The Lowdown

G'day, Rusty here. Looks like we've got a solid run of swell on the way for Johannas, but it's gonna take a bit of patience to get the real gems. The water's sitting at 57°, which is dead on average for this time of year—nothing to write home about, but you won't be needing a steamer just yet.

The first few days are a bit of a tease. Wednesday the 19th kicks off with a 4ft WSW groundswell, period a juicy 15 seconds, but that cross-off wind from the NNW at 12 mph is just enough to keep it from being perfect. The energy's weak (702), so it's more of a warm-up paddle than a standout.

Thursday the 20th builds quickly—by the afternoon we're looking at 7ft from the west at 13 seconds, with the combined energy jumping to 2047. Still, that cross-off wind from the NW at 12 mph means it's not really firing. Friday the 21st gets bigger, with 10ft WSW groundswell (15 seconds) in the morning, but the wind swings cross-shore from the WNW at 12 mph, putting a bit of a chop on the face. Energy's pumping at 5559, but the quality's not there yet.

Saturday the 22nd is a write-off—13ft WSW swell with a 16-second period, but the wind's cross-on from the west at 12 mph, making it a choppy mess. That's kite-surfing territory, not paddle surfing. The energy's massive (7610), but you won't want to be out there.

Sunday the 23rd brings a reprieve. Morning sees 12ft from the SW at 14 seconds, with a cross-off breeze from the NW at 9 mph. The energy's still strong at 5510, and the wave comment says marginal, but it's clean. Not a standout, but a solid session.

Now, here's where it gets interesting. The real standout is Friday the 28th of August. Come afternoon, the wind drops to glassy from the south at just 3 mph, and the swell is a solid 16ft from the SW at 16 seconds. The combined energy is off the charts at 11570. This is big, powerful groundswell—expert only, with that much power. The long period will make it a bit walled at a beach break, but Johannas being a beach and point setup means the point should handle it beautifully. Clean, glassy, and pumping. That's the one to circle.

Saturday the 29th follows up with a 16ft SSW swell in the morning, 13-second period, and a light offshore from the ENE at 3 mph. Energy's at 8466, and it's clean. Another huge day for the experienced crew.

After that, things settle into a nice groove. Sunday the 30th through Tuesday the 1st of September sees 8ft to 12ft SW groundswell, with periods up to 16 seconds, and light offshore winds from the ENE and NE. The energy drops to moderate levels (around 1650 to 3679), but it's clean and consistent. Great for intermediate surfers. Wednesday the 2nd and Thursday the 3rd of September offer smaller waves—4ft to 5ft—with glassy to light offshore conditions. Perfect for a longboard or a fun summer session.

So, bottom line: the first week is a mixed bag with some decent but not epic days. The absolute standout is Friday the 28th of August—glassy, 16ft SW groundswell, and all that power. Get on it if you're experienced. The second week offers cleaner, smaller conditions that are more accessible. Don't sleep on the 28th, though.

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.
