Updates in  hr  min  s Forecast update imminent

Alright, Rusty here. Let’s break down what’s coming for Ikumi Beach over the next couple weeks.

It starts off real small and ordinary. Your first chance to get wet is Saturday morning, but it’s only 1 ft from the ESE with a weak 9 second period and the combined energy is tiny (34). Water temp is 77°F, about normal for the time of year. Wind is glassy from the SE at just 3 mph, so it’ll look pretty, but there’s nothing behind it. This spot is *inconsistent* and *often* crowded, so this isn’t worth the drive.

Saturday afternoon is a little bigger at 3 ft from the SE, but the period drops to a weak 4 seconds (energy 61) – surfable, but nothing special. Sunday is poor all day with light cross-onshore breezes – small and messy.

Now, Monday afternoon, 6 July gets interesting. Swell builds to 3 ft from the SE, and the period jumps to 14 seconds – proper groundswell. Combined energy is moderate at 342. The wind goes cross-offshore from the WSW at 6 mph, cleaning it up nice. The longer period means longer waits between sets, but at a beach break, it can run a bit straight. Still, this is your first good window.

Then the big stuff arrives. Tuesday 7 July shows 3 ft at a 17 second period – very long period groundswell – energy jumps to 1106. Winds are light cross-onshore, so not perfect. Tuesday afternoon is 5 ft at the same period, energy 1646. This is solid.

Wednesday 8 July goes big: 10 ft in the morning, 12 ft in the afternoon from the SE, period hitting 18 seconds. Energy is 6914. That’s massive. Wind is onshore ESE at 6 mph, but it’s still surfable for experts. 3 ft and up is for experienced surfers only; anything over 8 ft is strictly expert territory. This continues through Thursday 9 July (12 ft), Friday 10 July (13 ft), and Saturday 11 July (12 ft) – all with very long periods and extreme energy (up to 10,352 on Friday afternoon). Experts only.

The standout, the one I’d circle, is Sunday morning, 12 July. Swell drops to 8 ft from the SSW with a 14 second period – still a powerful groundswell, but way more manageable. Energy is 2260. And the wind? Glassy from the ESE at 3 mph. That’s about as clean as it gets. This is the pick of the whole forecast: excellent for experienced surfers. The break is *inconsistent*, but when it’s glassy and this size, those sets will be worth waiting for.

After that, Monday 13 July still offers 4 ft from the SSW with an 11 second period and glassy morning winds – a good option for a wider range of surfers. Energy is moderate at 465. Tuesday 14 July drops to 3 ft and fades through the rest of the week. From Wednesday onward, it’s small, weak, and not worth chasing – glassy conditions won’t save the lack of swell.

Bottom line: if you’ve got the skills, Sunday morning, 12 July is the clear standout with glassy conditions and a solid 8 ft SSW groundswell. For something earlier, Monday afternoon, 6 July offers a fun, clean window. The big surf from 8–11 July is strictly for experts.

Stay safe out there.

Information about the Ikumi Beach Surf forecast

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

Ikumi Beach is 30 km (19 miles) from Muroto. If you plan a holiday in Shikoku, look for hotels and other accommodation in Muroto. Muroto has rooms for a wide range of budgets as well as car hire and transport links.
