The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Right off the bat, the first few days are a bit of a write-off. We’ve got a tiny, weak SSW swell rolling in, but the wind is howling from the ENE at 25 mph. That’s a strong offshore breeze, which sounds good, but it’s making it a real battle to paddle into anything. The energy is weak, sitting around 196 (moderate). For a beginner-friendly spot like Waikiki, that’s just not worth the hassle.
We’re in a bit of a dry spell until the 20th of July. That Monday morning shows a little more promise. The wind drops to 16 mph from the ENE, still offshore, and the swell bumps up to 2ft from the S with a 14-second period. The energy jumps to 360 (moderate), and the forecast is for good surf. It’s still small, but it’ll be clean. The afternoon gets a bit more size (3ft) but the wind picks up, so the morning is the call.
The standouts, and I mean the real standouts, are much later in the window. On the 28th of July, we see a serious pulse of east swell. The morning brings 7ft at 14 seconds from the E, with a clean 16 mph offshore breeze. The energy is a massive 2161 (strong). But here’s the catch—that’s too big for Waikiki. The guidance says it’s too big for the break. This is a warning for the experienced crew only. The 30th of July also has size, with 8ft from the SSE, but the period is a short 8 seconds, which means it’ll be a bit of a mess. The wind is light, though, so it’s clean.
For the best all-rounder, I’m looking at the 31st of July, Friday morning. The swell drops to a manageable 2ft from the SSW, but the period is a very long 16 seconds. That’s proper groundswell energy. The wind is a gentle 9 mph from the E, keeping it clean. The energy is 223 (moderate). It’s small, but with that long period, it’ll have some punch and shape, and it’s a lot more user-friendly than the 7ft+ stuff. The water temperature is sitting at 80°, which is about normal for this time of year.
So, to sum it up: the first week is a slow grind with small, clean but weak surf. The second week has a big swell event that’s only for experts. The best bet for the average surfer is the 31st of July morning, with those long-period lines and light winds. Keep an eye on that one, but don’t get too amped for the early days.

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.
