Onrus Surf Forecast and Surf Report

G’day, Rusty here. Let’s take a look at what’s brewing for the next couple weeks at Onrus (South Africa). We got a mixed bag, with some proper gems and some days that are just plain angry.

First up, Tuesday the 14th is a slow start. Waves are small and ordinary – 2ft from the west, low energy, and a cross-off breeze. Water temp’s 59°F, just about average for this time of year. Not worth paddling out for the morning or afternoon.

But Wednesday the 15th morning is where it gets real. A clean 4ft groundswell from the SW, 17-second period, energy swinging strong. With a light offshore breeze, it’s lined up and beautiful for an intermediate. The afternoon bumps to 7ft, period 16 seconds – still excellent for experienced surfers. The morning is the standout here.

Thursday the 16th is another good one: morning sees 8ft swells from the SW, 13-second period, glassy – that’s expert territory though. The afternoon is 7ft and clean. That morning glass is the pick.

Friday the 17th is a washout. Cross-onshore winds, lumpy, messy – skip it.

Saturday the 18th bounces back nicely. Smaller in the morning (3ft, 14-second period), cross-off, clean. The afternoon is the real treat: 5ft, 13-second period, glassy. Clean, fun, and worth the wait for the sets at this inconsistent reef.

Sunday the 19th morning is another highlight: 6ft from the SW, 12-second period, glassy, clean. But the afternoon gets a strong onshore wind, making it marginal.

Monday the 20th is messy again. Some waves around 6-6ft, but cross-on winds ruin the shape.

Tuesday the 21st brings a massive swell – 10ft from the SW, 15-second period, energy huge. Offshore wind at 15 mph keeps it clean, but it’s too big for this reef. Expert-only, borderline dangerous. Wednesday the 22nd is even bigger – 12ft, near-gale offshore winds. Not for paddling.

From Thursday the 23rd to Friday the 24th, waves settle to 6-7ft with mostly clean or light winds. Surfable, but nothing epic.

Saturday the 25th morning is a nice little surprise: 3ft from the SW with a massive 19-second period. That’s very long-period groundswell, and with light cross-off winds, it’ll be beautiful and lined up, though it might break a little too straight. The afternoon jumps to 8ft with a 16-second period, but has a cross-shore wind.

Sunday the 26th and Monday the 27th are dominated by strong onshore winds and lumpy surf. The 27th in particular has fresh cross-onshore winds of 18-22 mph, ruining the 4-6ft swell. That’s kite territory.

Tuesday the 28th sees a return to clean conditions with offshore wind and 6ft swell, 14-second period. Wednesday the 29th morning has a fresh offshore and 7ft from the west. The afternoon brings another massive pulse: 10ft, 11-second period, energy through the roof – but again, too big.

The real standouts are Wednesday the 15th and Thursday the 16th. Clean, long-period SW groundswell, glassy or offshore. Sunday the 19th morning and Saturday the 25th morning are also worth marking. Second week is a mix of too-big and blown-out, but there are clean windows.

Rusty.
