Updates in hr min s Forecast update imminent
Alright, crew, let's talk about Duds Reef for the next 16 days. I've been staring at the charts, and I'm not gonna sugarcoat it – it's a long, flat grind. The entire forecast period is full of "poor surf conditions" with no real scores to speak of. We're lookin' at a solid 16-day gap where there's just nothin' worth gettin' wet for. For this spot, it's not unusual to see a dry spell like this, but that doesn't make it any easier to swallow.
So, the first day we see any action is Sunday morning, July 5th. There's a tiny 3 ft swell from the SSW, which is a good angle for this reef, and it's got some serious 18-second period – that's deep ocean groundswell. But here's the killer: the wind is howlin' cross-shore at 22 mph from the ENE. That's churnin' up a lumpy, grovelly cross-chop. The combined energy is moderate at 894, but with that wind, it's a total no-go. This same sad story plays out through Monday the 6th and Tuesday the 7th – a little bit of swell, but that same nasty 22 mph cross-wind. All "poor surf conditions."
By Wednesday the 8th, the wind gets even worse, hittin' 25 mph cross-shore, makin' a total mess. The swell does push up a bit, peakin' at 6 ft on the afternoon of the 10th, but that's a weak, short-period 7-second east-northeast windswell. Tied to that strong 22 mph cross-wind, it's just bumpy and ugly. The combined energy gets up to 605, still moderate, but for a guy on a surfboard, it's a write-off.
As we slide into the second week, the story doesn't change. It's either short-period windswell from the east or east-northeast, or small, long-period pulses from the south-southwest. The wind does ease up a bit toward the end, droppin' to around 12-15 mph cross-shore. The afternoon of July 16th and the 17th see a "Gentle breeze" from the east-northeast, which is the cleanest it gets, but with no decent swell behind it, you're just lookin' at a flat, rippled lake. The biggest day in that second week is Monday, July 20th, with a 5 ft, 7-second windswell and a cross-wind – still poor.
There are no standout days here, folks. This entire 16-day window is a total blank for decent, clean waves at Duds Reef. Save your gas and your energy. Forecasts can always flip, but as it stands right now, this is a proper dry spell.

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.
Duds Reef is 0 km (0 miles) from 'Ewa Beach. If you plan a vacation in Oahu, look for hotels and other accommodation in 'Ewa Beach. 'Ewa Beach has rooms for a wide range of budgets as well as car hire and transport links.
