Table - best surf conditions forecast for Kalk Bay Reef over the next 16 days.
Alright, Rusty here. Let's take a look at what's coming up for Kalk Bay Reef.
Right off the bat, I gotta be straight with you: this spot is a tough one. It's a reef break that rarely breaks, and even when it does, it's only for the advanced crew. The ocean's running warm, about 60°F, which is pretty much average for this time of the year, so nothing weird going on there.
We've got a long wait ahead. The first real chance for a wave won't be until Monday morning, the 13th, and even then it's just a small, 3ft south swell with a short 10-second period. The energy is weak (191), and honestly, it's not much to write home about. But Monday afternoon improves a little; the glassy wind will make it look clean, with the same small swell, so it's a chance for a quiet paddle if you're desperate.
The first proper standout comes on Wednesday morning, the 15th. We've got a 5ft SW groundswell with an 11-second period, and the energy is up to moderate (662). The wind is light and cross-offshore, so it should be clean. This is the first time things look genuinely good.
But the real highlight, the one to circle on your calendar, is Thursday the 16th. Both morning and afternoon are firing for experienced surfers. We're looking at a solid 8ft SW swell in the morning, and 8ft in the afternoon, with a 13-second period. The energy is strong (2281 and 1697). The wind is light and cross-offshore, keeping it clean. This is well over 8ft, so this is strictly for experts – this reef will be throwing out some serious, powerful lines. This is the best of the whole forecast.
After that, things get messy again. Friday the 17th is a write-off with strong onshore winds. There's another potential window on the 18th and 19th, with the 18th afternoon looking particularly nice with glassy conditions and a clean 4ft south swell, and Sunday the 19th afternoon offering clean offshore winds on a smaller 4ft swell.
After that 19th, there's a long gap of poor wind and lumpy conditions stretching through the 20th, 21st, and most of the 22nd. We get some size back on the 22nd and 23rd, but the wind is consistently cross-onshore, turning what could be good waves into a choppy mess. It's honestly looking more interesting for kite surfing than paddle surfing during that stretch.
So, to sum it up: Thursday the 16th is your day. Don't miss it. The rest is a waiting game for the right wind.
Rusty.

The above surf forecast table for Kalk Bay Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kalk Bay Reef can be found by selecting the local surf guide option on the grey menu. Our Kalk Bay Reef 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.

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 Kalk Bay Reef 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.
