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.
