The Lowdown

G’day, I’m Rusty. Let’s break down what’s cooking at Tramandai for the next couple of weeks. It’s a bit of a mixed bag, with some real promise if you’re patient, but also plenty of days where you’re better off doing something else. The first few days are pretty ordinary, so don’t get your hopes up too early.

The surf kicks off Monday the 20th of July, but honestly, it’s not much to write home about. We’ve got a 5ft ENE swell pushing in, but it’s got a short period of 9 seconds and a cross-shore NNE breeze at 9 mph. The combined energy is moderate at 381 and the water’s sitting at 60°, which is a bit colder than normal for this time of year. It’s a marginal call with questionable tide, so I’d give it a miss.

Tuesday the 21st is even smaller, with 4ft ENE swell and a period dropping to 8 seconds. Winds are light from the NNE in the morning, then go cross-on in the arvo. Still marginal. Wednesday the 22nd morning actually looks a bit cleaner with a light WSW cross-off breeze and 4ft swell, but it’s still small. The afternoon gets a stronger W wind at 12 mph, which keeps it clean but bumpy.

Now, Thursday the 23rd sees a bit more size – 6ft SSE swell – but the wind is cross-on from the SSE at 9 mph, making it choppy. The energy is moderate at 546. By the arvo it’s onshore and messy. Not worth it.

Friday the 24th is a write-off. Strong ENE winds at 16 mph, onshore, with poor conditions all day. Saturday the 25th morning is still messy with a cross-shore NNE breeze, but the arvo! Saturday afternoon the 25th of July, the wind swings to a light offshore WNW at 9 mph, and the swell drops to 4ft from the ESE. It’s clean and offshore, with moderate energy at 434. This is a solid option for a session – nothing huge, but it’ll be fun and clean.

Sunday the 26th of July is the real standout. Morning has a 5ft E swell with a 9-second period, cross-offshore W wind at 9 mph, and energy at 553 – moderate but solid. It’s clean. Then the arvo goes glassy with a SSW breeze at 3 mph, and the swell holds at 5ft from the E. That’s the best on offer in the whole outlook. Glassy, clean, and a decent pulse of groundswell. Perfect for a long session.

Monday the 27th and Tuesday the 28th are a step back – smaller, cross-shore winds, and poor conditions. The energy drops off. Wednesday the 29th is tiny, with 2ft swell and weak energy at 83, but it’s clean with a light offshore NW wind. Surfable but very ordinary.

Thursday the 30th has a bit more oomph, with 4ft SE swell in the morning and a clean cross-offshore WSW breeze, but the period is short at 6 seconds. The arvo picks up a 4ft ENE swell, but it’s cross-shore and messy.

Friday the 31st of July is a no-go. Strong NE winds at 16 mph in the morning, rising to 22 mph in the arvo, with an 8ft ENE swell that’s onshore and lumpy. Energy hits 717 – moderate to strong – but it’s pure chop. Only for kites, not for paddle surfing.

Saturday the 1st of August is still messy with cross-shore winds and a 7ft ENE swell. Sunday the 2nd is similar – cross-onshore, choppy. Monday the 3rd is more of the same.

Then Tuesday the 4th of August brings a glimmer of hope. Morning has a 4ft ENE swell with a light cross-offshore NNW wind at 6 mph, and it’s clean. Energy is weak at 204, but the conditions are good. It’s a small, clean session to wrap things up.

In short, the standout is Sunday the 26th of July. That glassy arvo with 5ft E swell and no wind is the one to circle. Saturday afternoon the 25th is also a solid pick with offshore winds. Everything else is a grind or a wait.

Rusty.

Information about the Tramandai Surf forecast

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