The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
We’re looking at Scarecrows, a reef break that’s for the advanced crew only. The water is sittin’ at a warm 85°, which is a touch above the norm for this time of year – not crazy, but you’ll notice it. The overall pattern is a long, drawn-out run of mediocre surf with a couple of promising windows. The combined wave energy kicks off around 1018 (moderate) and builds to some serious numbers later on, but the conditions are gonna be a real mixed bag.
First up, the opening days. Monday the 7th and Tuesday the 8th are a bit of a write-off. The swell is around 3ft to 4ft out of the SSW, but the winds are a cross or cross-off from the SE, so it’s not total junk. The energy is moderate (1018 to 1046 on Monday), but the wave comment is calling it marginal surf. Nothing to get excited about.
Wednesday the 9th and Thursday the 10th see the swell bump up to 5ft to 5ft, still SSW. The wind is a clean cross-off in the mornings, and the energy is picking up – we’re seeing 1455 to 1658 (moderate to strong). There’s a risk of thunderstorms, but the mornings are offering clean surf. It’s still not the best, but it’s a step up.
The real standout in the first week is Saturday the 12th through Sunday the 13th. The swell is hitting 6ft to 7ft from the SW, with a long period of 17 to 19 seconds. That’s proper groundswell fellas. The combined energy surges to 2054 on Saturday morning and 3015 on Saturday afternoon – that’s strong. The Saturday morning is clean with a cross-off wind. Sunday morning is also clean with a cross-off, but the swell is 7ft. That’s getting up there, so it’s only for the experienced. For the rest of you, this is a good time to watch from the rocks.
The middle of the week, Monday the 14th through Wednesday the 16th, is a bit of a lull. The swell drops back to 5ft to 6ft, and the winds turn more cross-shore with a chop. The energy drops to around 994 to 1686. It’s not great, but it’s not flat.
Now, hold onto your boards. The second week has a couple of crackers. Thursday the 17th is a standout morning. The wind is a clean offshore from the NE at 15 mph, and the swell is 6ft from the SSW with a 15-second period. The combined energy is 1889 (strong), and the wave comment says “excellent surf conditions for experienced surfers.” That’s the one. That morning is the pick of the first half of the fortnight.
Another one to circle is Saturday the 19th. The morning is clean with a cross-off from the SE, and the swell jumps to 7ft from the SSW. The energy is 2260 (strong). Sunday the 20th morning is also clean, with a 7ft SSW swell and 1697 energy. The wave comment says “excellent surf conditions for experienced surfers.” These are the days you want to be in the water.
The final run from Monday the 21st to Tuesday the 22nd is a bit of a fade-out. The swell drops to 4ft, and the period is all over the place – 13 seconds on Monday, then a long 22-second groundswell on Monday afternoon but with a tiny 2ft height. The energy is moderate. Tuesday the 22nd morning has a 4ft swell with a 20-second period, but the wind is a light cross-onshore. It’s not the main event.
So, to wrap it up: The best on offer is the morning of Thursday the 17th with that offshore wind and solid swell, and the mornings of Saturday the 19th and Sunday the 20th for the bigger, clean SSW groundswell. The rest of the time is a bit of a grind, but those few sessions are worth the wait.
Rusty out.

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.
