The Lowdown
Alright, Rusty here. Let’s talk about what’s shaping up for the next couple of weeks.
We’ve got a bit of a quiet start, but don’t write it off. The first couple of days are all about clean, small waves at Waikiki. The water’s sitting at a warm 80.4°, pretty much average for this time of year, so no surprises there.
Thursday the 10th kicks off with an offshore breeze and a tiny 1.6ft swell from the southwest. It’s not big, but with an 18-second period, there’s some nice long-period energy in the water. The combined swell energy is moderate at 376. It’s more of a longboard glide than a punchy wave, but it’s clean.
Friday the 11th and Saturday the 12th stay in that same groove – small, clean, offshore winds keeping things tidy. Waikiki is very consistent, so you’ll always find something to ride, but don’t expect any barrels. The crowd’s often there, so bring your patience.
Sunday the 13th through Tuesday the 15th sees the swell bump up just a touch – 2.3ft from the southwest, with periods dropping to around 15-20 seconds. The wind stays offshore or cross-offshore, keeping the surface glassy. The combined energy climbs into the 400s, which is moderate but building.
Wednesday the 16th is where things get interesting. The swell pushes to 3.0ft, with a strong 18-second period and a combined energy of 628 (moderate to strong). The wind is a fresh offshore, so it’ll be clean but you’ll feel the breeze. Still, for Waikiki, this is a solid day of small but well-shaped waves.
Then we hit a bit of a lull from Thursday the 17th through Tuesday the 22nd. The wind picks up, especially on the 17th and 19th, with gusts up to 25 mph. The swell stays in the 2.3ft to 3.3ft range, but the conditions get more challenging. The waves are there, but it’s a bit of a battle with the wind.
Now, the standout – and I mean the real standout – is Wednesday the 23rd. We see a spike in swell: 5.9ft from the east, with a 12-second period. The combined energy is huge – 1311 (very strong). That’s a big jump. The wind is a light cross-offshore, so it’ll be clean. This is for experienced surfers only – 5.9ft at Waikiki is a serious step up, and the long period will make the sets pack a punch. This is the day to be in the water if you’ve got the skills.
Thursday the 24th and Friday the 25th settle back down but stay solid. The swell drops to 2.6ft-3.0ft from the south-southwest, with a nice 16-18 second period. Light winds and clean conditions. Combined energy is still strong, in the 400-672 range. This is your reward after the big Wednesday.
Best on offer: Wednesday the 23rd for the big, powerful east swell – but only for experts. Thursday the 24th is the best all-rounder: clean, moderate swell, and light winds. Good for anyone with a bit of experience.
Stay stoked.

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.
