Alright folks, Rusty here with the long-range outlook for Periscope Point.

We’ve got a solid run of action ahead, kicking off on Thursday July 9th and rolling through to the end of the month. The first few days are the real standout, but there's a bit of a lull to work around later on.

Thursday July 9th brings in the first pulse. We're looking at a strong groundswell from the SSW, running 6ft at a very long 15 seconds. The combined energy is pumping at 1714, so the ocean will have plenty of push. Winds are light cross-off from the SSE, which is a real bonus – it’ll keep the faces clean. This is a proper reef break, advanced-only territory, and with that much period, the sets will be lined up and powerful. The water temp is sitting at 82°, which is about 2° warmer than average, so it's a touch on the balmy side for mid-July. Get on it – this is the pick of the week.

Friday July 10th holds in with similar energy, though the mornings are a little more marginal with tide considerations. The afternoon sees the swell bumping up to 6ft from the SW at 16 seconds and energy at 1852, but the quality reports suggest it might be a bit tricky. Saturday July 11th still has decent 5ft to 5ft SSW swell with a 15-second period, and the same light cross-off wind. It won't be as clean as Thursday, but still a good window.

Sunday July 12th sees the swell drop off significantly to around the 4ft mark, and wave energy takes a nosedive too. The next real highlight comes on Tuesday July 14th. The afternoon session looks excellent for advanced surfers – the swell jumps to 6ft from the SSW with a long 18-second period, and the energy number is a massive 2544. Light cross-off winds again. That is a serious, powerful groundswell headed into the reef. This is another proper standout session, but remember: that kind of period and size at a reef spot is purely for the experienced crew.

Wednesday July 15th has some size (7ft morning, 6ft afternoon) but the wind picks up to a moderate 12 mph cross-off, which will still be clean but less perfect. The energy remains high.

We hit a bit of a flat spot from the 17th to the 19th – mornings in particular are pretty weak, with swell dropping into the 5ft range and lower energy. It’s not terrible, but it’s not worth writing home about.

Then we get another interesting window around Thursday July 23rd. Swell comes back up to 5ft from the SSW at 18 seconds, with very light cross-off winds of only 6 mph. The energy is back up to 1460 for the afternoon. That late-July groundswell looks promising, though being so far out, you gotta keep an eye on it. Friday July 24th also looks tidy, with consistent 5ft to 6ft SSW swell, low winds, and good energy.

Overall, the first week is firing with two clear standout days – Thursday the 9th and Tuesday the 14th. The second week has some interesting juice but is a bit more inconsistent and a lot less certain. This break is an inconsistent, sheltered reef, so when it works it really works, but it can be quiet for days. The crowds here are only "sometimes," so if the swell lines up, you might just score a peak to yourself.

Stay salty,
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.
