The Lowdown
Alright, how's it going? It’s a quiet one coming up at Porsmilin, a proper dry spell for the first good stretch. The ocean just has nothing to offer for about a week or more.
We kick off on Tuesday the 4th of August. It looks clear, but the swell is a messy 4 ft from the WSW with a short 8-second period. With a strong 12 mph onshore wind from the SW, the conditions are poor, flat out. That carries right through to Wednesday. By Wednesday afternoon, the swell pushes up to 5 ft from the W (261 moderate energy), and the wind goes cross-offshore from the NW, which cleans it up, but it is still only a marginal call.
Thursday the 6th is a nothing day. You get a 4 ft wave from the NW with the period dropping to 7 seconds, the energy is low at 124. It’s surfable, but just very, very ordinary.
Then we hit a total flat spell. From Friday the 7th of August through to Wednesday the 12th, the swell just vanishes. You’re looking at knee-high dribble, tiny 1.0 ft to 2 ft waves. A few glassy mornings like Friday and Wednesday the 12th, but with zero swell, it’s a total pond. No decent waves anywhere.
A little pulse of energy shows up around the 14th of August. Friday morning has 4 ft from the W with a shocking 6-second period and a cross-offshore wind, just ordinary. The afternoon gets a bit more size, hitting 6 ft (310 moderate energy), but with that super short period, it’s messy and for the more experienced only. The best shot in this whole outlook, and it's a tiny window, looks like the morning of Sunday the 16th of August. A fun size 3 ft from the W with just a light 6 mph cross-shore breeze. It is small and clean. That's the pick if you're desperate for a knee-to-waist high wave.
It’s a tough run. I'd leave the boards in the truck for a week and a half, keep an eye on that second weekend. If you’re a kite surfer, that Wednesday the 5th afternoon with 5 ft and a 12 mph cross-off wind might be interesting, but for a paddle surfer, it’s a no-go.

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