Table - best surf conditions forecast for Johanna over the next 16 days.


Alright, mate, Rusty here. Let’s have a proper look at what’s coming down the line for us at Johanna. This is a big, exposed beach and point setup that can handle some serious size, but we’ve got a wild ride ahead for the next couple of weeks. The water is sitting at 58.6°, which is about average for this time of year, so nothing out of the ordinary there.

The outlook kicks off on Sunday the 12th of July, and honestly, don't even bother paddling out. We’re looking at a massive 19.7ft swell from the WSW, but a strong W wind is making a mess of it with lumpy cross-chop. The combined swell energy is a thumping 10892, so there’s plenty of power, but it’s messy and dangerous.

Monday the 13th is the real standout in this whole forecast. The morning session is going to be something special. We’ve got a 21.3ft swell from the WSW with a long 15-second period, which brings incredible energy (20131). The wind is a clean cross-offshore from the NW, and the conditions will be clean. However, and this is a big however, this is way too big for anyone who isn’t a seasoned expert. At over 8.2ft, this is strictly for the big-wave crew. The afternoon stays big and clean, but a 23.0ft swell with 16-second period and strong cross-wind from the WNW makes it a no-go for safety.

Tuesday the 14th sees the swell dropping but the wind swings onshore from the W. It’s a write-off with poor, lumpy conditions all day. Wednesday the 15th is marginal and choppy with dropping swell.

Now, look to Thursday the 16th as the first real opportunity for skilled surfers. The swell has dropped to a manageable 11.5ft from the SW, but with a light NNW cross-offshore wind on the morning, things will be clean. The period is long at 14 seconds, so you’ll get some nice lines, but it’s a powerful wave for experienced surfers only.

Friday the 17th is another gem. The morning has a 11.5ft SW swell with a long 16-second period, and the wind is a light cross-offshore from the NNW. Clean waves, lots of energy (6288). This is a top pick for the week.

By Saturday the 18th, the swell drops to 8.2ft from the WSW, and by the afternoon we get flat calm, glassy conditions. This is a beautiful window for intermediate surfers who can handle a bit of size.

From Sunday the 19th through to Friday the 24th, the swell is mostly in the 4.9ft to 8.2ft range, with a run of clean conditions and generally light winds. The standout in this period is Friday the 24th afternoon. The swell picks up to 8.2ft from the SW with a very long 18-second period. The wind is glassy from the SE, and the combined energy jumps to 5160. This is an exceptional session for expert surfers as the long period groundswell will wrap beautifully around the point.

The second week closes with Saturday the 25th offering a 13.1ft WSW swell with clean cross-offshore winds in the morning. It’s big, but for the experts only. After that, the winds start to mess things up, and the surf becomes marginal and choppy into Sunday and Monday.

So, to sum it up: Monday the 13th morning is the heavy-hitter for the big-wave legends, but Friday the 17th morning and Friday the 24th afternoon are your best bets for clean, powerful waves that won’t try to kill you. Stay safe out there.

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.
