The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
Straight up, this is a bleak run for Seaford Reef. We’re looking at a solid 16-day window, but the first week and a half is pretty much a write-off for a proper paddle session. The water’s sitting at 58°F, about average for this time of year, nothing unusual there.
The first real flicker of something rideable doesn’t show up until Monday morning, the 27th of July. We’ll see a long-period groundswell pushing in from the WNW at 5ft, with a period of 6 seconds. The combined energy is moderate (155), and with a light cross-offshore breeze from the NNE, the surface will be clean. It’s surfable, but that short period means the waves will be a bit crumbly and unorganized. Not a total loss, but nothing to get the heart racing. The afternoon goes glassy, but the swell drops back to 3ft with low energy (74), so the morning is the only real look.
After that, it’s back to tiny, messy, or flat conditions for the rest of the week and into the start of August. There’s a pulse of windswell on Sunday the 2nd of August, with 4ft from the north, but the period is a poor 5 seconds and the cross-shore wind will keep it choppy. Not worth chasing.
Looking at the second week into early August, the swell completely flatlines from the 1st to the 5th, with energy readings of zero or single digits. The wind is mostly offshore or cross-off, but with no waves to work with, it’s a bust.
The one standout here is that Monday morning, 27th July. It’s not spectacular, but it’s the only window where the numbers line up for a clean, surfable wave. Everything else is a waiting game.
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.
