Listed as a safe beach on the Beach Safe website with a 3/10 rating (least hazardous), it is good for younger children and those wanting a swim with only very small waves. The water is reasonably shallow, but, obviously, does get deeper once you go out towards the end of the pier. There are a couple of sand banks with run parallel to the beach. Before the first one is the best place for younger children or those who aren't frequent beach goers.
The Seaford Surf Lifsaving Club is located next to the toilets and a cafe with great views. The cafe is small and has limited food options, which army cheap, but the view and location makes up for it. Founded in 1919, the club is now housed in a modern building. They patrol the beach at certain times during the warmer months. For more details see the website.
The pier is a popular fishing spot. Stretching out from near the life saving club building, it isn't really long, but is a decent size for a short stroll and plenty big enough to fish off.
There is sealed carpark available right next to the beach, although there are limited spaces and it is ticketed. There are clean, reasonably new public toilets right next to the carpark and the beach, as well as a wheelchair ramp to access the beach. Some other shops, including a small supermarket, are only across the road, as well.
