The Lowdown
Alright, I’m Rusty, and I’ve been staring at the charts for this little stretch of coast. Let’s be straight with you: the next 16 days are a tough watch for Caspar Creek. This spot is a sheltered beginner wave, and it’s usually consistent, but this forecast is a long, flat, and choppy grind. There’s a real gap in quality surf here, with almost the entire period offering nothing but poor conditions. The water temp is sitting about average for the time of year, nothing weird there.
We start off on Wednesday, August 26th, with tiny 2-foot SW groundswell pushing through at a long 16 seconds, but the wind is cross-on from the NW, light at 6 mph, leaving it bumpy with small wind ripples. The combined energy is weak at 301, and it’s just poor. That theme carries through Thursday and into Friday, August 28th, when the swell bumps up to 5-foot from the NW, but the period drops to a short 7 seconds, and it’s still cross-on and choppy. By Friday afternoon, the swell hits 7-foot, but with that short period and messy wind, it’s a washout – the energy is moderate at 495, but it’s all chop.
The weekend stays the same. Saturday morning, August 29th, has 6-foot NW swell, 7-second period, and cross-on wind. The combined energy is 287. Sunday morning, August 30th, is the first time we see a “marginal” rating, with 7-foot NW swell, 8-second period, and light cross-on wind from the WNW at 6 mph. The energy is 480. It’s still not clean, but it’s the least bad option in the first week. The rest of the week is a write-off.
Into the second week, from Monday, September 1st, there’s almost nothing. Swell drops to 2-foot on Tuesday, September 1st, with very weak energy at 35. A small pulse of 5-foot NW swell shows up on Wednesday, September 2nd, period 9 seconds, but the wind is still cross-on, and the energy is moderate at 509. It’s still poor.
The only real standout, and I’m being generous, is Friday, September 4th. The morning has a 8-foot NW swell, 10-second period, and for the first time, the wind is onshore from the west at 6 mph, but it’s light. The energy is strong at 1069, and it’s rated marginal. That’s the biggest, most powerful swell of the whole run, but it’s for experts only – that’s a big wave for a sheltered beginner spot, and with the wind on it, it’s going to be a beast. It’s promising if you’re a charger, but it’s far out and not a sure thing.
The rest of the run after that fades back into tiny, weak, choppy conditions. Through September 7th, 8th, 9th, and 10th, it’s all 2-foot to 5-foot, short period, and cross-on wind. The energy stays weak to moderate. On Wednesday, September 9th, there’s a weird 2-foot SW swell with a very long 24-second period, but the wind is a moderate 12 mph cross-on, so it’s just messy.
In short, this is a blank run. For a spot that’s usually consistent, it’s a rough stretch. The only flicker of hope is that Friday, September 4th morning, but it’s a long way off and the wind isn’t doing any favours. I’d keep an eye on that one, but don’t get your hopes up. The rest of the time, it’s either too small, too choppy, or too short-period to bother with. Conditions like this would be more interesting for kite surfing than paddle surfing with that constant cross-on wind.
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.
