The Lowdown
Alright, listen up. We're looking at a patchy two weeks ahead. The main show is an advanced reef called Tennis Courts. It's exposed, fairly consistent, and the water temp is about normal for this time of year.
We're starting with a solid, messy pulse. From Friday the 31st of July, the swell is 6ft to 10ft, but it's gettin' hammered by a strong breeze from the ENE. The wave energy is moderate to strong, but the wind is cross-off, making it a choppy, short-period mess. The setup looks more interesting for kite surfing than paddle surfing. For a beginner, anything over 5ft is a handful, and over 8ft it's expert-only, but with this wind, no one's having a good time.
Things clean up a little on Tuesday the 4th of August. The wind drops to a gentle breeze, the swell is 5ft with an 11-second period, and the wave energy is moderate. The Tuesday afternoon session is looking like the best of the first week, but it's still not epic.
Then it goes flat and poor from the 5th to the 9th of August. The swell drops, the period gets shorter, and the wind is up.
On Monday the 10th of August, the swell direction swings to the SSW, which is the sweet spot for this break. The swell is only 3ft, but the period is a very long 16 seconds. This is a proper groundswell, but it'll be breaking straight. The wind is cross-off, and the energy is moderate. The waves are small, but with that long period, there could be a few clean ones.
The real standout is the 14th of August. A 2ft, 19-second groundswell from the S and glassy, calm conditions. The wave energy is 490. For a reef, that's a recipe for perfection. The crowd is "sometimes," so it might not be empty, but it's the one to aim for. The 15th is similar, but with a light cross-shore, so the 14th is the pick of the whole 16-day window. It's a long way out, so keep your fingers crossed, but it's the best look we've got.

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.
