The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming our way.

We’re just kicking off with a bit of a slow start, but don’t let that fool you. There’s some real firepower building later in the period. The first few days are a write-off for anything decent, but from Thursday the 30th, things start to get seriously interesting. There’s a solid window of clean, powerful surf, especially for the experienced crew.

Sunday 26 July is a scratch. The swell is there at 7 ft from the S, but the wind is all wrong, a cross-off that’s keeping things messy. The combined energy is moderate (938). Not worth paddling out for.

Monday 27 July morning cleans up a bit with a light W wind, but the swell drops to 4 ft from the S. Wave energy is weak (208). It’s surfable but nothing to write home about. The afternoon turns onshore and ugly.

Tuesday 28 July and Wednesday 29 July are flat and forgettable. The swell is tiny, barely a ripple. Save your energy.

Now, here’s where it gets good. Thursday 30 July is the standout. Thursday morning brings 7 ft S swell with a gentle WSW offshore wind. The combined energy jumps to moderate (699). But it’s Thursday afternoon that’s the real gem: 8 ft S swell, 11-second period, with a clean cross-off breeze. The energy is very strong (3101). This is excellent surf for experienced surfers. Narrabeen-South is exposed to the S, and this swell direction is spot on. The water temp is 64°, which is about average for this time of year.

Friday 31 July keeps the power going. Morning sees 8 ft S swell with a moderate SW offshore wind, energy is strong (2141). Another one for the advanced crew. The afternoon gets a bit wind-affected.

Saturday 1 August is still solid. Morning has 6 ft from the SSE with a gentle offshore SW wind, energy is moderate (645). Afternoon holds 5 ft SSE with a clean cross-off. Good, consistent waves for the weekend.

Sunday 2 August through Tuesday 4 August see the swell ease back. The winds are mostly onshore or cross-shore, and the quality drops. Not the best, but a few smaller waves might be rideable in the mornings if you’re desperate.

Wednesday 5 August is a bit of a wildcard. A small 2 ft SSW swell with an offshore SW wind, but the period is a short 5 seconds. Energy is weak (60). It’s surfable but ordinary.

Thursday 6 August brings a pulse back. Afternoon has 8 ft S swell with a cross-off breeze, energy is strong (1922). The score is decent, but it’s a bit on the messy side.

Friday 7 August is a mixed bag. Morning has 5 ft S swell with a cross wind, not ideal. The afternoon goes onshore.

Saturday 8 August is a monster, but it’s too big for this spot. 10 ft S swell in the morning with glassy conditions, and the energy is very strong (3422). The afternoon jumps to 13 ft S swell with a 13-second period, energy is very strong (8455). This is for experts only, and even then, it might be too much for Narrabeen-South. The wind is offshore in the afternoon, but the size is the main factor.

Sunday 9 August through Monday 10 August – the swell is still solid, but the winds are a problem. Onshore and cross-onshore winds chop things up. The energy is still there, but the quality is marginal.

So, the pick of the period is Thursday 30 July afternoon and Friday 31 July morning. Clean, powerful S swell at 8 ft, good winds, strong energy. That’s your best chance for a real session. The Saturday 8 August swell is huge but only for the brave and the very experienced. For the rest of us, that Thursday-Friday window is the one to circle.

Stay frothy.
Rusty.

Information about the Narrabeen-South Surf forecast

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