The Lowdown

G’day, Rusty here. I’ve taken a look at Seaford Reef over the next couple of weeks, and I’ve got to be honest – it’s a rough outlook. This little reef is a sheltered, beginner-friendly spot that’s usually inconsistent, and the forecast is giving us almost nothing. There are long dry spells where there’s no surf worth paddling for, and even when we get a bump, the conditions are poor.

The first bit of size doesn’t show up until Saturday the 14th of September. On Monday morning the 14th, we see a 3ft west swell, but it’s a short 4-second windswell, and the wind is cross-onshore – choppy and ugly. That afternoon, the swell builds to 7ft from the west, period up to 6 seconds, with a combined energy of 318 (moderate). But again, the wind is cross-shore and messy. That’s too big for beginners and, with the short period and lumpy wind, it’s more of a kite-surfing day than a clean surf session.

Tuesday the 15th of September offers 5ft from the west-southwest in the morning, period 6 seconds and energy at 190 (moderate). A fresh 19 mph south-southeast cross-offshore wind will keep the surface clean, but the swell is weak and short. Still poor surf conditions. The afternoon fades fast.

After that, it’s back to tiny stuff – 1ft or less – for the rest of the run. There’s a glassy moment on Friday afternoon the 18th of September with a tiny 3ft south-southwest swell and a light offshore breeze, but the period is only 5 seconds and the energy is just 29 (weak). It’ll be clean, but you’ll be lucky to catch anything rideable.

There is no standout here. The best you could do is the glassy Friday arvo the 18th if you want a tiny, clean knee-high wave. Otherwise, it’s a long, flat, poor stretch. The water temp is about 58°, which is average for this time of year. Don’t get your hopes up – this forecast is a dud.

Rusty.

Information about the Seaford Reef Surf forecast

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