Alright folks, Rusty here. Let’s break down the next couple of weeks. It’s a grim start, with a long stretch of nothing much happening before we get a sniff of real surf.
The first proper chance you’ll have to paddle out is on Saturday afternoon, July 4th, at Kewalos. Water temp is sitting at a warm 80°, right about normal for the season. A clean but small 2ft S swell pushes in with a super long 20-second period. The combined energy of all swells is over 800 units, so there’s plenty of push for the reef. The wind is a cross-off from the ENE at 18 mph. That long period and the clean wind will make the lines hold up nicely, but this is an advanced wave, so only for those who know the reef.
Sunday the 5th offers a little more size at 3ft from the SSW, with a long 18-second period and even more energy (920 units). But the wind is stronger at 22 mph, and it’s flagged as poor surf. Clean, but not worth it.
From Monday the 6th through to around Saturday the 11th, we get hammered by a lumpy windswell. Swell heights sit between 5ft and 7ft, but the period is a short, snappy 7 to 8 seconds from the ENE. The wind is blowing the same direction at 18 to 25 mph, so it’s a messy, onshore mess. The energy is high (over 800 units at times), but this setup is far more interesting for kite surfing than paddle surfing. Surfers can give this one a miss.
A brief window opens on Sunday the 12th. A clean 3ft SSW swell with a lovely 16-second period rolls in. The combined energy sits around 700 units, moderate but well-organised. The wind is still cross-off, but only marginal quality. Probably the cleanest the reef will look all week.
Monday the 13th is similar: 3ft with a 15-second period from the SW. Again, the wind is cross-off, but only poor to marginal. Not a standout.
From Tuesday the 14th onward, we slide back into weak, short-period ENE windswell at 5ft to 6ft, with periods of just 7 seconds. The energy drops hard from over 600 units down to 250 by the weekend. The whole second week is a desert. By July 19th, the swell is a tiny 5ft with a 7-second period and energy under 400 units. That’s basically flat for a reef like this.
Best on offer? The Saturday afternoon, July 4th slot. Small, but the direction is perfect for the break, the swell is nicely lined up, and the wind is clean. The rest is a write-off.
This is Rusty, signing off.

Information about the Kewalos Surf forecast
The above surf forecast table for Kewalos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kewalos can be found by selecting the local surf guide option on the grey menu. Our Kewalos 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 (Kewalos) 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 Kewalos 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.
Kewalos 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.
