The Lowdown

Alright, Rusty here. Let's talk about what's coming up for Waikiki.

We've got a bit of a slow start ahead. For the next week or so, the surf is going to be small and pretty ordinary. The trade winds are blowing steady, keeping things clean but the wave heights are tiny, barely a push. The real standouts don't start showing up until we get to the very end of the period. The best of the best is shaping up for Monday the 28th and Tuesday the 29th, with some real glassy conditions and a solid kick in energy.

The water temp is sitting at a warm 81.1°, which is pretty much spot on for this time of year, so no surprises there.

Waikiki (Oahu) starts off with some clean but tiny waves. Monday the 14th we’ve got a 1.0ft SW swell with a crazy long 23-second period. That's a lot of time between sets, and not much push when they do come. Combined swell energy is weak at 135. The wind is a moderate offshore from the ENE, so the surface will be clean, but you’ll be doing a lot of waiting. By Monday afternoon it picks up slightly to 1.6ft, still a long 22-second period, and energy bumps to a moderate 288. Conditions improve to a gentle offshore, and it's looking better.

Tuesday the 15th morning has a 2.3ft SW swell with a 20-second period. The energy is now a moderate 438. Winds stay moderate offshore. It's surfable but nothing to write home about. The pattern holds through the middle of the week: small waist-high waves, long periods, and fresh offshore winds. It’s clean, but you need a longboard and patience. Combined energy stays in the moderate range, topping out around 589 on Wednesday afternoon.

Thursday the 17th and Friday the 18th see the swell holding at around 2.3ft to 3.3ft, but the wind shifts to a cross-offshore direction. It's still clean, but the quality feels a bit off. The swell direction shifts slightly to SSW. The combined energy is moderate, getting up to 638 on Friday morning, but the wave comment says it's marginal. It’s not bad, just not great.

Saturday the 19th and Sunday the 20th are more of the same. Small SSW swell, fresh trades, clean but uninspiring. The energy drops back to the mid-300s to low-400s by Sunday. It's a longboard cruise if you’re desperate for a paddle.

Monday the 21st and Tuesday the 22nd are a low point. The swell drops to 2.3ft to 2.6ft, the period shortens to 13-14 seconds, and the wind is a strong offshore from the ENE, up to 25 mph. Combined energy is down to 203-280. The wind is so strong it makes paddling out a real chore. The surf is poor. Not worth it.

Then, Wednesday the 23rd is a big red flag for Waikiki. The swell jumps to 6.9ft from the east with a short 11-second period. Combined energy is a strong 1253. The wind is a fresh offshore, but the wave comment itself warns the swell is predicted to be too big for this break. This is expert-only territory, if anyone can even get out. It’s likely a washing machine. I'd give this one a wide berth unless you're a seasoned charger and know the channel well.

After that blow-out, we get a reset on Thursday the 24th with a 2.3ft SW swell, 16-second period, and moderate energy of 330. It’s back to small and clean.

Now, the real highlight. From Friday the 25th through the end of the period, things get special. Friday morning has a 2.6ft SSW swell, 15-second period, with a moderate offshore breeze from the NE. Combined energy is 304. It’s clean and fun.

Saturday the 26th is where it starts to shine. The wind drops right out. Saturday morning it's glassy with a slight air from the ENE at only 3 mph. The swell is 2.6ft from the SSW, 15-second period, and combined energy is a moderate 350. Saturday afternoon is also glassy from the NNE. The surface will be like a mirror. This is the kind of day you wait for.

Sunday the 27th morning is dead calm. Zero wind, glassy conditions. A 3.0ft SSW swell with a 16-second period, combined energy of 428. It doesn't get much cleaner.

Monday the 28th is the absolute standout. Monday morning brings a 2.3ft SW swell, but the period is a very long 18 seconds, and the energy jumps to a strong 546. The wind is a light offshore from the NNE. Expect very good surf conditions. Monday afternoon is even better: glassy conditions with a light west wind, the swell bumps to 3.3ft from the SSW, period of 18 seconds, and combined energy hits a strong 736. This is the pick of the fortnight. Clean, glassy, with some real push behind it.

Tuesday the 29th holds the quality. Morning is glassy with a 3.0ft SSW swell, 16-second period, and strong energy of 637. Tuesday afternoon

Information about the Waikiki Surf forecast

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

Waikiki is 5 km (3 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
