The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this outlook for the next 16 days at Waikiki is a real mixed bag, and it’s mostly a waiting game. The first week and a half is pretty grim, with a lot of weak, short-period slop blown out by onshore winds. There’s a spark of hope right at the end, but you’ll need some patience.
For the first ten days, from Tuesday the 14th of July right through to about Thursday the 23rd, it’s honestly a write-off for any decent paddle surf. The swell is small, mostly under 3 feet, and the period is short (7-10 seconds), so the waves are weak and lack any punch. The combined swell energy is low to moderate – mostly in the 40-170 range – and the wind is predominantly cross or cross-onshore, making everything lumpy and choppy. There’s a brief window on the morning of Saturday the 18th with a light offshore, but the swell is still tiny at 2 feet, so it’s only just surfable and very ordinary. You’d be better off with a kite on most of these days, given the persistent wind and small, poor-quality waves.
Then you’ve got a real gap – from the afternoon of the 23rd through to the 26th, there’s really nothing to recommend. The wind swings onshore again, and the swell stays messy.
Now, hold on to your board, because things finally look up on Monday the 27th of July. That’s your standout day. The morning brings a moderate offshore breeze from the WSW, cleaning up a 4-foot east swell with a period of 11 seconds. That’s proper groundswell energy, giving the waves shape and power. The combined energy jumps to 326, which is moderate to strong, and the offshore wind will keep the faces clean. This is the best surf on offer – a solid, fun-size wave for intermediates and above. The afternoon looks good too, with a similar 4-foot east swell and that offshore wind holding. Crowds are possible here, so get in early.
The following morning, Tuesday the 28th, is a bit more marginal with a cross-on breeze, but Wednesday the 29th of July has a real treat: glassy conditions and a 3-foot swell from the ESE with a long 11-second period. The combined energy is 259, and with the wind flat, it’ll be clean and inviting. That’s a close second for the best session.
For the water temp, it’s about average for this time of year, so no surprises there.
So, to wrap it up: the first ten days are a bust. Don’t bother. Save your energy for Monday the 27th and Wednesday the 29th. Those are the only windows where Waikiki will show you what it’s got.
Rusty.

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.
