The Lowdown
Righto, surfers, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
We’re going to be dealing with a solid, long-period groundswell from the west-southwest, but honestly, this one’s a bit of a beast. The first few days are just too much for most of us, with a big, powerful swell pushing through. The water is a bit colder than normal for this time of year at 63°F, so grab a decent rubber.
The standout by a country mile is Thursday morning the 20th of August. Scarborough Beach will be pumping with a 8ft swell from the west-southwest, a glassy, dead-calm wind, and a very long 16-second period. This is proper groundswell, packing a ton of energy (3351) and offering the best quality of the entire run. It’s built for experienced surfers – the power is real, and the shape should be excellent. You’ll want to be out there early.
Friday morning the 21st is also a good call, with a clean 7ft swell from the same direction and a light offshore easterly breeze. The period drops a little to 15 seconds, but it’s still a very solid option. You’ll have the place to yourself crowd-wise, too.
The following week is a mixed bag. The swell stays in the 5ft to 8ft range, but the wind is often cross or cross-on, and the quality only gets good for a few moments. Monday morning the 24th and Wednesday morning the 26th both have glassy periods with 7ft and 7ft swell respectively, those are your best bets for a clean session. Friday morning the 28th also has a clean 7ft option with a light offshore.
By the time we hit the end of the month and into September, the wind turns against us, and the swell gets big and messy again. The 30th and 31st look poor, and the 1st of September is a no-go with a 13ft onshore mess.
Crowds are only a real worry on the absolute best days, but the rest of the time it’s pretty quiet out there.
Rusty.

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