Guilderton Rivermouth

Guilderton Rivermouth is a surf spot at the mouth of the Moore River in Guilderton, Western Australia, about an hour north of Perth.

Spot description

• Type: River mouth beachbreak / sandbar setup
• Wave character: Can be mushy and playful on smaller days, but it can also produce fast, punchy peaks when the sandbanks line up.
• Best conditions: Usually works best with clean offshore winds and a solid swell pushing into the sandbars.
• Direction: Often handles west to southwest swell well, with the river mouth helping shape the banks.
• Tide: Can change a lot with tide; some sections work better mid to low tide, depending on the sand movement.
• Crowds: Can get busy on decent swell, especially because it’s a popular weekend destination near Perth.

What it’s like to surf

• Good for intermediate surfers looking for fun beachbreak waves.
• Can be forgiving on smaller days, but on bigger swells it may become bumpy and powerful.
• Sandbanks shift often, so the quality can vary from day to day and season to season.

Hazards / notes

• Strong currents can form around the river mouth.
• Shifting sandbars and channels can make takeoff zones inconsistent.
• After storms or big swells, conditions can change quickly.

Best for

• Shortboards in cleaner, steeper conditions
• Funboard/soft-top sessions on smaller, softer waves
• Surfers wanting a close-to-Perth beachbreak option with some variety
