The Lowdown

Alright, Rusty here talkin’ about what’s cookin’ at Oaro.

Water’s sittin’ right on normal at 10°, so no surprises there. Let’s get into the week ahead.

It gets started on Thursday afternoon, the 13th. Glassy flat calm, a tiny 3ft of short-period ENE swell. The energy’s weak (226), so it’s all about that clean surface for a little fun on a small board. Nice to just paddle out.

Friday the 14th morning has a smaller 2ft wave with glassy conditions but real weak energy (123). Afternoon turns onshore and messy – pass on it.

Saturday the 15th morning is a weird one: a tiny 1ft wave on a super long 17-second period. That’s a long-period groundswell for a beach, so it’ll break straight, and the energy is only moderate (168). Glassy wind keeps it tidy for a log, though. Afternoon gets to 3ft but with a cross-shore, so it’s just okay.

Sunday the 16th starts to get interesting. That morning shows a 7ft southerly swell with strong moderate energy (717) and a 9 mph cross-offshore breeze. That’ll be clean and punchy, but at 7ft it’s pushin’ into intermediate territory, and the period is short (8s), so it’ll be a bit lumpy but fun if you want juice. Afternoon drops to 6ft, still clean.

Monday the 17th is a real winner. Morning glass is clean offshores with a 3ft SSW groundswell on a beautiful 15-second period. Energy is strong (674) – proper groundswell. Real shape and power, and those long lulls make paddlin’ easy. The afternoon holds at 6ft with a clean cross-off.

Now, the clear standout: Wednesday morning, the 19th. We’ve got 5ft of southerly swell with a *very* long 16-second period. The combined energy is huge at 2085 – that’s serious power. The wind is a light offshore cross-off, keepin’ it clean. This is excellent for experienced surfers – the size is manageable but that period makes every wave pack a punch. Circle this one.

The run keeps goin’. Thursday the 20th morning brings 5ft of 12-second groundswell with glassy conditions and good energy (712) – another cracker. Friday the 21st morning is glassy again with 4ft of long-period 14-second swell (586 energy) – real clean and fun.

The second week trails off a bit. The weekend looks smaller, with some 2ft to 3ft waves, but the wind mostly stays friendly. Tuesday the 25th afternoon picks up a little with 5ft of NE windswell and a clean offshore breeze.

Heads up: Sunday the 23rd afternoon has a nasty 19 mph cross-offshore wind – that one’s a mess. Thursday the 27th is onshore and choppy, so skip it.

So, your top call is Wednesday morning the 19th – big groundswell, clean, and powerful. Monday morning the 17th and Thursday morning the 20th are also excellent. The rest is either too small or a bit average, but get out there when it’s glassy and you’ll have a good time.

Rusty, out.

Information about the Oaro Surf forecast

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

Oaro is 116 km (72 miles) from the city of Blenheim. If you plan a holiday in Kaikoura and Marlborough, look for hotels and other accommodation in Blenheim. Blenheim has rooms for a wide range of budgets as well as car hire and transport links.
