The Lowdown

Alright, grab your board. I’m looking at a sweet little reef set-up that’s about to get consistent pulses of south-west groundswell over the next couple of weeks. This is a sheltered spot, so it’s going to be clean and rideable a lot of the time. The water’s sitting at 80°F, which is bang on average for this time of year – no wetsuit needed, just boardies.

The pattern shows a solid run of surf starting Thursday, August 27th, with a long-period SW groundswell. The energy is moderate (990) on Thursday morning, with clean 3 ft waves from a 16-second period. That’s a proper groundswell, and with the cross-off wind, it’s going to be lined up nicely. The afternoon picks up with a very long 21-second period swell, but it’s a touch smaller at 3 ft, though the energy jumps to 1354. It’s a bit inconsistent here, but it’s a reef, so when it hits, it’ll be good.

Friday, August 28th, is the real standout. Morning sees 8 ft of SW groundswell at 17 seconds, with a massive energy reading of 4161. This is strong, powerful swell. The wind is light and cross-off. This is advanced territory – way too big for beginners. The afternoon holds steady at 8 ft and 16 seconds. For experienced surfers only, but it’s clean and powerful.

Saturday, August 29th, eases a touch but stays excellent. Morning still has 7 ft of SW groundswell, energy at 2057. The wind is light and cross-off. This is still a big wave for most, but the quality is top-notch. The afternoon drops to 6 ft, shifting a bit more south-southwest, still very clean.

Sunday, August 30th, the swell starts to back off with 5 ft waves from the SW, period dropping to 13 seconds. Still clean, still good, but the energy is dropping into the moderate range (900). The week ahead keeps a mix of moderate to good conditions, with a few standout days.

The morning of Tuesday, September 1st, sees a new pulse of 7 ft SW groundswell at 18 seconds, energy at 2793. That’s a strong, long-period swell. It’s labelled as marginal for tide, but the wind is clean. Wednesday, September 2nd, holds that 7 ft size, and the afternoon is a solid 4/5 with clean, powerful lines.

After a slight dip in early September, look out for Thursday, September 10th. Morning brings 7 ft of SSW groundswell, 16 seconds, and energy at 2632. The wind is light and cross-off. This is another excellent window for experienced surfers. The afternoon is 7 ft, same direction, still clean and strong.

Friday, September 11th, wraps it up with 7 ft SSW groundswell, still good, though the wind picks up a little. The whole run is a great stretch for anyone who can handle size. Remember, this break is a reef and it’s inconsistent, so you’ll have to wait for the sets, but when they come, they’ll be clean, lined up, and packing punch.

Take it easy, and paddle smart.

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.
