Table - best surf conditions forecast for Dunes over the next 16 days.
Alright, let’s break down what’s in store. Only one spot here, Dunes – a consistent reef break that works best when the swell comes from the southwest. Water temp is 75°F, right where it should be for this time of year.
Wednesday morning, July 8th, we’re looking at about 5ft of southwest groundswell with a 15-second period – those long lines will wrap in real nice. Combined energy is moderate at 779, and the wind is light cross-offshore from the east at 6 mph. Clean conditions. Crowds can show up sometimes, so you might have company. That Wednesday morning window is your first good call.
Thursday morning, July 9th, the swell bumps to 5ft from the west-southwest, 16-second period – very long groundswell. Energy goes up to 1184, solid. Light cross-off east wind at 9 mph keeps it clean. Another good session, but watch the tide.
Friday, July 10th, is the standout. Morning has 5ft WSW swell at 14 seconds, with a clean 12 mph southeast offshore wind. Then Friday afternoon? Dead glassy – wind drops to 3 mph from the north, swell eases to 4ft but still 14 seconds. Energy is 528, but those conditions are as good as it gets. That afternoon glass-off is a treasure.
Saturday morning, July 11th, drops to 3ft from the WSW at 13 seconds. Clean with light cross-off east wind, but smaller. Energy 291. Afternoon goes ordinary.
Sunday and Monday, July 12th and 13th, are small. Sunday morning has 2ft SW swell, clean but weak. Monday morning has 2ft SW swell but a very long 18-second period – energy 381. Long waits between sets, but the wave shape at the reef could be sweet with light offshore wind.
Tuesday July 14th through Thursday July 16th, we’re between 3ft and 4ft, mostly SW, periods 13–16 seconds. Winds get stronger, mostly cross-off or cross-on – quality drops.
Friday July 17th, Saturday July 18th: back to 4–4ft from SW/WSW, 13–14 seconds. Saturday morning has clean offshore southeast wind at 6 mph – a decent little session.
Now, the big one: Monday July 20th. Morning brings 7ft from the WSW at 15 seconds, energy 1786 – strong. Afternoon pumps up to 7ft from the SW at 16 seconds, energy 2233 – very strong. Wind is offshore from the SSE at 16 mph, so it’ll be clean, but this is too big for most. Experts only.
Swell stays solid Tuesday July 21st (6ft, 14 seconds, 1533 energy) with cross-off wind – still expert territory. Then it fades through the week, with Thursday July 23rd morning offering a final clean 4ft SW swell with offshore wind – a nice finish.
Your best bet: Friday July 10th afternoon, glassy and clean with that 4ft southwest groundswell. If you’re experienced and want a challenge, Monday July 20th afternoon is big and clean.

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