The Lowdown
Alright, Rusty here, talking Caspar Creek. Water’s sitting at 55°, that’s way colder than usual – more than 4° below the norm. You’ll want a thick suit.
The first decent session won’t hit until Thursday the 3rd. The afternoon goes glassy – zero wind – with a 6ft NW swell at a 10-second interval. Energy runs moderate (826). It’s small but clean, so you can get a few.
Friday the 4th morning shows bigger swell at 7ft from the NW, 11-second period, and strong energy (963). But the wind is cross-onshore, so the surface gets bumpy.
The real standout is Thursday the 10th afternoon. Glassy again, with a 5ft NW groundswell at a long 12 seconds. Energy spikes to 1080 – a strong pulse. Clean, powerful, and at a sheltered spot, it’ll have some nice roll.
Friday the 11th is still clean in the morning – 5ft NW at 13 seconds, energy at 977. Another good one, but the afternoon gets a little messy.
From the 13th on, it’s mostly cross-onshore breezes and choppier conditions. The 14th afternoon sees 8ft and 967 energy, but the wind is poor – too big and rough for anything but a serious crew.
Bottom line: the 10th afternoon through the 11th morning is your window. The rest is waiting.
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.
