Seaford sits on Gulf St Vincent, roughly 35 kilometres south of the Adelaide CBD. Its weather is moderated by the sea: summer maxima typically sit 2–3°C lower than inland suburbs such as Noarlunga. Winter minima hover around 8°C, with morning cloud clearing by midday on roughly two-thirds of days. The prevailing south-westerly swell brings afternoon sea breezes from November through March, often dropping the temperature by 4–6°C in under an hour.
