The Lowdown

Alright folks, Rusty here. Let’s get into what’s coming up for Supertubos.

Right now, things are pretty flat and there’s a long, frustrating wait on the cards. From Tuesday the 11th right through to Wednesday the 19th, we’re looking at a real doldrums stretch. The swell is tiny—like, ankle-snapping 1 foot at best—and the wind is mostly a cross-off breeze, which isn’t helping the sets that aren’t there. The wave energy is weak, barely ticking over. It’s a full eight days of pretty much nothing for a surfer to get excited about. You’d be better off waxing your board at home.

Then we get a brief tease on Thursday morning, the 20th of August. The swell bumps up to a modest 2 feet from the NW with a period of 10 seconds. The real story that morning is the wind: it’s glassy. Dead calm. That kind of clean surface is rare and very welcome, so if you’ve got a longboard and a lot of patience, you might find a few crumbly lines. But the combined energy is still low (99), so don’t expect much push. It’s surfable, but ordinary.

After that, it’s back into the doldrums through the 21st to the 23rd, with even smaller swell and fresh winds kicking up. Pretty grim.

Now, here’s where things get interesting. The standout window opens up on Monday the 24th of August. This is the one to circle on the calendar. We’ve got a solid 7 to 8 foot swell rolling in from the NW. The period is short at 8 seconds, so it’s more of a windswell than a proper groundswell, but the combined energy is strong (602 in the morning, 708 in the afternoon), so there’s plenty of power behind it. It’s a beach and reef set-up here at Supertubos, and with that NW direction it should line up well.

The morning looks cleaner with a light N breeze (cross-off), so you’ll get some decent, hollow wedges. That’s the pick of the day. The afternoon gets a bit more of a cross-shore wind, which might mess with the shape. This is heavy wave territory though—over 6 feet, so it’s strictly for the experienced crew. Beginners, stay on the sand. The water temp is about average for this time of year.

Tuesday the 25th drops right back off to tiny surf, so that Monday window is your only real shot at something with some punch during this forecast. Long-range call, so keep an eye on it, but if it holds, that Monday morning at Supertubos looks like the best we’ve got.

Stay stoked,
Rusty

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.
