The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks. We’re talking about a single spot here, Secret Harbour, so let’s get into it.

The first week is a bit of a mixed bag, but there are some real gems hiding in there if you’re patient. The water is sitting at 64°, which is a bit colder than normal for this time of year, so grab the thicker wetsuit.

We’ve got a bit of a slow start. The 25th and 26th of July are a write-off with strong, nasty winds and poor conditions. Don’t bother. The 27th is still marginal, but it’s a step in the right direction.

Now, Tuesday the 28th of July is a standout. The morning has a clean 6 ft swell from the WSW with a light cross-offshore breeze, and the afternoon turns absolutely glassy with a 5 ft swell. The combined energy is moderate (1117), and with that 14-second period, the waves will have some real push. This is the kind of day you book off work for. The afternoon session is the pick of the bunch.

The 29th of July is another solid day. Wednesday morning has a clean 4 ft swell with a moderate offshore wind, and the afternoon gets even better with a 5 ft swell and a 17-second groundswell period. That’s proper long-period energy, so the waves will be lined up and powerful. Keep an eye out for the sets, as they’ll be spaced out, making the paddle out easy.

The 30th and 31st are a bit more marginal. The swell drops a little, and the winds aren’t as clean, so it’s more of a ‘check the cams’ situation.

August 1st is a wildcard. The morning brings a glassy 8 ft swell from the SW, but with light rain. That’s a big, clean, powerful wave. The combined energy is very strong (2193). This is for the experienced crew only. The afternoon, however, gets hammered by a 25 mph cross-offshore wind, so it’s a morning mission only.

The 3rd of August is a sneaky good day. Monday morning is glassy with a 5 ft swell from the WSW. Perfect conditions for a quiet session.

The 4th of August has a big, 20-second period swell (8 ft), but the wind is messy. It’s a powerful, long-period groundswell, but the chop will make it tricky. Not the best.

The 7th of August is another absolute standout. Friday morning has a clean 8 ft swell with a gentle offshore wind, and the afternoon is glassy with a 7 ft swell. The combined energy is very strong (2593 and 2133). This is a special day, and the afternoon glass-off is the one to chase.

The 9th of August is a total no-go. The wind is a near-gale, and the swell is a massive 20 ft to 21 ft. The combined energy is off the charts (11059 and 24800), but it’s way too big and blown out. This is kite-surfing territory, not for a paddle.

Best of the best: Without a doubt, Tuesday 28th July (afternoon) and Friday 7th August (afternoon) are the two standouts. Both offer glassy, clean conditions with solid, long-period swell. Get in the water.

Rusty.

Information about the Secret Harbour Surf forecast

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