The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' at Blackies.
Honestly, mate, it’s a tough stretch ahead. We’ve got a long, slow run of onshore and cross-onshore winds that are just gonna chop up whatever small swell tries to roll in. The water is 71.1°, which feels much warmer than usual for this time—kinda nice if you're just floating around, but doesn't help the waves.
Looking at the whole 16-day window, there’s no standout day. Tuesday the 11th kicks off with a small 1.6ft SSW swell, but that cross-on wind from the WSW at 6 mph is already putting a poor surface on it. That same story just repeats day after day. There's a bit of a bump in combined energy on Friday the 14th morning (403) with a clean offshore wind, but the swell is only 1.6ft and the period is a long 19 seconds—that kind of groundswell tends to run straight down the beach and won't shape up well here. It’s really marginal.
Through the first week, the swell doesn’t get above 3.3ft on Saturday afternoon, but the cross-on wind kills it. Then from mid-week the second week the swell drops right off, barely 1.3ft to 2.3ft. The energy values climb back up around 398 to 578 on the 25th and 26th, but again the wind is cross-on from the west, dirtying the surface. These are not waves you paddle for unless you're really desperate to wet the board.
The only slight glimmer is on the Friday 14th morning—offshore wind, long period, and combined energy of 403—but with the break being inconsistent and the swell small, it’s a gamble. If the tide lines up and you're local, you might snag a couple. Otherwise, honestly, it's a stretch of poor to marginal conditions. For the majority of this forecast, you’re better off doing something else.
Stay salty.

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