The Lowdown
Alright, I’m looking at the 16-day forecast for the Waikiki area, and I gotta be straight with you — it’s a pretty tough stretch. The whole outlook is a long grind of small, weak waves, mostly from the east, with very little energy behind them. The water temperature is sitting around 51°, which is a touch warmer than normal for this time of year, so at least a quick dip won’t sting.
We’ve got a big gap of nearly no quality surf from the start until the very end of the first week. Honestly, the first time we see anything even close to "surfable" is on Wednesday, July 22nd. That morning, Waikiki has a small 2ft east swell, but it’s only got a short period of 8 seconds, and the combined energy is weak at 57. The wind is a light cross-offshore, keeping things clean, but it’s not going to get the heart racing. That’s the best you’ll see for days.
The pattern stays flat and uninspiring right through until the end of July. We get a few more clean mornings on July 28th and August 1st, but the swell is still tiny — 2ft to 3ft — with barely any push. The standouts are few and far between. The only real glimmer of hope comes on Saturday, August 1st, when a 3ft east swell with a 10-second period rolls in, and the wind goes light offshore from the south-southwest. The combined energy bumps up to 145 (moderate), and the surf is clean. For a beginner-friendly spot like Waikiki, that’s about as good as it gets in this window. It’s still small, but it’ll be the most fun you’ll have.
After that, the swell fades back into the doldrums. The second week is a real snoozer — nothing over 2ft, and most days are chopped up by onshore winds. The energy levels drop into the double digits, and by Tuesday, August 4th, it’s a fresh offshore wind, but the swell is only 1.0ft to 1ft, so it’s basically a flat day with a breeze.
Overall, there’s no true big swell, no stand-out session. The best bet is to wait for the first couple of days of August, but keep expectations low. This is a period where the surf is just not cooperating.

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.
