The Lowdown

Alright, let’s talk this one out. This is Rusty, and I’m lookin’ at Slade Bay/Boot Reef over the next 16 days, and I gotta be honest: it’s a real dry spell. No standout waves worth chasin’. The energy is mostly weak, with a couple of days of moderate push, but the quality never shows up. There’s a long stretch of poor conditions right through the middle.

We start on Tuesday the 21st. The water is 69°, which is a whopping 9° warmer than usual for this time of year – that’s very unusual, feels like a warm bath. The surf? A tiny 0.3ft swell from the west with a weak 3 combined energy. Nothin’ to ride.

Wednesday the 22nd is a little better with 0.7ft, but still flat. The morning has a nice offshore wind from the north at 9 mph, so the surface is clean, but there’s no wave to catch.

Thursday the 23rd morning is glassy – zero wind – but it’s a 0.3ft swell from the SW with a 15-second period. That’s a long-period nothing-burger. Combined energy is only 14. No break.

The rest of the week into the weekend is the same story. The swell barely hits 3ft on Saturday the 25th afternoon, but it’s a short-period 4-second windswell from the west – all chop and no shape. Combined energy is 22, still weak.

Sunday the 26th shows a little life. Morning brings 3ft from the west, 6-second period, with a cross-offshore wind from the WNW at 12 mph. Combined energy is 74 – weak, but it’s the biggest we’ve seen. The afternoon pushes to 4ft, 85 energy, but it’s still a windswell. The wind stays cross-off, so it’s clean, but the waves will be soft.

Monday the 27th morning is the closest we get to a pulse, with 4ft from the west, 7-second period, and combined energy hits 123 – that’s moderate. But the wind is cross-shore at 12 mph, bringin’ chop. It’s surfable on a log, but not pretty.

The rest drops off. Tuesday the 28th goes to 2ft, and by Thursday the 30th we’re back to 0.7ft. Winds get ugly – cross-onshore and onshore, with rain rollin’ in by the 31st. On the 31st Friday, we’ve got 19 mph onshore winds from the SSW and light rain – a total washout.

Into August, Sunday the 2nd afternoon has 4ft from the SW, 6-second period, with 129 combined energy – the highest in the whole run. But it’s still a short-period windswell, and the wind is cross-off at 16 mph, so it’s clean but weak. The swell direction is SW, which doesn’t match the optimum SW direction, so it’s meh.

Monday the 3rd morning is glassy with 3ft, 7-second period, and 68 energy. The cleanest day of the second week, but still tiny.

If you gotta paddle, the best of the bunch is Sunday the 26th or Monday the 27th, but that’s only for the most patient longboarder. The rest is flat or poor. This reef is inconsistent, and it’s showin’ its true colors.

Signing off, Rusty.

Information about the Slade Bay/Boot Reef Surf forecast

A general guide to surfing at Slade Bay/Boot Reef can be found by selecting the local surf guide option on the grey menu.

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 Slade Bay/Boot Reef 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.
