Alright, Rusty here. Let’s take a look at what’s happening at Periscope Point.

Water temperature is about normal for this time of year, nothing to write home about. This is a sheltered reef break that really fires when the swell comes from the south, and that’s exactly what we’re seeing.

We kick off on Tuesday, July 7th. The morning is a bit iffy with tide issues, but the afternoon is the real deal. We’ve got 5ft of SSW groundswell with a long 16-second period and light, clean cross-off winds. The wave energy is cooking (1018). This is the standout session in the first week, no question about it. It’s an advanced wave, so it’s not for the faint of heart, but for the crew that can handle it, this is magic.

Moving into Wednesday the 8th, the swell pushes up. The afternoon brings 7ft of SW swell, still with that long-period groundswell feel. Winds stay clean and cross-off. The energy is cranking (1967). This is getting into big-wave territory, for experts only.

Thursday the 9th holds similar size, around 6ft to 7ft, with the same steady S/SSW direction and light winds. Friday the 10th eases a little to 5ft in the morning, building back to 6ft in the afternoon.

Saturday the 11th and Sunday the 12th see the swell back off, dropping to 4ft and then 3ft by Sunday afternoon. Still clean, still fun, just smaller.

There’s a bit of a quiet spell on Monday the 13th and Tuesday morning the 14th, but Tuesday afternoon the 14th fires right back up with 5ft of long-period SSW swell (18-second period) and excellent conditions expected. Energy is strong at 1720.

Wednesday the 15th is another beauty with 6ft of SSW swell and light winds in the afternoon. The pattern holds through Thursday the 16th, with 5ft and clean conditions.

Through the second week, from Friday the 17th onward, we get a steady stream of SW groundswell, mostly in the 4ft to 5ft range. Conditions stay clean. There’s another good push on Sunday the 19th with 6ft SW swell and light afternoon winds (1419 energy). That one looks promising.

Tuesday the 21st brings a little longer-period pulse, with 3ft of SSW swell and a 17-second period. Wednesday the 22nd finishes things off with 5ft of SSW.

For a spot that’s usually inconsistent, this is a surprisingly consistent run. If I have to pick the absolute best, it’s Tuesday the 7th afternoon for that first clean, powerful groundswell, and Wednesday the 15th afternoon or Sunday the 19th afternoon for the bigger, more powerful sets. It’s an advanced reef, so know your limits.

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.
