The Lowdown

Alright, let’s chew the fat on what’s ahead. It’s gonna be a flat spell for the most part, but there’s one little window that might just save your week.

Waikiki is the only game in town for this whole stretch, and for the first few days, it’s a total bust. Saturday the 22nd through Monday the 24th? Don’t even bother – no swell at all, and that 25 mph wind from the WSW on Saturday is going to make it feel like you’re at a kiteboarding spot. The combined energy is zip (0). Tuesday the 25th finally shows some pulse – a southeast groundswell with a very long 18-second period rolls in, energy is moderate (208), but the wind is a messy cross-onshore out of the north. It carries into Wednesday, with more energy (613 to 647), but same story – choppy and lumpy.

Thursday the 27th is the one to circle. Morning brings a light offshore breeze from the SW, cleaning up that 3ft southeast swell. The period is a respectable 12 seconds, and the energy sits at 310. By afternoon, it goes glassy with a light WNW wind, 3ft, 12 seconds, energy at 241. This is the standout of the entire outlook. Waikiki (Oahu) will be clean, and while the swell is coming from the southeast – not its ideal direction (NE) – it’s the best we’ve got. Crowds are *sometimes*, so expect a few folks out when it’s this clean.

Water temp is 51°F, which is about 4°F warmer than usual for this time of year – a touch warmer than normal, so you might be fine in a spring suit.

Friday the 28th and Saturday the 29th slide off quickly. Swell drops to 2ft, period shortens to 9-10 seconds, and the energy is weak (86 and 68). Conditions stay clean on the glassy Friday afternoon, but it’s really just small and nothing special.

From Sunday the 30th all the way through September 7th, it’s a desert. Swell barely holds at 2ft, period sits at 8-10 seconds, and the combined energy almost never cracks 100 – weak to nonexistent. The wind shifts around, but the surf is basically gone. There’s a brief glimmer on Thursday September 3rd afternoon with a moderate offshore from the SW, 2ft east swell, 10-second period, energy of 104 – surfable, but real ordinary. Then it’s back to flat and poor.

So here’s the takeaway: if you want a wave that’s worth paddling for, your only real shot is Thursday the 27th of August. Hit the morning for that offshore breeze or the afternoon for the glass – it’ll be clean, small, and rideable. Everything else in the next 16 days is either too small, too windy, or just plain flat.

Keep your eyes peeled, things can change quick.

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.
