The Lowdown

Rusty here,

Alright, let's talk about the 16-day window. Got a bit of a patience test to start, but there's gold at the end of the rainbow if you wait.

The Big Picture

The first few days are a total dead loss. The first surf worth your time doesn't show up until Thursday the 10th of September. That’s a 2-day gap of nothing but garbage right off the bat. Once we hit that Thursday, we get a long stretch of clean conditions, though the swell size is mostly on the small side.

Day-by-Day Breakdown

Tuesday the 8th and Wednesday the 9th of September? Forget it. It’s a mess of strong onshore wind and a big, lumpy 8ft swell. The wave energy is a very strong 2965, but it’s just a washing machine. No quality at all.

Thursday 10th September is the first day you might actually paddle out. Morning brings a clean, 5ft swell from the ENE. The period is short at 7 seconds, so don't expect much power, but the cross-offshore wind keeps the surface smooth. The combined energy is a moderate 686. A decent way to stretch the arms.

Friday 11th September keeps the cleanskin theme. The swell drops to 4ft from the ENE, but the period stretches to a much nicer 11 seconds. This gives the waves a bit more shape and punch. Energy is 631. The morning is the better session.

Saturday 12th & Sunday 13th September is when it really fades. Saturday is 2ft by the morning, and by Sunday we’re down to 2ft with energy as low as 80. The wind is clean, but you’ll be sitting there waiting a long time for a rideable lump.

Monday 14th September – The Real Deal

This is the one. Circle it. The afternoon session on Monday the 14th is the standout of the whole 16 days. The swell height is a tiny 2ft, but the period is an absolutely massive 22 seconds. That’s a deep ocean groundswell that will turn that small size into perfectly formed, powerful lines at a reef like Tennis Courts. The energy number is only 288, but for that period, it's way more potent than it reads. The wind is a light, cross-offshore breeze, so it will be glassy and clean. This is an expert-only wave due to the tricky take-off from the long period, but it's the best quality on offer.

After that, from Tuesday the 15th through to Wednesday the 23rd of September, the story is small and often windy. Swells are mostly in the 2ft to 3ft range. The wind builds again, with gusts hitting 22 mph on the 23rd, which kills any chance of a decent paddle-surf. The energy often drops below 500, making it a kite-surfing kind of setup rather than a good one for a surfboard.

One More to Watch

Keep an eye on Saturday 19th September. The morning is nothing special, but the afternoon session cleans up nicely. You get a clean 3ft swell from the SSE with a light offshore breeze from the NE. The combined energy is a quiet 472, but for a longboard in perfect conditions, it will be a fun session.

So, to end it: Thursday the 10th is the starting gun, but Monday the 14th afternoon is the one to really get excited about for quality over quantity. The rest is mostly clean, small, and forgettable.

Information about the Tennis Courts Surf forecast

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