Alright, let’s break down what’s cookin’ at Periscope Point. This is a sheltered reef, advanced only, and it’s inconsistent, so you gotta be picky. The first couple days are a write-off – the 4th has 1.6m from the SSW with a 15-second period and 1129 combined energy, but the wind is cross-off and the conditions are marginal with questionable tide. Don’t waste your time.

First real highlight is Sunday morning the 5th. Swell holds at 1.6m from the SSW, still 15 seconds, energy jumps to 1482, and it’s clean with a light ESE cross-off breeze. The guidance says expect very good surf, and with that long period and direction lining up with the optimum S swell, it should be a gem. Crowds are only *sometimes* an issue, so you might get it quiet. That’s the standout of the early stretch.

Monday the 6th drops to 1.2m but the period stretches to 17 seconds – proper groundswell. Energy is 1308, but it’s still marginal with tide. Tuesday the 7th afternoon is worth a look: 1.4m from the SW, 16 seconds, energy 1025, clean with a light SSE cross-off. The guidance calls it “expect very good surf conditions.” Solid.

Then Wednesday the 8th afternoon is the big one for the experienced crew. 2.2m from the SW, 15-second period, and a massive 2174 combined energy – that’s strong wave energy. Wind is a light SSE cross-off at 10 km/h, glassy. The file says “excellent surf conditions for experienced surfers.” This is your best window, no question. But at 2.2m, it’s over 2.5m on the sets, so experts only.

After that, the swell backs off into the second week. Thursday the 9th afternoon has 1.9m from the SSW, 15 seconds, energy 1605, and “expect very good surf conditions.” Friday the 10th morning is similar at 1.7m, 15 seconds, 1532 energy. Clean again. The 11th afternoon drops to 1.5m, 14 seconds, 891 energy, still clean with a light breeze.

The second week settles into a smaller, more consistent pattern. From the 12th to the 16th, you’re looking at 1.0m to 1.4m swells, mostly from the SW, periods between 12 and 18 seconds, and cross-off winds keeping it clean. The standout there is Tuesday the 14th morning: 1.4m from the SSW, a very long 18-second period, and 1230 energy. That’s a classic groundswell – will wrap nicely around the reef but might be a bit straight for beach breaks.

The 18th afternoon picks up again: 1.4m from the SW, 16 seconds, 1012 energy, with “expect very good surf conditions.” And Sunday the 19th morning has 1.6m from the SW, 16 seconds, 1391 energy, light SSE cross-off. A solid finish.

Best of the whole run is Wednesday the 8th afternoon – that 2.2m SW swell with clean light winds and expert-only power. If that’s too heavy, go for Sunday the 5th morning or Tuesday the 7th afternoon.

Rusty.

Information about the Periscope Point Surf forecast

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