The Lowdown
Alright, it's Rusty. Let's get into it.
Look, I'm gonna be straight with you. The next 16 days are a tough run. We've got a lot of wind and not a lot of quality. The only break on the radar is Aileens, and it's a tricky one.
For Wednesday the 9th, the swell is around 4 ft from the west, but the wind is onshore at 6 mph and the combined energy is weak at (220). The water is a touch warmer than normal at 62°F, but the conditions are just poor. Thursday the 10th, we see a bump in swell to 7 ft from the WSW, and the energy jumps to moderate (741) in the morning and (804) in the afternoon, but that fresh cross-onshore wind at 16-22 mph will chop it up.
Friday the 11th is more of the same, with 5 ft west swell but cross-onshore breezes. Saturday the 12th, the swell hits 8 ft from the west with an 11-second period, giving us strong energy of (1439), but it's a messy cross-onshore situation. That's too big for beginners and the wind will make it a battle.
Sunday the 13th sees a drop-off, with only 3 ft and weak energy (287). We get a little break in the wind on Sunday morning with a light breeze from the NW, but it's cross-onshore. Still, it's only a 1 out of 10 on the marginal scale. The rest of that week and into the next is dominated by poor surf and moderate to fresh cross-onshore breezes.
There is one light at the end of the tunnel. Sunday, September 20th. Aileens is showing 5 ft from the west with a long 11-second period and clean conditions thanks to a cross-offshore wind from the SE. The combined energy is moderate (611). The swell direction (W) is close to the WSW optimum, and the period is solid. This is your best window, but keep in mind, Aileens is an advanced reef break that is inconsistent. For a surfer up to tackling a powerful, straight-breaking reef, this morning session looks the pick. Expect crowds to be likely. The following morning, Monday the 21st, also shows clean conditions, but then the wind swings and it's over.
Overall, we have a long gap of poor surf from now until the 20th. Then you get a couple of cleaner windows before it turns grotty again. For the breaks on the 20th and 21st, I'd be looking at the Aileens (Big Island) area for the best (but still only marginal) options. If the wind stays clean, those longer period swells will have some punch, but they can be tricky at this spot.
This is Rusty, signing off.

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