The Lowdown

Alright, Rusty here, looking at the upcoming swell window for Periscope Point. This is a tricky little reef setup, sheltered from the south, and it's inconsistent, so we need to be patient. But when it lines up, it can be a gem.

First things first, we’ve got a bit of a slow start. The first few days are there, but the conditions are just *marginal* with a lot of cross-off wind. The swell is hanging around the 4ft to 5ft range from the SW, with a decent period of 14 to 15 seconds. The energy is moderate (around 1155). It's surfable, but it's not the kind of thing that gets me out of bed early. The water temp is about average for this time of year.

Now, hang on to your boardies, because Monday the 20th of July is the real standout. The afternoon session is looking excellent for experienced surfers. We're seeing a solid 7ft swell from the SW, with a period of 16 seconds. That's a proper groundswell with a lot of punch, and the energy is strong (2373). The winds are a light cross-off from the SSE, keeping the face clean. The only thing to keep in mind is that this is a reef break, and it's inconsistent, so the sets will be spaced out but powerful. Because it's a reef, that long period will wrap in nicely. You'll likely have the place to yourself crowd-wise, but if it doesn't, it can get a bit full.

The following Tuesday the 21st of July morning still has some size (6ft) but the energy drops a bit (1523). It's another option for the bold, but the Monday afternoon is the one to chase.

After that, the swell fades through the rest of the week, dropping back to the 3ft to 4ft range. The winds stay cross-off, but the energy is lower. Nothing to get too excited about, but there are still some clean enough waves for a longboard if you're desperate.

The last week of July and into the 30th and 31st sees a bit of a pulse coming back. Thursday the 30th of July has a very clean morning with 4ft swell and a long 19 second period, but the energy is still moderate (1334). Then Friday the 31st of July morning shows a spike back up to 6ft from the SW with a 17 second period and strong energy (2188). That's a promising long-range call, but it's a fair way out, so don't book the time off just yet. The wind is a moderate cross-off, so it could be a great end to the month.

In short, circle Monday the 20th of July afternoon. That's your best bet. Everything else is a waiting game or a gamble on the last day of the month.

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.
