The Lowdown
Alright, so the next 16 days are mostly a no-go for clean waves. First week: forget it—swell is small, period is short, winds are cross and chop it all up. You’ve got some longer period S swell trying to push through on the 12th and 13th, but it’s only 0.9–1.1m with fresh cross-shore winds. The scores are all zeros, combined energy moderate at best.
From Friday the 14th, the swell jumps to 2.3–3.0m from the ENE, but it’s short period and driven by strong 40–45 km/h cross-shore winds. Energy climbs into the strong range—900 to over 1600 by the 18th—but the surface is messy cross-chop. Good for power, bad for trim.
Best shot is Wednesday morning the 19th: 3.0m ENE swell, 9-second period, 1333 energy, winds drop to a fresh 35 km/h cross-shore, and the report says wind and tide are favorable but the swell might be too big for this spot. That’s an expert-only window. The afternoon and Thursday fade with marginal conditions and lumpy 2.5m swell. If you’re skilled and hungry, that Wednesday morning is the one.

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