The Lowdown

Alright, Rusty here. Let’s talk about what’s on the cards for the next couple of weeks.

Right now, things are pretty quiet. The start of the outlook is a bit slow, but there’s a real standout coming up. We’ve got a reef break that needs a decent swell direction, and it’s a touch inconsistent, but when it fires, it’s worth the wait.

The first real action kicks off Thursday morning, August 6th, with a small 3ft southwest swell, but it’s got a cracking 12-second period and nice offshore wind. The water temp is about average for this time of year, so nothing unusual there. The combined energy is weak (277), so it’s more of a longboarder’s session. It’s clean, but not going to blow your mind.

By Friday afternoon, August 7th, things start to look tasty. The swell picks up to 4ft from the southwest, and the period stretches to 15 seconds – proper groundswell energy. The wind goes glassy, and the combined energy jumps to moderate (1195). That’s a sweet spot for Summerland Bay. It’s an intermediate break, so the size is friendly, and those long-period lines will be holding up nice on the reef. Crowds are possible here, so don’t be surprised if a few others have the same idea.

Saturday, August 8th, is a write-off. Strong north winds and a drop in energy make it a mess.

Now, here’s the big one. Monday morning, August 10th, we get a serious pulse: 12ft from the southwest with a very long 19-second period. That’s a massive groundswell. The combined energy rockets to very strong (8501). This is expert territory only – over 8ft is for the experienced crew. The wind is cross-off, which keeps it clean, but that size and period will be charging through. This is the standout. It’s a reef break, so it should handle the long-period swell well, but it’s going to be a beast. The morning session is the pick, as the afternoon drops slightly to 10ft.

The days after that are a mixed bag of messy wind and smaller swell, with a few windows of cleaner, manageable waves around the 7ft to 8ft mark on Thursday, August 13th and Friday, August 14th. Those are good for experienced surfers, with clean conditions and decent energy levels (around 2325-4547), but they don’t quite match the intensity of that Monday stand-out.

There’s another promising run on the 20th and 21st of August. Thursday morning, August 20th, sees a 7ft southwest swell with a 15-second period and clean cross-off wind. That’s solid, and the energy is moderate (2894). Then Friday morning, August 21st, the swell picks up to 8ft from the west-southwest, with a shorter 12-second period but strong offshore wind. The combined energy drops to 1505, but that offshore wind will make for some clean, hollow take-offs. Crowds are possible, so get in early.

All in all, the absolute best is Monday, August 10th, for the experts. For the rest of us, Friday afternoon, August 7th, and the 20th-21st windows are the ones to mark.

Rusty.

Information about the Summerland Bay Surf forecast

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