Climate

The world’s rainforests have been described as the ‘lungs of the Earth’ because of their high oxygen production. While the climate of the Great Bear Rainforest is temperate, its coastal setting produces more coniferous trees that generate more oxygen than other temperate rainforests. This rainforest has some of the world’s largest stores of carbon and ranks as one of the wettest non-tropical areas in the world with high rates of precipitation – mostly rain – making the forest very dense and green.

The Great Bear is cool in temperature given the abundance of tall trees, high canopies and limited sunlight reaching the forest floor. These conditions cause a biodiverse environment with slow decomposition processes where living or organic matter is transformed into inorganic matter, like soil.

Adopting an ecosystem-based management approach to forest management in the Great Bear Rainforest – a form of ‘lighter touch’ logging – will reduce carbon dioxide emissions and lower ecological risk to the rainforest environment. Such actions are intended to slow climate change.

  • Weather is temperate year-round.
  • June, July and August are the warmest months in the northern and coastal regions.
  • In the northern regions, summer highs reach 17°C and winter lows hit -2°C.
  • In the southern regions, average annual highs are 17.9°C in August with lows of 0°C in January.
  • Moderate winter snowfalls happen along the coast with colder temperatures and more snow at higher elevations.
  • An average of 6,650 mm of rain falls each year. Most rain occurs in the winter months.
  • Humid winds are caused by the warm ocean currents which cool as they move by the mountains.
  • The foggy air creates ‘fog drips’ that fall from the trees.
