The Lowdown

Alright, Rusty here. Let's talk about Periscope Point. It's a sheltered reef break that's real picky, needing a southerly swell to fire, and it's inconsistent, so you gotta be patient. Water temp is sitting pretty at 80°F, which is just about normal for this time of year.

We've got a bit of a dry spell first. The surf worth mentioning starts on Sunday morning, August 30th. We're looking at a 5ft SW swell with a 13-second period. The energy is moderate, and with a light cross-off breeze at 6 mph from the SE, it'll be clean. Nothing huge, but it's a start.

Monday, August 31st, the swell drops to 4ft, but the period stretches out to 19 seconds. That's a long period groundswell, and the energy jumps up. It's clean, but the quality's a bit touchy with the tide. The afternoon bumps up to 5ft, but it's still marginal.

For the experienced surfer, your first real window opens Tuesday, September 1st. The morning is a bit raw at 7ft with a moderate breeze, but the afternoon cleans right up. Swell drops to 6ft from the SW, period at 16 seconds, and the energy is strong. The wind is a light, clean cross-off. That's the call.

The pattern repeats Wednesday the 2nd and Thursday the 3rd, with the swell holding around 6ft to 7ft, and clean afternoons. The energy stays in the strong range. It's solid, punchy surf for the experienced crowd.

There's a quiet patch around Friday the 4th and Saturday the 5th with weaker energy. The absolute standout, the one to circle on the calendar, is Sunday, September 6th. Both morning and afternoon look excellent. We're talking 6ft of SSW swell, building to 7ft, with the period climbing from 14 to 16 seconds. The energy is strong to very strong. Wind is a glassy light cross-off at 6 mph. That's the one. Clean conditions, good power.

The following week keeps the action going. The 7th stays clean in the morning at 7ft. The 8th looks a bit tricky with cross-shore winds, but the swell size and period are still pumping, especially in the afternoon with an 8ft swell and a huge energy reading. That's a lot of juice, strictly for experts.

The 9th of September morning is another standout for the pros, with 8ft SSW swell at 16 seconds, clean cross-off wind, and a ton of energy. The 10th and 11th ease off a bit, but the 12th and 13th bring it back strong. The 13th of September morning is a beauty: 8ft SW swell, 18-second period, light cross-off, and energy through the roof. The 14th rolls through with consistent 7ft to 8ft surf and clean conditions, keeping the run going right to the end.

So, to wrap it up: Sunday, September 6th is your top pick for a clean, powerful session. Tuesday, September 1st afternoon and the morning of the 9th are also standout windows if you've got the skill. The crowds at Periscope Point can show up sometimes, so keep an eye out.

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.
