The Lowdown

G’day, Rusty here. Let’s break down what’s cooking for Omaezaki over the next couple of weeks.

Right off the bat, Wednesday the 12th is a dead loss. Rain showers and a fresh cross-off breeze with only 3ft to 4ft of short-period swell means the ocean’s a mess. No point paddling out. The combined energy is weak (352 and 293) and the wave comment says it all. Thursday morning the 13th looks a touch better, with offshore wind from the ENE around 12 mph, and a clean 3ft SSW swell (period 10 seconds). The energy is still moderate (294), but the wind is the key – glassy offshore makes it rideable. Not a standout, but a decent session for a beginner or someone looking to get wet. Afternoon turns cross-off and the swell drops, so morning is the call.

Friday the 14th brings another clean morning with offshore ENE wind at 12 mph, swell dropping to 3ft but shifting to E (299 energy). Again, not huge, but clean. Saturday the 15th the swell picks up to 5ft from the E, but the wind is cross-off at 16 mph, and the energy jumps to 575 (moderate). The wave comment is marginal, so it’s a bit of a gamble – maybe for the more experienced.

Now, here’s the one that stands out. Sunday morning the 16th. Omaezaki (Japan) – this is the pick of the whole forecast. Swell hits 6ft from the E, period 10 seconds, combined energy of 1026 (strong), and the wind is offshore from the ENE at only 6 mph. The wave comment says “excellent surf conditions for experienced surfers.” That’s a clean, powerful, offshore morning for those who can handle the size. Water temperature is 82°, which is about average for this time of year, so no need to suit up heavy. The crowds are sometimes present, so you might have a few others on it, but that’s Omaezaki.

After Sunday, the week drops off. Monday the 17th has a clean 4ft morning but the energy is lower (382) and the wind is cross-off, so it’s okay but nothing special. From Tuesday the 18th through the end of the week, it’s all onshore junk – SW wind, tiny swell, poor conditions. The energy drops to 144 and below. There’s a gap of about four days with no real quality surf.

Looking into the second week, Friday the 21st morning shows a pulse of 7ft SW swell with a short 7-second period, and east wind at 6 mph cross-off, giving energy of 484. The wave comment says “expect good surf conditions” but the period is short, so it’ll be lumpy. Afternoon on the 21st jumps to 8ft but with onshore SW wind at 12 mph – that’s a mess and only for experts. Saturday the 22nd has a 5ft cross-shore, but the energy is moderate and the wind is light, so it’s marginal. Sunday the 23rd morning is the better of that late run – 4ft SSW swell, cross-off ESE wind at 9 mph, clean with 216 energy, but it’s ordinary. The last few days of the forecast are all onshore slop, too small and blown out.

Overall, Sunday morning the 16th is the clear standout – that’s your session. The rest of the run is patchy, but Surf’s not dead, just waiting for the right moment.

Rusty.

Information about the Omaezaki Surf forecast

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

Omaezaki is 1 km (1 miles) from Oyama. If you plan a holiday in Shizuoka, look for hotels and other accommodation in Oyama. Oyama has rooms for a wide range of budgets as well as car hire and transport links.
