Koi ponds and water features in Perth

Perth's strong outdoor lifestyle culture and many large suburban properties make it a growing market for koi ponds and water features. Several specialist pond builders operate throughout the metro area.

Perth climate considerations for koi ponds

Perth's Mediterranean climate — hot dry summers, mild wet winters — creates unique pond challenges. Evaporation rates are extremely high in summer, requiring regular top-up. Water temperatures can reach 30°C+ in summer, placing significant stress on fish and filtration systems. The good news: winters are mild and koi remain active year-round, unlike in Melbourne or Canberra.

Local tip: Perth pond owners should install an automatic top-up valve connected to a water supply to compensate for evaporation — losing 2–3cm of water depth per week in summer is common without top-up. Shade cloth or strategic planting to reduce afternoon sun exposure is also valuable in Perth's intense summer heat.
