Fraser Valley Farming Climate

Weather in the Fraser Valley is mild, especially compared to Ontario and the rest of Canada. Thanks to the nearby Pacific Ocean and Coast Mountains, we have warm summers, plenty of precipitation, and winters that rarely dip below zero Celsius – with long periods of little or no frost. In Surrey, for instance, the average summer temperature is 22 °C (72 °F), while the winter average is 5 °C (41 °F).

Fraser Valley rainfall averages:

  • Surrey: 152 cm/60 in.
  • Chilliwack: 158 cm/62 in.
  • Delta: 90 cm/35 in.
  • Abbotsford: 148 cm/58 in.
  • Langley: 140 cm/55 in.

Environment Canada issues regular weather forecasts for Vancouver (covering weather in Langley, Surrey and Delta), Chilliwack and Abbotsford. It also publishes alerts on storms and other extreme weather events.

Effects of Climate Change

Climate change is affecting farming regions worldwide. Over the coming years, Fraser Valley weather conditions are expected to follow global trends, with gradually increasing annual temperatures, growing degree-days (heat accumulation), longer frost-free seasons and increased winter and spring precipitation. Scientists also predict more frequent extreme weather events – windstorms, heavy rain, forest fires, hail, droughts and floods – and drier summer conditions for BC’s farming climate. The Province is helping farmers meet these challenges through its Climate Action Initiative.

Additionally, seasons are shifting. This can have a significant impact on production planning. For example, raspberry harvests used to start in early July, however, in the past two years, has ended by mid-June. Rainfall averages should be supplemented with monthly trends.

BC Agriculture & Food Climate Action Initiative

The Climate Action Initiative provides resources for farmers to adapt and respond to the challenges of climate change. It also identifies new opportunities presented by the changing growing season. For example: some farmers are taking advantage of warmer, drier conditions to test out different crops, such as wine grapes and fruit trees.
