Onrus Surf Forecast and Surf Report

Alright, let's get into this.

This forecast for Onrus is a bit of a slow burner, but there are some clear windows of clean swell if you're patient and pick your moments. The first few days are pretty ordinary, but once the wind plays ball, there’s some proper quality to be had.

Right now, the start of the period is a write-off. That south-west swell is building on Sunday the 6th, but with a strong cross-onshore breeze out of the east at 19 mph, it's lumpy and choppy. The water’s sitting at 58°F, which is a bit colder than normal for this time of year, so you’ll want a decent steamer.

The first real opportunity comes Monday the 7th. Both morning and afternoon sessions are looking glassy with offshore wind from the northwest and then swinging light south-southwest. Swell drops slightly from 6ft to 6ft but stays in that solid intermediate range with a nice 14 to 13-second period. This is a classic groundswell setup for the reef here, and the energy is strong. This is your standout window for experienced surfers. The break can be inconsistent, so you might wait a bit between sets, but when they come, it’ll be worth it.

Tuesday the 8th is much smaller, dropping to under 3ft, but it’s glassy again. Good for a longboard or a fun foiling session if you have one. Not really a standout.

Wednesday the 9th is a write-off with a light cross-onshore creep and poor quality.

Now here’s the one that has my attention but comes with a health warning: Thursday the 10th. The morning session sees a massive pulse of 10ft south-west swell with a 16-second period. The energy is extreme. Problem is, the wind is cross-onshore and the forecast notes it may be too big for this break. Unless you’re a very experienced surfer comfortable with heavy, powerful reef waves, give this a miss. It might look epic, but it’s more likely dangerous and messy.

Friday the 11th through Saturday the 12th is a block of poor conditions with onshore winds and lumpy seas. Nothing doing.

Sunday the 13th is a return to form. Offshore wind from the northwest, 16 to 19 mph, cleaning up a solid 6ft to 5ft south-west groundswell. Excellent conditions for experienced surfers. The moderate offshore will hold the waves open and clean. This is another standout window.

Monday the 14th morning looks great with a moderate offshore, 4ft swell and clean lines. Monday afternoon gets weird—short period windswell at 7 seconds and 8ft from the west. That’s more of a messy, blown-out offering. Might be better for a kite than a paddle.

Tuesday the 15th morning sees another big 10ft west-southwest swell with long period, but again, flagged as possibly too big for the break. The afternoon improves with offshore wind and 8ft, which should be manageable for the experienced crew.

From Wednesday the 16th through to Thursday the 17th, it’s onshore and messy again. Not worth the drive.

Friday the 18th is a mixed bag with a cross-shore breeze and a 8ft south-east swell. It's marginal at best.

Now the real treat is the final weekend: Saturday the 19th and Sunday the 20th. Clean conditions with cross-offshore or light offshore wind, solid 6ft to 8ft south-west swell, and long-period energy in the 13 to 16-second range. This is proper groundswell and should handle the reef beautifully. Energy is strong. These are your best bets for a clean, powerful session.

Monday the 21st is marginal again with light onshore creep. The period fades a bit.

Overall, the standout sessions are Monday the 7th, Sunday the 13th, and the weekend of the 19th and 20th. Get on it when the wind is offshore.

Rusty.
