The Lowdown
Alright, let’s get into it.
We've got a mixed bag coming up here at Scarborough Beach. The opening window on Thursday morning August 13th has some serious, powerful swell – we're talking a solid 6 ft of long-period groundswell from the WSW, with energy reading a hefty 1787. The wind's light and offshore from the east, so the lines will be clean. This is proper, expert-level stuff, with that 16-second period. The water temp feels about average for the time of year, nothing unusual there. This is the standout session for the early part of the outlook – a true gem for those who can handle it.
The pattern holds into Friday morning August 14th, with another 7 ft WSW swell (energy 1880) and a light offshore breeze making for a clean, punchy morning. Friday afternoon stays clean too, with a nice cross-offshore breeze and energy at 1743.
Saturday morning August 15th sees the swell dip slightly to 6 ft, energy dropping to 1099. It’s clean enough but has a more average feel to it. By Saturday afternoon a light cross-onshore kicks in, so it’ll get a bit rippled.
Sunday August 16th morning is back in the mix with a 6 ft swell, 15-second period, and clean conditions. Afternoon brings a glassy vibe with light NNE winds, keeping it clean.
Then things go sideways for a stretch. Monday August 17th and Tuesday August 18th get messy with strong onshores and serious size. Tuesday sees a 13 ft swell and massive energy of 7278, but it's blowing straight onshore – that's a hard pass for paddling. Wednesday August 19th and Thursday August 20th stay rough, with strong cross-onshores and lumpy, choppy conditions.
We get a bit of a reprieve on Saturday morning August 22nd. A 7 ft WSW, 14-second swell with glassy conditions and light winds – that's worth a look. The energy's good at 1919.
Sunday morning August 23rd is another clean, cross-offshore session with a 7 ft, 16-second swell and energy at 2497. That’s the last proper standout for the first week.
Now, early in the second week, on Tuesday August 25th, there's a big pulse of energy. A 10 ft, 18-second groundswell with glassy conditions and energy at 5830 – this is for experts only, and it's a long way out, so call it promising but not set in stone. Wednesday August 26th is similar, with another 10 ft, 16-second swell and glassy morning, but it's also expert-only territory.
Thursday August 27th morning settles back into a nice, manageable 7 ft, 14-second swell with clean, cross-offshore wind. That's a solid, fun session for the experienced surfer. Friday August 28th gets blown out again, so we finish on a bit of a down note.
To sum it up: the very best windows are Thursday and Friday mornings, and Sunday morning, all in the first week, with clean, long-period groundswell. The big glassy mornings in the second week are huge but only for the brave. Crowds are likely on those cleaner days.

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.
