The Lowdown

Alright, let's get into it. The next couple weeks are a bit of a mixed bag really. The main spot on the cards is Caspar Creek. The water's hanging around 55°F, which is a bit colder than normal for this time of year, so you'll want a good 4/3.

First up, early September has some swell around but the wind's just not playing the game. Friday the 4th sees a moderate 6ft NW swell rolling in, but it's got a cross-onshore wind and feels pretty messy, with moderate energy levels (651). The vibe is poor. Saturday the 5th is a bit smaller at 5ft, but the wind is still onshore or cross-on. This pattern pretty much holds through the whole first week. There's a small glass-off window on Friday the 11th with 2ft swell and glassy wind, but it's tiny. For the most part, we're looking at a solid stretch of overall poor to marginal conditions with no real standout sessions in that first week.

Into the second week, things get a little more interesting for the crew who don't mind a bit of size and mess. Monday the 14th morning has a 5ft NW swell, and while the wind is cross-on, it's light, and the energy is moderate (437). The forecast notes it as marginal. Then we see a definite pulse building toward the end of the window. Thursday the 17th morning has a 6ft NW swell with light onshore winds, giving us marginal conditions and moderate energy (544). This swell builds into Friday the 18th, with 7ft to 7ft NW swell. The morning of the 18th is the real stand-out with light cross-onshore winds and high energy (922). That's a punchy, powerful wave for sure. This is what we're waiting for. It's right on the edge of being a handful though - 7ft is a solid wave, so it's for intermediates and above.

Saturday the 19th drops right off into a long-period 2ft SW groundswell, so the window closes quickly after that.

So, the one true standout in this 16-day window is Friday the 18th of September at Caspar Creek. It's not perfect – it's cross-on – but with that 7ft NW swell and that strong energy reading (922), it's the biggest and most powerful offering we get. It'll be a wild one for those who are keen.

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.
