The Lowdown
Alright, let’s talk what’s coming. There’s nothing right now, but it’s all ahead of us.
The first real window hits Saturday morning, 15th August. We’ve got a solid 13-foot SW groundswell, and it’s dead glassy—no wind at all. That’s going to make Johanna’s famous lines perfect. Water temp is about 57°, which is average for the season. This is a standout for experts only.
Saturday afternoon gets onshore, but still 13-foot. Sunday is smaller and gets choppy with a southeast wind.
Monday morning, 17th August, is clean with cross-off winds and an 8-foot WSW swell with a 16-second period. That long period will wrap into the point real nice. Combined energy is moderate (2908). Tuesday morning, 18th August, is another gem: 7-foot SW, glassy offshore northeast winds, and a 14-second period (1329 energy). Clean lines.
Wednesday 19th goes downhill with strong north winds blowing at 22 mph offshore, but it’s too gusty. Swell drops. Thursday 20th goes glassy again, but only 4-foot of WSW with a very long 18-second period (1462 energy)—a bit fat for the beach, but the point might still work.
The 21st and 22nd are poor with strong southwest winds and lumpy chop. Sunday 23rd has 11-foot of WSW but cross-onshore winds.
Then Monday, 24th August, it’s massive: 18-foot SW groundswell, glassy conditions, and a 16 to 17-second period. Way too big for almost everyone—experts only. Energy is extreme (16594+). Tuesday 25th cleans up with 10-foot SW and clean cross-off winds (3709 energy). Wednesday 26th fades with strong north winds.
From Thursday 27th onward, it’s cross-onshore messy surf through the 29th with small 5-foot SW.
Best bets? Saturday 15th morning is the clear winner: big, glassy, and clean. Monday 17th and Tuesday 18th are very good for experienced surfers. The 24th is a monster, but only for the brave. Crowds at Johanna are likely on the good days—it’s a popular spot.

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.
