The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a sluggish start and a very long run of small, clean, but not very exciting surf. The real standout is a pocket of glassy, long-period groundswell in the middle of next week. The water temp is sitting at 82°F, which is about average for this time of year, so no surprises there.
The first real chance to get wet comes Saturday morning, the 15th, but let’s be honest – it’s a blowout. Campbells is showing a 3ft south swell, but that 28 mph northeast wind is a full-on gale. It’s offshore, sure, but you’ll be fighting for every paddle. The wave energy is weak (314) and the period is a long 13 seconds, which would be nice, but the wind makes it a no-go. The afternoon is even worse with 34 mph winds – forget it.
Sunday the 16th sees a bump in size to 5ft from the SSE, but the period drops to 9 seconds, making it a bit of a messy, wind-affected choice. The wind is cross-offshore, so it’s clean, but the energy is moderate (734) and not that well organised. It’s a marginal day, better for a longboard than a groveler.
The whole week from Monday the 17th through to Wednesday the 20th is a grind of small, clean, but ordinary surf. Swells are bouncing between 1ft and 3ft, mostly from the south and southwest with moderate cross-offshore breezes. The periods are long (14-18 seconds), which is a tease, but there just isn’t enough power. The combined energy sits in the low-to-mid hundreds, so it’s weak.
Now, here’s where it gets interesting. Thursday the 20th through to Saturday the 22nd, Campbells switches on. The swell stays around 2ft to 3ft from the SSW, but the period is a solid 16-17 seconds, and the wind goes glassy. That’s the magic formula. The combined energy climbs to 384, 321, and even 475 on Saturday morning. This is the best window. The break is a reef, so that long-period groundswell will wrap in nicely. It’s an inconsistent spot, so you’ll have to be patient, but when the sets come, they’ll be clean and well-shaped. Thursday afternoon and Friday morning with that glassy surface are the pick of the bunch. Crowds are often here, so expect company.
The following week, from Sunday the 23rd onward, the wind stays mostly cross-offshore, but the energy drops back into the 200-400 range, and the swell remains small. There are some longer-period pulses (14-18 seconds), but the wind is a bit stronger, and the quality fades back to marginal. The last few days of August into the 30th look poor, with weak energy (115-195) and bumpy wind conditions. It’s a frustrating end to the outlook.
So, the call: If you can get out Thursday the 20th through Saturday morning the 22nd, you’ll score the cleanest, glassiest, longest-period waves of the forecast. The rest is a waiting game.
Rusty.

Information about the Campbells Surf forecast
The above surf forecast table for Campbells provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Campbells can be found by selecting the local surf guide option on the grey menu. Our Campbells 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 (Campbells) 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 Campbells 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.
Campbells is 6 km (4 miles) from Makakilo City. If you plan a vacation in Oahu, look for hotels and other accommodation in Makakilo City. Makakilo City has rooms for a wide range of budgets as well as car hire and transport links.
