The Lowdown
Right, let’s have a look at what’s on offer for The Peak over the next couple of weeks.
First up, we’ve got a bit of a slow start. The early part of the window is pretty disappointing, to be honest. Saturday the 5th kicks off with some waist to chest high swell from the west, around 6ft, with a 10-second period, and the wind is cross. It’s a bit of a messy start, and the energy is moderate (644). The afternoon cleans up a little, dropping to 4ft with a cross-off breeze, but it’s not really singing. The weekend and start of the week are a write-off – Sunday the 6th is tiny, and Monday the 7th sees a jump in size but the wind is howling onshore, making it a total mess. Tuesday the 8th is not for the faint-hearted: 13ft of westerly swell with a 12-second period, but the wind is a strong cross-onshore. That’s a lot of water moving, but it’s going to be a lumpy, blown-out beast. The energy is very strong (4433), but only for the hardcore. The rest of that week is a mix of onshore winds and choppy conditions, with nothing really coming together.
Now, here’s the good news. The real standout window is the weekend of the 12th and 13th of September. Saturday the 12th is looking like the best bet by a long way. The morning has a solid 6ft swell from the west-northwest, 11-second period, and the wind is a light offshore from the east. That’s clean, lined-up groundswell, and the energy is moderate (730). The afternoon is even better: clear skies, an offshore breeze from the east-southeast, and 5ft of swell. This is where you want to be – it’s going to be glassy, with some proper shaped waves rolling in. The Peak is a reef break, so it handles that west-northwest swell perfectly. Crowds are a possibility, but for waves this good, it’s worth it.
Sunday the 13th is a bit smaller, with 3ft of swell and glassy conditions in the morning. It’s still a fun, clean wave, but the size drops off. After that, the following week looks pretty average again, with a lot of onshore flow and smaller, weaker swell. There’s a tiny window on the 17th where the morning has 5ft of swell and clean cross-off wind, but it’s not a standout.
Overall, the best surfing is on Saturday the 12th. The swell is solid, the wind is perfect, and the energy is there. Get on it.

Information about the The Peak Surf forecast
The above surf forecast table for The Peak provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Peak can be found by selecting the local surf guide option on the grey menu. Our The Peak 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 (The Peak) 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 The Peak 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.
