The Lowdown

Alright, let’s break it down. We’re talking about Johanna, a classic exposed beach and point break that fires on a good southerly. Water temp is about 58°, which is pretty normal for this time of year.

First real call is Friday morning, July 31st. Clean 7ft SW groundswell with a 12-second period. The wind is light and cross-offshore from the NW, so it’s glassy. The combined energy is strong at 1498. This is excellent for experienced surfers, but a bit much for beginners. Johanna is consistent, so it’s worth a look. Crowds are often around, so expect company.

Now, Saturday, August 1st, is the standout. Saturday morning shows 8ft SW groundswell with a very long 17-second period. That’s a proper groundswell. The wind is light from the N, cross-off, and clean. The energy is already pumping at 3597. Then Saturday afternoon winds up: 10ft SW, still 17 seconds, clean cross-off from the NNW. The combined energy hits 5241. This is exceptional, expert-level surf. The long period will make it break a bit straight at the beach, but the point section should handle it beautifully. This is the best on offer, no question.

Sunday, August 2nd, stays solid with 10ft SW, 16-second period, but the wind picks up to 12 mph. It’s still cross-off, so it’s clean, but the energy is still strong at 4342. The tide or something might make it a bit marginal. Still a good day for the experienced surfer.

Monday, August 3rd, sees a drop to 7ft SW with a 14-second period in the morning. Clean, cross-off wind from the NW. It’s a good call for experienced surfers. The afternoon gets messy with a 13ft WSW swell but cross-on wind, so it’s not ideal.

Tuesday, August 4th, is a write-off. Cross-on wind, choppy, and the afternoon turns into poor surf conditions. Same for Wednesday, August 5th, with smaller, choppy surf.

Thursday, August 6th, offers a reprieve. The morning shows 6ft WSW groundswell with a very long 16-second period. Clean cross-off from the NW. The energy is moderate at 1761. That’s a nice, clean session for those who know the spot.

Friday, August 7th, is another strong call. Friday morning: 10ft WSW, 16-second period, next to no wind, clean. Energy is 4224. Friday afternoon: 8ft WSW, 17-second period, cross-off from the ENE, clean. Energy is 4425. Excellent for experts.

Saturday, August 8th, is a bit of a mixed bag. The swell is 7-7ft, long period, but the wind is gusting to 19 mph. It’s clean, but fresh. The energy is solid but lower. Definitely a day for the brave.

Sunday, August 9th, is massive. 16ft W swell, 14-second period, with offshore wind from the NNE at 12 mph. The energy is through the roof at 15886. The file says it’s too big for this break. This is for experts only, and even then, it’s a serious call. The afternoon is a bit smaller but still huge.

Monday, August 10th, is even bigger. 18ft WSW, 18-second period, wind from the NNW at 19 mph. Energy is 17324. Again, too big for this break. Only for the most experienced.

The rest of the week from Tuesday, August 11th, through Saturday, August 15th, is a mix of massive, messy, or onshore conditions. Swells stay over 8ft most of the time, with periods of strong cross-on wind and choppy surf. There are a few moments of clean, big swell, but it’s generally for experts only, with the wind and power making it a tough paddle.

The bottom line: The best windows are Saturday August 1st and Friday August 7th. If you’re an expert, there’s plenty of power on offer, but the long period swells will make the beach section tricky. Stick to the point for the best shape.

Rusty.

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.
