft with a long, 18-second period. It’s a chance for a few clean, lined-up waves at a sheltered spot, but it’s a long-range call, so don't book your life around it. The swell is small, but the calm conditions will make it look a hell of a lot better than anything else on offer. It’s your standout, no question.
Before that, the weekend is a bit of a no-go. The energy picks up to moderate numbers, between 400 and 624, but it’s still that cross-onshore wind chopping it all up. We’re talking about a solid week of poor conditions, from around the 18th through to the 23rd.
After the 24th, the wind swings back onshore and we’re back into the messy stuff. The swell comes up again towards the end of the month, with the energy climbing into the strong territory. On the 30th, the combined energy rockets to 1158 and you’re looking at a 10ft cross-onshore swell. That's proper, powerful, and blown-out. At that size, it’s experts only, maybe even more interesting for the kite crew than the paddle crew. The wind just ruins the wave quality, keeping the scores low. It’s a case of waiting for that one clean window on August 24th and hoping the long-range call comes in.

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.
