The Lowdown
G’day, Rusty here. Let’s look at what’s on the table for the next couple of weeks at Ohara. Honestly, the first few days are small and messy, and you’ll be scratching for anything clean. There’s a big pulse of swell around the 19th, but it’s way too big for this spot, and the wind is against you. The real gem is sitting on Tuesday the 22nd — that’s your standout. A solid, clean southwest groundswell with offshore winds, and it’s going to be worth the wait.
Right now, Monday the 14th — surf is tiny, 0.5m to 1.0m, with weak energy (168 to 291). Winds are cross-off, but there’s nothing doing. Tuesday the 15th is marginal, 0.7m, with questionable tides. The afternoon has a light breeze and clean-ish lines, but it’s still small and weak. Not worth suiting up for.
Wednesday the 16th — winds go cross-on, and it’s choppy. Sizes are 0.7m to 0.8m, but it’s lumpy junk. Thursday the 17th jumps to 1.8m to 2.0m, but the period is only 7 seconds, so it’s windswell, short and crumbly. The energy is moderate (376 to 458), but the wind is fresh cross-onshore and lumpy. This setup is more for kites than surfboards — it’s a mess.
Friday the 18th keeps the trend: 1.7m to 1.9m, cross-on, and lumpy. The morning period is still 7 seconds, and the afternoon sees a jump to 16 seconds with energy up at 2186, but the wind stays cross-on, and it’s a jumbled, choppy mess. You’re fighting the whole session.
Saturday the 19th — here’s where the swell pumps, but it’s too much. We’re talking 3.0m from the southeast, 13-second period, and strong energy (3580 in the morning). Winds are light and favorable, but that size is way too big for this break. This is expert-only — if you’re not comfortable in serious conditions, stay on the beach. The wave comment is clear: too big for this spot. I’d be very selective here.
Sunday the 20th — swell drops to 2.4m in the morning, but it’s onshore and messy, period back to 10 seconds. The afternoon is 1.8m from the south, 13-second period, but the tide is questionable and the wind is cross-on. Energy is strong (1667 to 1736), but quality is poor. Marginal at best.
Monday the 21st — 1.7m to 1.8m from the south, 12 to 13 seconds, but cross-on winds and choppy conditions. You’re getting waves, but you’re also getting pushed around. Not a standout day.
Tuesday the 22nd — this is your day. Morning: 1.7m from the south, 13-second period, light offshore wind, and clean. Energy is solid at 1219. Afternoon: 2.0m from the south, 14-second period, gentle offshore, and clean lines. This is excellent surf for experienced surfers — proper groundswell, good direction, and the wind is right. The best on offer, no doubt.
Wednesday the 23rd — morning is still good: 1.9m from the northeast, 11-second period, offshore, and clean (energy 1315). But the afternoon goes bad — cross-on winds at 35 km/h and lumpy. If you’re going, make it a dawn patrol.
Thursday the 24th — 1.3m, but fresh cross-onshore winds and lumpy. Poor. Friday the 25th — 1.1m, morning is cross-on and messy, afternoon is marginal. Saturday the 26th — small, 0.8m from the SSE, light offshore in the morning, but it’s ordinary, barely surfable. The afternoon fades.
Sunday the 27th — cross-on junk again, 0.7m to 1.7m, with the period dropping to 6 seconds in the afternoon. That’s pure windswell. Monday the 28th — 1.1m to 1.2m, cross-on, lumpy, poor. Tuesday the 29th — 1.6m from the ESE, onshore, fresh, and lumpy. Nothing to write home about.
So, the short version: the first week is mostly a washout. Your standout

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