The Lowdown
Alright, grab your wettie, because it's looking pretty bleak out there for a while. I'm not gonna sugarcoat it. We've got a stretch of nothing but small, weak surf on the cards for the next week and a half. It's the kind of lineup that'll have you checking your board for dings just to have something to do.
The water temp here at Supertubos is sitting at 65°, which is a solid 4° colder than usual for this time of year. That's a bit of a shock to the system, so don't be fooled by the sun; you'll want the thicker rubber.
Right now, and for the next few days, it’s flat and pretty frustrating. Thursday the 10th and Friday the 11th are offering nothing but knee-high slop, with 0.7ft to 1ft of swell and a weak period around 7 seconds. The wind is a steady cross-offshore breeze, which keeps the surface clean, but there's just zero push to it. It’s the kind of day you paddle out, sit for ten minutes, and think about your life choices.
The weekend doesn't offer much of a change, honestly. Saturday the 12th has a little pulse, up to 2ft, but it’s still short-period stuff. Sunday the 13th afternoon sees a bit more size, jumping to 4ft from the WNW with a longer 12 second period, and the energy finally ticks up into the moderate range (474). But the wind swings onshore, and it’s just a mess. It’s not surfable, it’s just messy.
We got a long stretch of nothing from the 14th through the 22nd. There's a few pulses of waist-high waves, like on Monday the 14th and Sunday the 20th, but they are all short-lived and still lacking any real power or consistency. The wind stays mostly offshore, which is a blessing, but the ocean is just… empty. It's a flat spell, plain and simple. The weak energy readings, with values in the single and double digits, confirm it. There's nothing to get excited about.
There is a little blip on the 23rd of September, but it’s not worth planning a session around. It's still small and wonky. The whole period is a write-off for any decent paddle surfing. For the most part, we have a blank run, which happens here. But with this many days of clean, offshore winds, if you really have an itch to scratch, the setup looks far more interesting for a kite surfer than for a surfer. The wind is there, even if the waves aren't.
Keep the board in the car, but be prepared to stay dry. Forecasts can change, and this stretch of northerly wind is building up a lot of hope for later in the month. But for now, I wouldn't hold my breath.

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