The Lowdown
Alright, buddy, Rusty here. Looking at the charts for Rabbit/Manana Island on Oahu’s East side, and I’ve got to say, it’s a rough 16 days ahead. The westerly trade winds are going to be a real pain, and there’s not much to get excited about.
The biggest problem is that persistent ENE wind. For the first week, it’s blowing a strong breeze, 25 to 28 mph, and it’s almost always cross or cross-onshore. That’s the kiss of death for any kind of clean surf. The water temp is pretty normal for the season, nothing to write home about.
Through the first few days, from Saturday the 1st to Tuesday the 4th, we’ve got swell from 8 ft down to 5 ft, coming from the E or ENE. The period is short, only 8 seconds, so it’s all windswell junk. The wave energy is moderate, with readings from 1107 down to 436 (combined energy of all swells directed here), but it’s all ruined by the wind. The waves are too big for beginners on the 1st and 2nd (over 5 ft), and with that wind, it’s a complete mess. Honestly, this looks more like a kite surfing day than a paddle surfing day.
The whole first week and into the second is a total loss. There’s a slight break on Wednesday morning the 5th, with the wind dropping to a gentle breeze, and the swell is 4 ft from the ENE, with a 10-second period. It’s a marginal 1/10, but there’s a risk of thunderstorms later. Don’t count on it.
After that, it’s the same old story. From the 10th of August onward, the swell drops below 5 ft, but the wind stays fresh and cross-onshore, 15 to 22 mph. The wave energy is weak, usually under 300 (combined energy of all swells directed here), and the period is a short 7-8 seconds. It’s just not going to work.
So, bottom line: there are no standouts. The consistency is there for Rabbit/Manana Island, but the quality is terrible. It’s a long, dry spell. Forecasts can change, but right now, I’d say save your wax and wait for a better window.
Rusty.

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