The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Tubes over the next couple of weeks.
It’s a mixed bag, for sure. We’ve got plenty of swell on the charts, but the beginning is a total mess. From Friday the 4th through Sunday the 6th, the wind is blowing strong onshore, trashing what could’ve been decent size. There’s a 10ft swell on Friday morning (SSE) but with 19 mph cross-shore wind, it’s just lumpy junk. The combined energy reads 2137 (moderate), but it doesn’t matter with that chop. You’d be better off doing something else. That same story of onshore wind and blown-out surf runs through the weekend.
Monday the 7th and Tuesday the 8th start to clean up as the wind lays down. Monday morning sees a clean 7ft SSW swell with a light offshore breeze from the NE. It’s still considered marginal, but it’s a big step up. Tuesday morning the 8th is the first true clean window – a 4ft SW groundswell with glassy cross-offshore wind out of the SSE at just 3 mph. It’s small, but it’ll be clean.
The real highlight, the one you don’t miss, is Friday morning the 11th at Tubes. You’ve got an excellent 8ft SW groundswell with a 14-second period, and a clean, light offshore wind from the SW at 6 mph. The combined energy is 2120 (moderate), and the swell direction is dead-on the optimum. This is a proper reef point setup – powerful, long-period, clean lines for experienced surfers. That is your morning.
Saturday the 12th morning stays in the game with a solid 10ft SW swell and light offshore wind, but that’s pushing into expert-only size. Tuesday the 15th afternoon has a clean 8ft WSW swell, but the period is a short 6 seconds, so it won’t have a lot of punch. Later on, the huge 16ft to 20ft swells on the 16th and 18th are there, but the wind or period knocks them out of top contention.
So, in plain speak: the start is rough, a small clean day on Tuesday, but lock in Friday the 11th. That’s your best bet by a long shot.

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