Alright, Rusty here, let’s talk about what’s on the menu for Periscope Point over the next couple weeks.

First up, we’ve got a reef setup that’s sheltered and likes south in the swell window, so it needs the right angle to really fire. Right now, the water’s sitting around 81°, which is a touch warmer than usual for this time of year—nothing crazy, just a little noticeable.

It’s a bit of a slow start. We’ll see some semi-clean cross-off swell filtering in on Sunday afternoon, 12 July, but it’s inconsistent and only pushing around 3ft from the SW with a 13-second period—not worth rushing out for. The combined energy is only 483.

Monday 13 July drops off even more—3ft and 2ft—and the wind picks up a bit, so I’d say skip it.

The first real standout arrives Tuesday 14 July. The swell builds to 6ft–6ft on Tuesday morning and afternoon from the SSW, period stretching out to 18 seconds. That’s proper groundswell, and for a point like this, long-period south swells wrap in beautifully. Wednesday 15 July holds 6ft–7ft, also SSW, with decent 16–17 second periods and clean surfaces from that SE cross-off breeze. These days are the pick of the first week—the energy climbs into the 1800s–2200s, and while the ratings are modest, the conditions are clean and the waves have shape.

Thursday 16 to Saturday 18 July settle back a bit—4ft–5ft, still SW/SWW, still clean enough, but smaller and less punchy.

Now here’s the big one for the second week: Monday 20 July afternoon, we’ve got a 8ft SSW swell with a 17-second period and light cross-off wind. The combined energy hits 3024—that’s strong, serious water moving. This is for experienced surfers only. If you know your way around a reef and can handle that size and power, this is the session to aim for. It’s a long way out, so keep an eye on it, but the signs look good.

That heavy SSW swell continues into Tuesday 21 July morning at 7ft, but by afternoon it gets a bit cross-choppy.

Another excellent window opens up Saturday 25 July and Sunday 26 July. Saturday delivers 6ft–6ft SSW groundswell with periods of 18–19 seconds, clean cross-off wind, and energy readings in the 2500s. Sunday morning holds 7ft from the SSW, still clean, still solid. After that, it fades through the final days.

Crowds can show up here sometimes, so if you’re heading out on those standout days, expect company.

All in all, the two true standouts are Tuesday 14 July / Wednesday 15 July for the first week, and the Monday 20 July afternoon session for the second. The 25–26 July weekend also looks like a cracker.

So grab a board you trust and pick your window. This reef has some real grunt coming.

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.
