Alright, let’s get real about Duds Reef for the next couple of weeks. Honestly, mate, the outlook is a bit of a bust for us paddle surfers. We’re looking at a long stretch of pretty ordinary conditions, so don’t get your hopes up.
Right from the start on Monday, July 6th, it’s a write-off. We’ve got a 3 ft swell from the SSW with a solid 16-second period—so the energy is there, moderate at 803, and the period is juicy, but that ENE wind is hammering it at 22 mph straight cross-shore. It’s lumpy, messy, and there’s zero quality. That same picture repeats all week: swell heights bouncing around from 3 ft to 6 ft, mostly from the east or ENE, but that wind never lets up. It’s cross-shore, fresh, and just kills any chance of a clean face. The water’s sitting at 80°F, which is pretty average for this time of year.
Through the second week, into mid-July, the pattern barely shifts. The swell energy drops off into the 300s and 400s, so it’s weak. There are a few moments, like Monday July 13th morning, where the comment says "marginal" with a score of 1, but that’s about as good as it gets. We’re talking 3 ft SSW swell with 15-second period, and the wind backs off slightly to 16 mph, but still cross-shore. It’s not surfable, just less terrible.
The whole 16-day window is a blank run for reasonable surf. There are no standout days where the wind goes offshore, no glassy mornings. For a spot like Duds Reef that’s fairly consistent, this is unusual—it’s just a poor run of form. If the wind ever swings, this place can fire, but right now, unless you’re kiting, leave the boards at home.

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