The Lowdown
Alright, Rusty here again. Let’s look at the same run for Twilight Beach but in feet.
We’ve got a solid stretch of surf coming, but the opening days are rowdy as hell. Starting Tuesday, August 11th, a massive 18ft SSW groundswell is pouring in with a 16-second period, and the energy is thumping at 26811. Water temp is a normal 62°. But that swell is way too big for this break, and with a 35 km/h cross-onshore wind, it’s going to be lumpy and ugly. This is for absolute hardcore crew only, and honestly, it looks better for kite-surfing than paddle surfing. Afternoon drops to 15ft but still messy.
Wednesday August 12 is still oversized at 13ft with a 16-second period, cross-shore wind, and no good. Thursday August 13 stands at 12ft with a 17-second period, and while the afternoon wind turns light onshore, it’s still too big for comfort.
Friday August 14 morning is where it starts to turn. A 10ft SSW groundswell with a 16-second period, light cross-offshore wind from the NE, and clean conditions. Wave energy is strong at 5140. This is the first real window for experienced surfers. Afternoon gets choppy again.
Saturday August 15 drops to 7ft SSW swell with a 14-second period, clean in the morning with a moderate cross-offshore breeze. Afternoon gets cross-onshore and choppy.
The absolute standout is Sunday August 16. Morning brings a 4ft SW swell with a 13-second period, and killer offshore wind from the NNE at 20 km/h. Wave energy is moderate at 752. Clean, glassy lines – this is the best session for intermediates. Afternoon gets a little bumpy with a 6ft SSW swell.
Monday August 17 offers 5ft SSW groundswell with a 19-second period – very long period, meaning long, slow sets. Morning has a fresh 30 km/h offshore wind, so it’s clean but punchy. Afternoon is lighter and cross-offshore with 6ft SSW swell – excellent for experienced surfers.
Tuesday August 18 keeps it fun: 7ft SSW swell with a 16-second period, light cross-offshore winds, and clean.
Wednesday August 19: 6ft SW swell with a 16-second period, clean morning, light cross-onshore in the afternoon.
Thursday August 20 morning is a gem: 8ft SW swell with a 17-second period, light offshore wind, and clean. Wave energy is 3377. Another top pick for experienced surfers.
Friday August 21: 6ft SSW swell in the morning, but the afternoon is the winner – 4ft SSW swell, 14-second period, light offshore wind, and clean. Perfect for intermediates.
The second week gets smaller and mixed. Saturday August 22 and Sunday August 23 are poor with onshore or strong winds. Monday August 24 is a write-off. Tuesday August 25 throws another massive 12ft SW groundswell – too big again. The rest is marginal.
Best bets: Sunday August 16 morning and Friday August 21 afternoon for clean, friendly surf. For the experienced, Thursday August 20 morning is a ripper.
Rusty.

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.
