The Lowdown
Alright, Rusty here. Let's talk about what's heading to Tubes.
The first couple of days are not worth paddling out for. We're looking at the 6th and 7th of September, and while there's a ton of raw energy in the water, the onshore wind is just ruining everything. Saturday is poor, Sunday is marginal. Don't bother.
Things finally clean up on Tuesday the 8th of September. It's glassy in the morning, the swell drops to about 4ft, and the period is a solid 13 seconds. The combined energy is way down at 697, but it will be clean and surfable. Check the tide.
We bottom out on Wednesday the 9th, with the swell down to about 2ft, but it's glassy again in the a.m. Then Thursday the 10th gives us a proper clean-up: a 6ft SW swell, 13 seconds, and clean cross-off wind. That afternoon it bumps up to 8ft, but the wind goes cross and it gets a bit lumpy. The water temp is a chilly 62°, which is over 4° colder than normal for this time of year. That's cold.
Mark your calendar for Monday the 14th. That morning it's a clean 8ft SW swell under light offshore winds. The energy is a solid 2051. This is the best window in the whole outlook for strong, clean waves for experienced surfers. Tuesday the 15th backs it up with another clean 8ft day with a gentle offshore breeze in the afternoon.
Wednesday the 16th is a big one, too. That morning you've got a very long-period 16-second SW groundswell at 8ft under clean offshore. The energy jumps to 3219. That afternoon it gets even bigger, hitting 11-12ft with a 14-second period, still clean and offshore – but that's expert-only territory.
The second week holds onto the clean vibes, but the wind gets stronger. Thursday the 17th and Friday the 18th still have clean, ridable surf in the 5ft to 7ft range. Then on Sunday the 20th, we get a clean 10ft to 11ft swell, but with a short, choppy period of 7-8 seconds. It'll be punchy and a bit of a bumpy ride. The week finishes off with a cleaner, longer-period 5ft SW swell on Monday the 21st.
A lot of good days in there if you pick ‘em. But the real standouts are that Monday the 14th, Tuesday the 15th, and Wednesday the 16th.
Rusty.

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.
