The Lowdown
Alright folks, Rusty here. Let’s get into it.
Alright, we’ve got a real mixed bag coming up at Scarecrows. This is a reef setup, so it’s one for the advanced crew only. The water is a touch warmer than normal for this time of year, sitting at 86°.
The first decent window doesn’t really show up until later in the week. The early part of the period is a write-off. Tuesday the 21st and Wednesday the 22nd are poor with strong, messy winds and weak, short-period swell. We’re talking marginal surf at best, with scores that reflect that. The combined energy is weak to moderate, sitting around 1006 and 882. Not worth a paddle.
Thursday the 23rd and Friday the 24th see a slight bump in swell height to 6ft – 6ft, but the wind is howling at 16 mph from the cross-off and cross directions, ruining any chance of a clean face. The energy picks up a bit – 684 to 850 – but it’s still a messy, blown-out proposition. The weekend isn’t much better, with rain and cross-shore winds keeping quality low.
Now, here’s where it gets interesting. A glassy, clean morning pops up on Monday the 27th. The wind is dead calm from the east at 3 mph, and the swell is a small 4ft from the SSE. The energy is low (381), but the clean conditions are a major positive. It’s a tiny window, but it’s our first real sign of life.
The real standout, the one you’ve been waiting for, is Thursday the 30th of July. We’ve got a 4ft groundswell from the SSW with a very long period of 19 seconds. The combined energy is a strong 1235. The wind is a light, cross-off breeze from the ESE. This is excellent, clean surf for experienced surfers. The long period will make the waves stand up and pulse through, but being a reef, it should handle that energy beautifully. The only caveat is that this is a long period swell, so expect longer lulls between sets.
Friday the 31st keeps the quality going. Another 4ft SSW swell with a 17-second period, light cross-off wind, and energy of 1134. More excellent conditions for the experienced crew.
The run of quality continues into the first week of August. Saturday the 1st is still clean and fun, but the real beast is Sunday the 2nd. The morning is a solid 4ft S swell with a 17-second period and massive energy of 1504. But the afternoon is the pick of the entire forecast. The wind goes glassy, the swell jumps to 6ft from the SSW, and the combined energy hits a massive 2423. That’s a serious pulse of energy. This is expert territory, no question.
Monday the 3rd keeps the swell train rolling with 6ft S swell, clean cross-off winds, and energy of 1526. Again, experts only. Tuesday the 4th is still excellent with a 4ft SSW swell, 18-second period, and 1655 energy. The quality persists through the 5th, though the wind starts to become more cross-shore.
So, the best on offer is a tie between the glassy afternoon session on Sunday the 2nd of August, and the excellent, clean mornings on Thursday the 30th and Friday the 31st of July. If you’re an experienced surfer, those are the sessions to lock in. Just remember, Scarecrows is a crowd magnet, so expect company.
Rusty.

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