The Lowdown
Alright, this is Rusty, your local surf reporter, looking at the next 16 days. The first week is a total washout. We've got a solid run of poor conditions from the 26th of July through the end of the month, with strong winds and lumpy, cross-onshore slop. The energy is there, but it's just not surfable. We're looking at a gap of nearly a week before things start to turn.
The Island is a consistent reef break, and it's exposed to the south-west swell, so it's always in the conversation. The water temp is about 60°F, which is pretty normal for this time of year.
The first real flicker of hope comes on the morning of Wednesday, the 30th of July. We've got a clean 5-foot swell from the SW with a period of 13 seconds, and the wind is a light cross-offshore from the NE. The water will be clean, and the combined swell energy is moderate (758). It's a proper surfable window, but the conditions are still a bit marginal for a standout.
Then, on the 31st of July, the swell drops to 3 feet, and while the wind is okay, the energy is weak. Saturday the 1st of August is a no-go with strong cross-shore winds.
The next real chance is on the morning of Tuesday, the 4th of August. This is the one to get excited about. The Island is looking like a true standout. The swell is 5 feet from the SW with a 13-second period, and the wind is glassy (5 mph from the SE). That's the kind of clean, glassy surface that makes a reef break perfect. The combined energy is a solid 792, and the conditions are forecast to be very good. It's a moderate size, so it's not just for experts, but the reef means you need to know your stuff. Crowds are possible at The Island, but on a Tuesday morning, it might be pretty quiet.
The next morning, Wednesday the 5th of August, is also looking excellent. The swell is a touch bigger at 5 feet from the SW, with a long 16-second period. The wind is a light cross-offshore from the NE, keeping the waves clean. The combined energy jumps to 1340, which is strong. This is another true standout. That long period groundswell will wrap nicely into the reef, giving some real shape. The morning is for experienced surfers, as the forecast says.
The second week gets a bit wild, but not in a good way. The 10th of August brings a massive 10-foot swell from the WSW with a 20-second period, but the wind is a howling 25 mph cross-onshore. The combined energy is astronomical (6034), but it's a total mess. That setup is more interesting for kite surfing than paddle surfing.
So, to sum it up: the first week is a dud. The clear standouts are the morning of Tuesday the 4th of August for its glassy conditions, and the morning of Wednesday the 5th of August for the quality of the long-period groundswell. Get out there if you can.
Rusty.

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