Alright, let’s get into it. I’m lookin’ at the only spot on the cards here: Ikumi Beach.

Right now, the surf story is pretty quiet. We’ve got some tiny, weak swell rollin’ in – nothing to write home about. The water temp is sittin’ around 76.1°, which is a little colder than usual for this time of year, so you’ll feel that slight chill if you’re used to warmer waters.

Let’s walk through it day by day.

Sunday morning, 5 July – Small 2.6ft swell from the SSW with a short period of 7 seconds. Combined energy is weak (82). The wind is glassy off the ENE, so the surface will be clean, but it’s inconsistent and the waves are ordinary. The afternoon turns messy with a cross-on breeze and risk of thunderstorms – not worth paddlin’ out.

Monday, 6 July – Still small. Morning brings a 2.0ft SE swell, but the period jumps to 15 seconds, which is a proper long-period groundswell. Energy picks up to 189, still moderate though. Wind is cross-off from the SW, so it’s clean. The afternoon turns glassy with light WNW winds, and the swell bumps to 3.0ft with 14 seconds and energy up to 459. That’s a decent little window – clean, calm, and a bit more push. This is a low-key standout for the early part of the week.

Tuesday, 7 July – The morning’s a bit messy with light cross-on wind and 3.3ft swell (period 12 seconds). Energy’s building to 593. The afternoon though – that’s the real pick of the day. Glassy conditions, 4.3ft swell from the SE at 15 seconds, and energy jumps to 1017. That’s moderate energy, but those clean conditions and a groundswell pulse will make for some fun, long rides. Best experienced surfers for this one, as the period is long and it’s a beach break, so expect some straight runners.

Wednesday, 8 July – Morning looks excellent for experienced surfers. Glassy, 6.9ft swell from the SE at 16 seconds – energy is 4139 (strong). This is serious groundswell. The afternoon though, it gets too big – 9.8ft with 17 seconds and energy hitting 5904. That’s strong, clean on the wind but too heavy for this break. It’s gonna be a washing machine for most. Kite surfers might be frothin’, but paddle surfers better be on their A-game or sit it out.

Thursday, 9 July – Swell stays big, 9.8ft from the SSE, period 16 seconds, energy over 6000. Wind is onshore from the ESE both morning and afternoon. This is big, powerful, and messy. Not recommended for paddlin’ out unless you’re a pro and know the spot well. Too much for most.

Friday, 10 July – Even bigger. 13.1ft swell from the S at 17 seconds, energy over 8000 in the morning and over 10000 in the afternoon. This is massive. Wind is light but cross-on in the afternoon – it’s a beast. Only for experts, and even then, it’s pushing limits. Also, the swell direction (S) is not ideal – this break works best with SE to ESE windswell.

Saturday, 11 July – Still huge. 13.1ft in the morning with glassy conditions, dropping to 11.5ft in the afternoon with a cross-shore breeze. Energy remains in the thousands. Too big for sensible surfing here.

Sunday, 12 July – Finally, the swell starts to drop. 8.2ft in the morning, glassy with cross-off wind, 15 seconds period, and energy at 2620. That’s still strong but more manageable for experienced surfers. Afternoon sees 5.2ft at 14 seconds, clean cross-off. This is the best window in the second week – still big, but cleaner and dropping.

Monday, 13 July – 3.9ft in the morning from the S at 11 seconds, glassy. Energy at 580. Good conditions, clean. Afternoon gets a bit smaller and

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.
