The Lowdown
Alright, Rusty here. Let’s break down what Twilight Beach is showing for the next couple of weeks.
Water temp is sitting right around 62°F, which is pretty normal for this time of year. The whole picture is a bit of a coin flip—there are waves on most days, but wind and conditions will decide if it’s any good.
The first few days are rough. Sunday the 13th has a clear sky but a cross-shore breeze making things choppy. Swell is about 4ft from the SSW with a 14-second interval. Afternoon turns onshore, bumping the swell up to just over 5ft, but it’s messy. Not a great start.
Monday the 14th and Tuesday the 15th build size up to around 7ft and 8ft, but cross-onshore winds and lumpy conditions keep the quality low. Wednesday morning the 16th improves a bit with cross-offshore breezes and a 6ft SSW swell, but still only marginal. The real gem comes on Thursday the 17th. Both morning and afternoon have clean offshore winds from the N and NNE, light to moderate, with a tidy 4ft SSW swell at 15 seconds. That’s clean, rideable, and the best bet of the first week.
Friday the 18th holds clean in the morning with a 4ft SSW swell, but the afternoon turns ugly with cross-onshore wind and chop. Saturday the 19th is a total loss with near gale-force winds and rain. Sunday the 20th jumps up to 8ft but is lumpy again.
Now for the second week, Monday the 21st is the big one. Morning offshore winds from the NNW with a solid 8ft SSW groundswell at 15 seconds. Clean and powerful – this is the standout session for experienced surfers. The afternoon gets bumpy, but the morning window is prime.
Tuesday the 22nd holds size at 8ft with a long 16-second period, but light cross-onshore and then onshore winds spoil it. Wednesday the 23rd is similar. Thursday the 24th morning cleans up nicely with cross-offshore breezes and an 8ft SSW swell at 16 seconds – a good option for confident surfers. Friday the 25th morning is another winner: offshore NNE winds, clean, with a 7ft SSW swell at 15 seconds. Weekend of the 26th and 27th is blown out with strong winds, and Monday the 28th stays poor.
So, if you’re looking for the best: Thursday the 17th is a solid session. But the real standout is Monday the 21st morning – mark it down. After that, Thursday the 24th and Friday the 25th mornings are good backup. Crowds are listed as *sometimes*, so you might run into a few others, but it’s worth it when the conditions line up.
Stay sharp, and I’ll see you in the lineup.

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.
