The Lowdown

Alright folks, Rusty here. Let’s get into it.

First up, the outlook for Kolekole. This is a river mouth break, fairly consistent, but we’re looking at a real rough patch to kick things off. The water temp is sitting at 80°F which is about normal for this time of year, so no surprises there.

The first few days are a write-off. From Tuesday the 21st to Thursday the 24th, we’ve got weak little 4ft to 5ft windswell out of the east, with periods around 7 seconds. On top of that, the wind is cross-on or onshore, making for choppy, messy conditions. The combined energy is weak, between 246 and 328, so it’s just not worth paddling out for. The wave comment says it all: poor surf. It’s a no-go.

Friday the 24th afternoon shows a little something. The swell bumps up to 6ft from the ENE, period 8 seconds, and the energy jumps to 749 (moderate). Wind is onshore but light, so it’s still marginal. This isn’t a standout, but it’s the first sign of life.

Saturday the 25th morning holds 5ft from the NE, period 8 seconds, energy 592. Again, light onshore wind, still marginal. It’s not clean, not really firing. Your best bet is to wait.

Now, here’s where it gets interesting. Sunday the 26th morning brings a proper groundswell. 6ft from the east, but the period jumps to 16 seconds – that’s a very long period. The energy is 1754 (strong). Wind is light onshore. This is a standout. The long period means the waves will have real shape and power, and at this size, it’s not too big for intermediates. The caveat is that long period east swell can be a bit too straight at a beach break, but at a river mouth like Kolekole, it’s often a good thing. This is the best session on offer.

Monday the 27th morning keeps it going. Still 7ft from the east, period 14 seconds, energy 2000 (strong). Wind is light cross-on, just a few ripples on the face. This is also a standout. The swell is getting bigger – 7ft is now getting into expert territory if you’re not used to it. The energy is powerful, and the longer period will give you clean, lined-up waves. Crowds are possible here, so get in early.

The next few days hold onto that swell. Tuesday the 28th and Wednesday the 29th have 7ft from the east, periods 13 to 11 seconds, and energy stays strong (1056 to 1486). Wind is cross-on but light. It’s still surfable, but the quality is a step down from the weekend. The swell is easing, and the period is dropping.

From Thursday the 30th onward, the swell fades. 4ft, then 3ft, and the energy drops to 226. The wind goes onshore or cross-on again. The comments start saying “poor surf” again. It’s a long drop-off.

There’s a tease for the first week of August. The 1st of August has 7ft and 7ft from the east, but the period is short (8 seconds), and the wind is onshore or cross-on. The energy is moderate (572 to 650) but the wave comment says “poor” or “marginal.” It’s a messy, short-period windswell. Not one to get excited about.

The 2nd of August has 7ft to 8ft from the ENE, period 9 seconds, energy 902 to 924. Still just marginal. The period is too short for that size, so it’s going to be a crumbly, bumpy mess.

After that, the 3rd to the 5th of August just fades back into weak, choppy surf. The wind stays cross-on, energy drops below 400. It’s back to the poor conditions we started with.

So, the real standouts are Sunday the 26th and Monday the 27th. That’s the window. If you can get out then, you’ll be rewarded with solid, long-period groundswell and clean conditions. The rest of the 16 days is mostly a waiting game, with a few marginal windows that aren’t worth the paddle.

Stay patient, and keep an eye on the charts.

Rusty.

Information about the Kolekole Surf forecast

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

Kolekole is 19 km (12 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
