The Lowdown
G’day, Rusty here. Let’s take a look at what’s on the cards over the next couple of weeks. It’s a slow start, but there’s a proper pulse building further out, so keep the faith.
We get things rolling on Sunday the 16th with some leftover southwest groundswell. Waves are around 4ft with a long 15-second period. The morning session is clean with a light cross-offshore breeze, and the water is a touch warmer than usual for this time of year, about 88°. The ocean’s got a bit of push to it, with combined energy in the moderate range. The afternoon’s a write-off with the onshore wind, so get in early.
Monday the 17th is much the same story—clean in the morning, but the swell drops a notch. Tuesday the 18th is the pick of the early week. The morning is glassy, with waves holding at 4ft and that long 14-second period pushing through. The energy is still moderate, but it’s clean and workable. That’s your window. Afternoons are all choppy and junk.
The swell fades through the middle of the week. Wednesday and Thursday the 19th and 20th see wave heights drop to around 3ft and then 3ft. The mornings stay clean, but the size just isn’t there.
Friday the 21st and into the weekend we hit a proper lull. Waves are down in the 2ft range. There are some glassy mornings, but honestly, it’s log territory unless you’re just keen for a paddle. The energy is weak.
Now, for the good stuff. We’ve got a long-period pulse arriving around Sunday the 23rd. Wave heights are small, but the period jumps to 18 seconds—that’s proper groundswell. The energy bumps back up. It’s a sign of things to come, but the size is still a bit small to get excited about.
The standout day is Saturday the 29th of August. We’re looking at 5ft of southwest swell with a 16-second period, and the combined energy is strong. It’s glassy, dead calm, and pushing well overhead. That’s the one. It’s the best session of the whole window. The Sunday after is still okay, but the wind gets a bit messy.
So, the plan: don’t stress about the small stuff this week. The 18th is fine for a quickie. But the 29th is the one you want to be free for. It’s a long-range call, so treat it as promising rather than locked in, but the signs are looking very good. Mornings are your friend; the afternoons are a no-go.
Rusty.

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