The Lowdown

G’day, I’m Rusty, and I’ve been staring at the charts for this stretch. There’s a heap of swell coming down the pipeline, but it’s going to be a wild ride, especially for experienced surfers only. The first good window is Thursday morning, 27th August, and it’s a solid kick-off.

Thursday morning, 27th August – Johanna is the only spot on the cards, and it’s a classic. The water’s sitting at 57.2°, which is pretty much normal for this time of year, so no surprises there. We’ve got a clean 4.3ft swell from the WSW, with a solid 12-second period, and a light NW breeze keeping it cross-off. The energy is pumping with a combined reading of 1020, which is moderate wave energy. The surf is clean and excellent for experienced surfers, but it’s not a beginner wave. Expect crowds, as it’s often busy here.

Thursday afternoon – The swell bumps up to 4.9ft, but the wind swings to a cross-on W breeze, and it gets a bit choppy. Not the pick of the day.

Friday morning, 28th August – Things get serious. The swell jumps to 11.5ft from the WSW, and the period is a long 17 seconds (a proper groundswell). The energy is strong (7599). The wind is light cross-on, so it’s a bit textured, but the size is for experts only. This is getting too big for intermediates.

Friday afternoon – Still 11.5ft, but the period drops to 16 seconds. The wind stays cross-on, and it’s a bit messy. Big and grunty.

Saturday, 29th August – Swell drops to 8.2ft, but the wind is a cross-on W breeze, 9-12 mph. The energy is still moderate (2948). It’s a bit lumpy and not the best quality.

Sunday, 30th August – Back up to 9.8ft from the SW, with a 13-second period. Wind is cross-on again. The energy is strong (2863). It’s marginal, but there’s size.

Monday morning, 31st August – Now this is a standout. The swell is 11.5ft from the SW with a 15-second period, and the wind is a light NW cross-off. The energy is very strong (5726). The surf is clean and exceptional for experts. This is the best on offer in the first week. No crowds mentioned, but it’s a well-known spot.

Monday afternoon – Swell holds at 11.5ft, period 17 seconds, but the wind swings cross-on. Still big, but less clean.

Tuesday, 1st September – Morning has a 9.8ft SW swell with a 16-second period, and a strong NNW breeze at 22 mph, but it’s cross-off, so it’s clean. The energy is strong (3827). The afternoon turns to cross-shore wind and gets lumpy. Not great.

Wednesday, 2nd September – Swell pumps to 11.5-13.1ft from the WSW, but the wind is moderate to fresh cross-shore, creating a lumpy cross-chop. Big and messy.

Thursday, 3rd September – Morning is a standout. The swell is 14.8ft from the WSW, 13-second period, with a moderate NW cross-off breeze. The energy is very strong (13312). The surf is clean, but this is strictly for experts. The afternoon is similar but with rain showers.

Friday, 4th September – Huge day. The swell hits 19.7ft from the WSW, 14-second period, and the energy is massive (15554). The wind is cross-shore. It’s too big for this break, only for the most experienced. The afternoon is similar.

Saturday, 5th September – Swell drops to 16.4-18.0ft, but the wind is a strong cross-on, making it poor and lumpy. Not worth it.

Sunday, 6th September – The swell is 19.7-21.3ft, with a strong breeze up to 28 mph. The morning is a mess. The afternoon is better, but still lumpy.

Monday, 7th September – Another huge day. 21.3ft from the SW, 16-second period, with a moderate NW cross-off in the morning. Clean and massive, but it’s too big for the break. The energy is off the charts (20051).

Tuesday, 8th September – Swell hits 19.7-26.2ft, onshore winds, poor conditions.

Wednesday, 9th September – Morning has a 21.3ft SW swell with a light E cross-off, clean and massive, but too big. The afternoon drops to 13.1ft

Information about the Johanna Surf forecast

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