The Lowdown
Alright folks, Rusty here. We’re taking a hard look at the only spot that’s shown up on the radar for this 16-day window: Caspar Creek. Let me tell you straight up, it’s a tough run ahead.
The overall pattern for the next week and a half is pretty grim. For the first week, from Tuesday afternoon right through to the end of the first week of September, it’s all "poor surf conditions" with nothing worth paddling out for. The swell is small, the winds are cross-on, and the wave energy is weak. There’s a long wait coming.
The first real glimmer of hope doesn’t show up until Friday the 4th of September morning. The swell finally kicks up to 8 ft from the NW with a 10-second period, giving us moderate to strong energy (1090). But it’s only "marginal" at best. By Friday afternoon, the wind switches to onshore light from the west, but the forecast still says it’s questionable. It’s not the clean day we dream of.
Now, the standout moment – and the only one worth circling on your calendar – is late in the run. On Monday the 7th of September afternoon, we see a solid 12 ft NW swell (very strong energy at 2757) with a long 10-second period. The wind is a light cross-on from the SSW. This is big, powerful groundswell, but the period is long so Caspar Creek will be fat and bowling, top to bottom. The water temp is around 58°F, which is pretty average for this time of year. Conditions are still "marginal" though. Then, best of the bunch, Tuesday the 8th of September afternoon looks to be the real deal. The swell settles to a still-chunky 7 ft from the NW, the period holds at 10 seconds, and the wind goes glassy – a light offshore from the SW. That’s a rare, clean window with moderate to strong energy (817). Caspar Creek is a sheltered, consistent beginner spot, and it's often crowded, so expect company if you score this one. This is the one day to go.
Tuesday the 8th of September afternoon at Caspar Creek is your best bet: 7 ft NW, glassy conditions, and a long period groundswell. Don't sleep on it, but don't expect perfection the rest of the window. This is Rusty, signing off.

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.
