Alright folks, Rusty here. Let's take a long look at what's coming up for Ikumi Beach. We've got a bit of a slow start, but the end of the run is looking promising.

Right now, we're in a quiet patch. The first real chance for a wave is Monday afternoon, 6th July. It’s small, maybe 3 ft from the SE, but the wind goes glassy, which is a huge bonus. The water temp is 76°, which is a bit colder than we’d normally expect for this time of year. Monday morning is a write-off with risk of thunderstorms and a cross breeze.

Tuesday the 7th starts off with the best conditions we'll see for a few days. Tuesday morning is glassy offshore wind (ESE at 3 mph) with a 3 ft, 15-second SE groundswell. The combined energy is moderate (621), and the glassy conditions will make for clean, fun little waves. This is your window for a longboard or a fish. Tuesday afternoon the wind switches cross-onshore and the quality drops right off.

Then things get heavy. From Wednesday the 8th through to Saturday the 11th, we've got serious size rolling in. Wednesday morning is already 8 ft from the SE with a 17-second period, but it’s accompanied by onshore wind and messy. By Thursday the 9th, it's 10 ft from the SSE, and by Friday the 10th we're looking at 13 ft from the S with a massive combined energy of 10553. The comments say it’s too big for this break, and I have to agree. This is expert-only territory, and even then, it's going to be a washing machine. The ESE wind keeps it onshore and lumpy. This stretch is not one for the average punter—if you're into kiting, maybe it’s interesting, but for a paddle, it’s a pass.

We get a breather on Sunday the 12th. Sunday morning sees the swell dropping to 8 ft from the SSW with glassy conditions. This is the real standout of the first week. The wind is flat calm, the wave energy is still strong (2015), and the conditions are clean for experienced surfers. The 14-second period is solid groundswell, so expect some power and long waits, but the quality will be there.

After that, we settle into a long, quiet spell. From Monday the 13th right through to Thursday the 16th, we’re looking at small, inconsistent surf. The swell hangs around 3 ft to 4 ft, mostly from the S and ESE. There are some glassy mornings, but the wave energy is weak (under 300), so don’t expect much more than ankle-to-knee-high dribblers. The second half of July 17th is much the same.

Then, as we push into the third week, things start to look interesting again. Saturday the 18th morning brings a jump to 5 ft from the S with a 12-second period and glassy conditions. The energy picks up to 791. This is a promising sign. Sunday the 19th is the heavyweight of the second week. Sunday morning shows 10 ft from the ESE with a 13-second period and glassy offshore wind. The combined energy is 3320. It’s big, but with the glassy wind and ESE direction, this could be the session to circle on your calendar. Sunday afternoon drops to 8 ft, still clean. Monday the 20th is also clean (7 ft, glassy), but the wind tips cross-onshore in the afternoon and it gets too big again by Tuesday.

So the two true standouts: Tuesday morning the 7th for clean, small waves, and Sunday morning the 19th of July for the big, clean groundswell. That Sunday is the one to keep an eye on as it gets closer. The week in between is mostly a waiting game.

Rusty.

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.
