The Lowdown
Alright, folks, Rusty here. Let’s get straight into it. I’ve been staring at the charts for Caspar Creek and, well, it’s a tough one. For the first week and a half, there’s really nothing to get excited about. The wind is constantly cross-on, and when the swell does pick up, it’s coming straight from the north-west with a period that’s not doing us any favours. The wave energy is all over the place, but it’s not translating into anything rideable with a clean face. You’re looking at a long stretch of poor to marginal conditions.
Thursday 6th August kicks off with a tiny 2ft south-west swell, but it’s got a 13-second period and a light cross-onshore breeze, so it’s just bumpy and messy. That sets the tone for the next few days. Into Friday 7th and Saturday 8th, the swell builds from the north-west, hitting 5ft on Saturday morning and climbing to 8ft by the afternoon. The wave energy is ramping up, from 163 to 327 to 737, but it’s all for nothing with that steady cross-onshore wind. It’s just choppy, bumpy junk.
Sunday 9th August sees the swell go over 8ft, hitting 10ft by the afternoon. The wave energy is strong, over 1500, but that moderate cross-onshore wind is making it a mess. For a beginner-friendly spot like Caspar Creek, this is too big and too messy. This continues right through Monday 10th, Tuesday 11th, and Wednesday 12th, with swell holding around 10ft to 12ft. The energy is massive, peaking at nearly 2000, but the wind is relentless. It’s more of a kite-surfing setup than a paddle-surfing one.
We finally get a shift on Thursday 13th August. The wind turns directly onshore, from the west, but it’s light. The swell drops to 7ft and the energy is still moderate (967). The conditions are still only marginal, but for the first time, it’s not completely blown out. Friday 14th and Saturday 15th see the swell drop further, down to 4ft, with light onshore winds. The energy is low, around 142 to 157. The water temperature is sitting at 56°, which is a touch cooler than usual for this time of year, but nothing too wild.
After that, it’s a long, flat run. From Sunday 16th August right through to Friday 21st August, the swell is mostly under 3ft, with wave energy dropping to as low as 37. The wind stays cross-on, and honestly, it’s just a dead period. You can leave the board in the shed.
So, looking at the whole 16-day window, there is no standout. The best you’ll get is the marginal window on Thursday 13th and Friday 14th August, when the swell is still decent around 7ft to 7ft, and the wind is light onshore. It’s not clean, but it’s the only time you could maybe scratch into a few. For a consistent spot, this is a rough run, but the forecasts can change, so keep an eye on it.
Rusty.

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.
