Derrs

Derrs is an exposed reef break in the Perth northern coastal corridor, known for dependable surfing that can work through the year. The wave travels over a sand-and-reef/sand-and-rock bottom, producing both right and left options, with rides that can reach roughly 50 to 150 meters when conditions are aligned. Best performance is tied to a southwest swell meeting lighter offshore winds from the east to northeast. The spot is commonly described as working around mid tide, especially when the tide is falling, and it tends to be more forgiving when winds stay offshore rather than switching to stronger onshore/sea-breeze conditions. Seasonally, winter is associated with the most consistent swell (with June highlighted as a best month in spot guidance), while summer mornings are often cleaner before the afternoon sea-breeze develops. In the warmer months, strong afternoon sea breezes (the local Fremantle Doctor pattern) are common and can quickly increase chop. Safety planning is important here: hazards include rocks and sharks, with additional risks from submerged reef sections and rips depending on swell size. There are no lifeguards at the spot, so surfers should arrive with appropriate gear (including a wetsuit, leash, and boots if needed) and plan entry/exit around tide and wind timing—checking the conditions early before the sea breeze strengthens.
