The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the horizon for us right now.

To be straight up, this is a slow start that stretches into a long wait for anything decent. We’re looking at a solid week or more of pretty unexciting surf on offer here. The early days are all about small, weak swell and a lot of “poor” and “marginal” calls. The first recommendation doesn't even pop up until late in the game. So, sit tight.

The only real standout in the whole 16-day window comes right at the end of the run. On Thursday morning, the 24th of September, the swell starts to build properly. We’ll see chest to head-high waves pushing 6 ft from the east with a 10-second period. That’s a long period groundswell, which means better shaped, more powerful waves with decent energy behind them - we’re talking strong to very strong wave energy here (1179). The wind is a steady moderate breeze from the east holding it as cross-offshore, keeping the faces clean. This is the best surf on offer, and it’s a proper session for advanced surfers looking for some juice.

Following that, Friday the 25th and Saturday the 26th stay interesting with some very long period energy from the west-northwest. Friday afternoon sees a 20-second swell at 3 ft (1112 energy) and Saturday morning a 17-second swell at 4 ft (1052 energy). These are big, slow, powerful lines that will be breaking straight at a place like Hanalei Bay, which is a reef and point setup, so that’s actually a good thing – they’ll wrap in nicely and offer some long rides. The wind stays clean and cross-offshore. These are promising but less certain being further out, but they could be epic.

Water temp is sitting around 80°F, which is pretty much spot on average for this time of year.

So, there you have it. A long dry spell, but the last week of September should reward the patient with some serious quality. Keep an eye on that 24th and the following weekend.

Rusty.

Information about the Hanalei Bay Surf forecast

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