Table - best surf conditions forecast for Sul over the next 16 days.
The Lowdown
Alright, let's size up what Sul has cooking for the next couple of weeks. The water temp is 78°, which is about 2° above the normal for this time of year. So, it's a touch warmer than average, but nothing extreme.
To be straight up, the outlook is pretty grim for most of this stretch. There are no good options at the very start. The first several days are a total washout, with light cross-onshore winds and tiny, weak swell. You’re looking at a gap of about a week before anything even gets close to being worth a paddle out.
There is a bump in swell energy on Wednesday the 12th, with a combined energy of 276 (moderate), but it’s coming with a cross shore wind and a period of just 6 seconds, so it won't be clean. That session is a miss. The following week gets a bit more energy, but the winds stay mostly cross to cross-on, messing up the surface.
The only real standout is on Thursday the 20th. The morning is glassy with a 3ft swell from the east, period of 8 seconds. The combined energy is 290 (moderate), and with zero wind, it will be clean as a whistle. That’s the morning to aim for. Remember, Sul is an inconsistent reef break, so you have to be on it when it's working. A Thursday morning means crowds are possible, but not gonna be as packed as a weekend.
After that, it’s back into onshore chop and poor conditions right through to the 24th. There’s nothing else worth getting excited about. It’s a tough run with only that one Thursday window offering any real hope for a clean, rideable wave.

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