Fourth Mile Beach

Fourth Mile Beach (also known as Twilight Beach 1) is a wide sandy beach near Esperance with crystal-clear Southern Ocean water and small-to-medium wave conditions. It has a beach-break character for surfing, but rocks (including rocks at either end and scattered submerged rocks) are a recurring hazard for board sports at the waterline. For wind sports, the spot is best known for kitesurfing in ESE, SE, and SSE winds. Multiple sources agree on the same summer-focused month pattern (January–March and also September–December) and describe the summer afternoons as the most dependable on-water window, consistent with a sea-breeze driven thermal pattern. Typical winds are described as roughly in the 15–25 knot range, with light gustiness reported. Surf conditions are described as generally manageable (small-to-medium to medium-wave beach break), with mushy wave shape and moderate wave power. Guidance also notes that southerly winds can chop the surface and that, on bigger swell, the waves may close out when they exceed around 3 meters. Safety planning is important here: rocks are specifically called out as hazards, sharks are mentioned as a risk, and moderate rip currents can occur near rock formations. Also note local guidance that Esperance can swing from warm midday conditions to a much colder evening quickly, so weatherproofing and a conservative plan for dusk are recommended.
