The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for T-Street over the next couple of weeks.
We’ve got a real mixed bag ahead. The first week or so is plagued by a constant cross-onshore wind, which is gonna make the waves bumpy and hard to read. The water is a super warm 75°, that’s a whopping 7° warmer than normal for this time of year, so it’s like bathwater out there, but the surf quality is the real letdown. The early reports are all “marginal” or “poor,” not what we want to hear.
The first few days – from Saturday the 29th of August through the following Friday – are all in the 2 ft to 4 ft range from the SSW. The swell period is long (14 to 17 seconds), which is classic groundswell, but the wind is just a buzzkill. The combined wave energy is moderate, but it’s wasted energy with that constant cross-onshore breeze.
We get a bit of a pulse on Monday the 7th of September. The swell bumps up to 5 ft to 6 ft from the S, with strong energy. The period is still a solid 14 seconds, so there’s some push, but it’s still cross-onshore. That’s frustrating.
Now, the real standout – and I mean *the* standout in this whole run – is the morning of Sunday the 13th of September. The swell is a modest 3 ft from the SSW, but check this out: glassy conditions. A light NNE wind of just 3 mph. The forecast says “expect good surf conditions.” For a spot like T-Street, a glassy morning with a long-period 12-second SSW groundswell is about as good as it gets. This is the window to be in the water. Keep in mind, though, we’re talking more than a week away, so it’s a promising call but not a guarantee.
Before that, the swell actually gets quite big. By Tuesday the 8th of September, we’re looking at 8 ft to 12 ft from the SSW. That’s big, powerful stuff – the energy is very strong. This is expert territory only. Beginners should stay well clear. And with a cross-onshore wind, it’s going to be a messy, challenging beast, not the clean, grinding lines you’d hope for.
The last few days peter out into small, weak swell (2 ft to 3 ft) with mostly cross-onshore winds. There’s a gap of poor surf from the 10th to the 12th of September before that glassy Sunday morning. After that Sunday morning window, the wind swings back onshore in the afternoon and it’s game over.
So, if you’re surfing T-Street, the call is simple: hold out for the glassy morning of Sunday the 13th of September. That’s your one true standout. The rest is a grind of onshore wind and marginal conditions.
Rusty.

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