Right, folks, Rusty here. Let’s have a look at what’s cookin’ at Slade Bay/Boot Reef (reef). It’s a pretty quiet picture for the next couple of weeks, so don’t be expectin’ any fireworks just yet.

We start off on Sunday the 12th with a tiny 0.3ft SW groundswell, period a very long 16 seconds. The water is a toasty 68°, which is a massive 8° above normal – that’s seriously unusual, feels like a warm bath out there. But the energy is weak (30), and that’s all we’ve got. The whole first week is a write-off, honestly. Through Monday the 13th, Tuesday the 14th, Wednesday the 15th, Thursday the 16th, Friday the 17th, and Saturday the 18th, we’re lookin’ at flat nothingness – swell heights barely ticklin’ 0.3ft to 1ft, with poor surf conditions. There’s a glassy moment on Tuesday afternoon and Wednesday afternoon, but not enough swell to push a leaf. That’s a solid 7 days of no-go.

The second week doesn’t get much better. Sunday the 19th through Wednesday the 22nd, it’s still tiny, mostly 0.3ft to 1.0ft, with a few 3ft to 3ft pulses on the 21st and 22nd. The energy on the 22nd hits 64 and 61 in the morning and afternoon, but that’s still weak. Winds are messy, mostly cross or cross-off, so don’t get your hopes up.

Now, Thursday the 23rd morning, we finally see a little flicker. A 3ft W swell with a short 6-second period, offshore N wind, clean. The energy is 90 (weak) and the comment says “surfable waves but very ordinary conditions.” It’s a score of 1 – nothin’ to write home about, but it’s the first real possibility. That’s the only half-decent window in the near term, but it’s still a shadow of what this reef can do.

The real story, and the only standout in this whole 16-day run, is on Monday the 27th of July. That’s a long way out, so take it with a pinch of salt, but the numbers are eye-waterin’. We’ve got a 10ft WSW swell, period 9 seconds, with the combined energy at a massive 2358 – that’s very strong. The morning is glassy, dead calm, with ENE wind at 0 mph. The break is a reef, so that long period groundswell will be lined up nicely. The comment says “excellent surf conditions for experienced surfers,” and a score of 4. That’s the one to circle on your calendar. It’s a bit of a beast, over 8ft, so this is strictly for the crew who know what they’re doin’. The afternoon sees the size drop to 8ft but the wind goes cross, so the morning is the window.

Monday the 27th morning – that’s your best bet. Everything else is a flat, wind-affected mess until then. You’ll be waitin’ a long time, but that one session looks like it’ll be worth the patience.

Rusty.

Information about the Slade Bay/Boot Reef Surf forecast

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