The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Hanalei Bay over the next couple of weeks.
We're looking at a pretty drawn-out run of surf here on the North Shore of Kauai. The water's sitting at about average for this time of year, so don't expect any surprises when you jump in. The overall pattern is one of persistent, moderate trade-wind swell, but it's gonna be a bit of a mixed bag with the winds and the quality.
First up, Monday the 27th of July. It's small, with a 4ft swell from the East, but it's got a 14-second period on it, which is proper groundswell energy. The wind is a bit of a cross-off from the East, which is clean enough, but the combined energy is only moderate at 841 and the tide might be a bit off. Not the best start, but you can get a wave if you're keen.
Tuesday the 28th sees the swell bump up to a solid 7ft, still from the East and with a 13-second period. The energy jumps up strong to 1586. The problem is the wind is a cross-shore and there's a risk of thunderstorms. The size is getting up there, so it's more for the advanced crew.
Now, Wednesday the 29th of July is where it gets interesting, and this is the standout in the first week. The swell is 8ft to 8ft from the ENE, with a period of 10-11 seconds. The wind turns light and onshore from the North in the morning, swinging to the Northwest in the afternoon. That's glassy, offshore conditions for Hanalei Bay. The energy is strong at 1291. This is the pick of the first week. It's a proper, powerful wave with clean surfaces. Just be aware it's big enough to be for experienced surfers only.
The rest of the week into the weekend drops off quickly. Thursday the 30th sees the swell shrink to 5ft, and the period falls to a short, weak 8 seconds. The energy is low at 347. The wind stays clean, but it's a shadow of Wednesday. Friday and Saturday are similar, with 5ft to 7ft from the East, but the period is still short at 8 seconds. The wind is a moderate cross-off, so it's not messy, but it lacks the punch of the mid-week swell.
The second week is a bit of a waiting game. There's a long flat spell from Sunday the 2nd of August through to about Wednesday the 7th of August. The swell is small, generally 3ft to 6ft, with short periods of 8-10 seconds. The energy is low to moderate. The wind is a constant cross-off, so it's always clean, but the waves are just not there.
The next potential highlight comes in the third week. On Monday the 10th of August, the swell builds back to 6ft to 7ft, from the ENE with an 8-second period. The energy is moderate at 593. The wind is a clean cross-off again. Then on Tuesday the 11th of August, the swell holds at 7ft, with the energy jumping up to a strong 1021. The wind stays light and cross-off from the East. This looks like a promising run of consistent, clean, chest-to-head-high surf. It's not the same quality as the 29th, but it's the best bet for the second week.
So, if you're looking for the best day, lock in Wednesday the 29th of July. The offshore winds, the size, and the groundswell energy are a proper combo. For the second week, keep an eye on Monday the 10th and Tuesday the 11th of August for a return to cleaner, fun-sized waves.
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.
