The Lowdown
Alright, Rusty here again. Let's break this down.
The water temp at Caspar Creek is about 58°F, which is pretty much normal for this time of year. Nothing to write home about.
I'll be blunt – the next 16 days are a tough slog. There's a big ol' gap of nothing good. From Wednesday the 26th through the end of August, it's a no-go. The swell is tiny, with weak wave energy (302), coming from the SW, which is a bad direction for this spot. The wind is a cross-onshore, making it all choppy and messy.
Moving into the first week of September, the pattern is stuck. The wind just won't let up from the NW, and the swell is either too small or, when it does get a bit bigger, it's short-period junk. The energy readings are moderate – like 444 on the 30th of August for a 7ft swell, but it's all wind-affected and lumpy.
There's a tiny glimmer on Friday the 4th of September morning. We get a 7ft swell from the NW with a 10-second period, giving a decent energy reading of 882. The wind is onshore, which is a bit better. But it's only a marginal call, and the rest of the day is back to the same old cross-onshore mess. Saturday the 5th morning is another brief marginal moment, but it's a long shot.
Beyond that, the second week is more of the same. The NW wind is relentless, the swell stays around 5ft to 6ft, but it's all short-period, wind-affected junk. The energy is moderate, but the quality is zero. It's a long, flat, frustrating outlook.
The best of a bad bunch is the Friday 4th September morning. The 7ft NW swell with a 10-second period and onshore wind might offer a brief window. But it's a marginal call at best. Honestly, this whole stretch looks more interesting for the kite surfers than for us.
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.
