Alright, let’s break it down for Caspar Creek in feet and miles per hour.
It’s been a slow start, real quiet. The first few days here are looking like a write-off, with mostly cross-onshore winds and poor conditions. The water’s a bit colder than usual for this time of year, about 54°F.
We’ve got a few days of nothing worth paddling for through Friday and Saturday the 17th and 18th. The swell is tiny, the wind is messy, and the energy is weak. The best of the weekend is Saturday morning, the 18th, with a light cross-onshore breeze and a marginal 3ft swell from the WNW (16 seconds). The combined energy is moderate at 1018, but it’s just not clean enough to get stoked on.
Things look a little more promising on Monday the 20th. The afternoon brings a real highlight: glassy conditions with a 3ft swell from the SW at 16 seconds. The combined energy is moderate (606), and that glassy wind will make for a clean, smooth surface. This is the best on offer in the first week, but it’s a small, slow-moving groundswell – more of a log session than a shortboard burner.
The rest of the first week and into the second week is a tough stretch. From Tuesday the 21st right through to the end of July, the forecast is mostly cross-onshore winds and poor surf conditions. The swell does build, but the wind stays on it, making it a mess.
Now, for the long-range, we’ve got a couple of interesting standouts that are promising but less certain. On Thursday the 30th of July, the swell builds to 8ft in the morning and 12ft in the afternoon from the NW, with a period of 8-9 seconds. The combined energy jumps to strong levels (1698 and 1945). But the wind is still cross-onshore, and the surf quality is only marginal. This is expert territory at 12ft. The following day, Friday the 31st, the swell holds at 10ft to 12ft, with strong energy (1612 and 2060). The wind is a little lighter in the morning, which is a positive, but it’s still cross-onshore. This one is for the experienced crew only.
The biggest swell of the outlook hits on Saturday the 1st of August, with a 10ft NW swell and a very strong energy reading of 2535. But the wind picks up to a moderate cross-onshore, making it choppy and marginal. It’s a real shame, because the size is there, but the wind is going to ruin it.
So, to wrap it up: the standout for clean conditions is Monday afternoon the 20th of July, but it’s small. The biggest surf comes at the end of July and start of August, but it’s all blown out. For the experienced surfers, the 30th and 31st of July and the 1st of August offer size, but don’t expect perfection.

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.
