Perth, Western Australia Moonrise & Moonset Times

Perth, the world's most isolated major city, faces the Indian Ocean from the Swan Coastal Plain, and its westward orientation means moonset over the ocean is often as spectacular as moonrise over the Darling Scarp to the east. Today's moonrise is at 17:45 and moonset at 07:58. When the moon clears the jagged silhouette of the Darling Range it pours silvery light across the Swan River, turning the broad reach between South Perth and the CBD into a glittering runway of reflected brilliance, with the glass towers of Elizabeth Quay catching every shifting gleam.

Kings Park, perched on the escarpment above the river, provides an elevated grandstand where the full moon appears to hover between the city skyline and the dark line of the Helena Valley bushland, its amber glow deepening as it sinks toward the western horizon and the Indian Ocean. Cottesloe Beach, Perth's iconic sunset strip, reverses its role on full-moon nights when the moonset sends a final column of pale light across the water just before dawn, the groyne's dark outline cutting the reflection into parallel bands of silver and shadow. In the dry Southern Hemisphere winter, Perth's famously clear skies and low humidity create ideal conditions for lunar observation, and from Rottnest Island, eleven kilometres offshore, the moon rises above a perfectly flat eastern horizon with nothing but ocean behind it.

Tracking moonrise and moonset times assists evening sailors on the Swan River, helps photographers at the Blue Boat House in Crawley frame the moon between the boathouse roof and the water, and guides night walkers along the coastal path from Scarborough to Trigg. Perth's combination of river, ocean, and elevated parkland ensures the moon can be enjoyed from multiple perspectives within minutes, making it one of Australia's most versatile cities for moonwatching.
