Table - best surf conditions forecast for Seaside Reef over the next 16 days.
The Lowdown
Alright, let’s break this down.
This stretch for Seaside Reef is a total bust. For the whole period, we’re looking at poor surf conditions, with the swell barely getting to 2 ft at best for days. The wind is almost always blowing onshore or cross-onshore from the WSW or SW, which is the kiss of death for this spot. The water is 76°, which is way warmer than usual for this time of year, but that doesn’t help the waves.
Starting on Saturday afternoon, the surf is just 2 ft from the SSW with a 14-second period and a weak combined wave energy of 278. It’s all poor. That same story drags through Sunday and Monday, with the swell dropping to 1 ft to 2 ft and the energy slipping between 129 and 207. Wind stays onshore, surf is poor.
Tuesday through Thursday of next week – still nothing. Morning swells are 2 ft to 2 ft, afternoons similar. The energy is low, between 144 and 230, and the wind keeps blowing wrong. It’s all small and choppy.
The end of the first week and into the second week sees a slight lift. From Friday the 7th through Tuesday the 11th, we get some swells around 2 ft to 3 ft from the SSW, with periods sometimes up to 19 seconds. The combined wave energy climbs into the moderate range – 447 on Friday morning and 499 on Saturday afternoon. But the wind stays cross-onshore and the forecast is still “poor surf conditions.” The longer 19-second period means those swells have lots of energy but they’ll break straight across the reef, and the chop will kill any shape.
The one day that stands a tiny chance is Saturday the 15th morning. That’s when the swell hits near 4 ft from the SW with a 16-second period, and the combined wave energy peaks at 658 – the strongest of the whole outlook. But the wind is onshore, and the forecast only calls it “marginal surf forecast or questionable tide conditions.” It’s the best on offer by a long shot, but it’s still not clean.
For the rest of the 16 days, it’s a desert. Gap after gap of poor conditions. For this area, a blank run like this is pretty normal, so don’t get too down – things can turn around.

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