The Lowdown
Alright folks, Rusty here. Let’s take a close look at what’s on the table for Caspar Creek over the next couple of weeks. Straight up, this is a tough one – we’re looking at a long stretch of meh before anything gets interesting.
For the first week and a half, from Monday the 7th right through to Saturday the 19th of September, it’s a real bummer. The surf is on offer, but it’s consistently tagged as poor surf conditions. The wind is a constant cross-on breeze, never giving us a break. The swell is there, but it’s small and messy, with short periods of 7 to 8 seconds, meaning the waves lack any real punch or shape. The combined energy is weak to moderate at best, with values mostly in the hundreds (128, 156, 232, 637). Water temp is sitting at 59.9°, which is about average for this time of year, so no surprise there. Honestly, for a consistent spot like Caspar Creek, it’s a frustrating run of onshore slop.
Around midday on Sunday the 20th of September, things start to change. The swell kicks up significantly, with an 11.5ft swell from the NW and a period of 9 seconds. The combined energy jumps to 2041, which is strong. But the wind is still a moderate cross-on, making it choppy, and the forecast is only marginal. This is a big, raw swell – definitely for experienced surfers only, as it’s well over 8ft.
The real standout, the only one worth getting excited about, is on Tuesday the 22nd of September afternoon. We finally get a glass-off. The wind goes completely calm, the wave state is glassy. The swell is a solid 5.2ft from the NW with a period of 10 seconds, producing moderate energy of 823. This is the best window of the entire 16-day forecast. The waves will be clean and lined up. This is the one to aim for, but keep in mind Caspar Creek is a sheltered spot, and with the long period of 10 seconds, it should handle that well.
The days leading up to that have some larger swells (7.5ft, 11.5ft) but all with wind and chop. The final day, Tuesday the 22nd, is your best bet. It’s the only time the conditions truly align for a good session.
Short Range ForecastMostly dry. Warm (max 23°C on Wed morning, min 13°C on Mon morning). Wind will be generally light. | Days 4-6 Weather SummaryMostly dry. Very mild (max 19°C on Thu morning, min 11°C on Sat night). Winds increasing (calm on Thu night, fresh winds from the NW by Sat afternoon). | ||||||||||||||||||||

A general guide to surfing at Caspar Creek can be found by selecting the local surf guide option on the grey menu.

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.
