The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking at Narrabeen-South over the next couple of weeks.

We’ve got a solid run of surf coming through, starting Friday the 24th of July. The early call is a clean, moderate S swell around 6 ft with a 10-second period and a light SW offshore breeze. The combined energy is moderate (553), and it’s going to be a ripper morning. This is a very consistent spot, exposed to the S swell, and with the wind swinging offshore, it’ll be well-shaped. Keep in mind, crowds are frequent here, so get in early. The water temp is about average for this time of year, nothing unusual.

Saturday the 25th holds. The morning has a similar 6 ft S swell but with a cross-offshore breeze, keeping things clean. The standout is Saturday afternoon—the swell drops slightly to 4 ft, but the wind goes glassy, NNE at only 3 mph. That’s a rare treat. The sets will be lined up from the S, with a combined energy of 360 (moderate), and it’ll be a dream session for those who like it smooth.

Sunday the 26th is still workable in the morning with a 6 ft S swell and a cross-offshore breeze, but the energy is moderate (749). The afternoon gets a bit bumpy with a cross-shore wind, so it’s more of a dawn patrol day.

Monday the 27th drops to a 4 ft S swell in the morning, clean with a light offshore breeze. It’s a smaller day, but the combined energy is 210 (weak), so it’s a good option for a longboard or a fun cruisy session.

From Tuesday the 28th through to Wednesday the 29th, the surf goes flat. Swell heights drop to 1.0 ft to 2 ft with very weak energy (as low as 53). There’s a 18-second period pulse on Wednesday morning, but with only 1.0 ft, it’s just a ripple. Not worth paddling out for.

Thursday the 30th brings a return of energy. The morning has a 3 ft S swell with a 13-second period, combined energy of 409 (moderate), and clean cross-offshore winds. The afternoon is the real standout here: 3 ft S swell, 12-second period, 549 combined energy (moderate), and glassy conditions. That’s a sweet, clean afternoon window.

Friday the 31st is a solid morning with a 4 ft S swell, 11-second period, and a light cross-offshore breeze. Combined energy is 447 (moderate). The afternoon gets a bit messy with a cross-shore wind, so the morning is your pick.

The first week of August sees a mix. Saturday the 1st and Sunday the 2nd are small, with 3 ft to 3 ft swells, but the wind is onshore or cross-onshore, killing the quality. The combined energy is weak to moderate (216 to 249). Not much to get excited about.

Monday the 3rd has a 5 ft ENE swell with a short 8-second period, but a clean offshore SW wind in the morning. Combined energy is 254 (moderate). The afternoon gets a strong S wind, so stick to the early session.

Tuesday the 4th and Wednesday the 5th see a jump in size: 6 ft to 7 ft SSE swells with a short 7-second period. The combined energy jumps to 629 and 637 (moderate), but the wind is cross-shore or onshore, creating chop. These are more for the experienced crew, and the short period will make them jerky.

Thursday the 6th is the big standout of the second week. A 8 ft SSE swell with an 8-second period, combined energy of 860 (moderate), and glassy conditions in the morning. That’s a big, clean, powerful swell. The size means it’s for experts only, but the wind will be perfect. Get on it early.

Friday the 7th and Saturday the 8th are not great. Friday has a 6 ft ENE swell with onshore wind, and Saturday the 8th has a massive 13 ft ENE swell with a 12-second period and combined energy of 4724 (strong). That’s way too big for this break, and the wind is cross-onshore and choppy. Only the most experienced chargers should even look at it, and even then, it’ll be a mess.

The best bet: The glassy Saturday afternoon (25th) and the clean Thursday afternoon (30th) are the top picks. For the bigger wave crew, the glassy Thursday morning (6th of August) is a standout.

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.
