The Lowdown
Alright, surfers, Rusty here. We've got a solid window of surf on the way, starting this Thursday the 13th, but you've gotta be smart about it. The ocean is absolutely loaded with energy, but that energy is going to be too much for most spots for a few days. The water temp is sitting at about average for this time of year, 61°F, so nothing out of the ordinary there.
The standout session for the entire run is going to be Friday the 14th in the morning at Twilight Beach. We’re looking at a serious 10ft SSW groundswell, with a long 16-second period, and a light NE breeze that's coming across-offshore. That combo is going to produce some clean, powerful, and perfectly shaped waves. This is strictly for experienced surfers though – that's a lot of water moving around with a combined energy of 5076, and it's not a beginner-friendly day.
Things ease off a touch into Saturday the 15th morning. The swell drops to a still-chunky 7ft from the SSW, with a 14-second period. The wind swings NNE and goes offshore, making for another clean morning session. The energy is still strong at 1874, so it’s another one for the crew who know what they're doing.
We hit a bit of a lull in quality for a few days. Sunday the 16th and Monday the 17th have size, but the wind’s a bit messier, making things marginal. By Tuesday the 18th, a strong WSW wind (25 mph) is going to trash the surface completely, turning it into a washing machine. That day is a write-off for paddling – if you’ve got a kite, it might be interesting, but for a surfboard, forget it.
Wednesday the 19th and early Thursday the 20th are still messy, but then Thursday afternoon looks magic. The wind goes glassy, dropping to a mere 3 mph from the SSW, with a 8ft SW swell. That will be clean as a whistle with a combined energy of 2747. Another one for the experienced crew.
Friday the 21st sees the swell pump back up to a huge 11ft from the SW. The energy is immense at 5387, but the morning wind is onshore and messy, and the afternoon is the same. It's just too big and won't have any shape for most.
The second week starts to look promising again. Saturday the 22nd morning has a 10ft SSW swell with a light NNW cross-off breeze, which is clean and excellent for experts. Then we have a few days of mixed conditions, but the real highlight for this part of the run looks to be Thursday the 27th in the morning. A strong 8ft SSW swell with a very long 16-second period, and a cross-off NNW breeze. The energy is pumping at 6182, and the conditions look clean. That’s a solid session for the experienced surfers out there. The rest of the days after that are a bit of a mix of size and chop, nothing that jumps out as a must-surf.
Stay safe out there. This is a period for the experienced crew to get their fill.

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