City wants your King Tides photos to help predict our future shoreline
Extremely high tides known as king tides will lap against Vancouver's shorelines until November 30. This phenomenon happens twice a year and offers us a chance to visualize what normal sea levels will look like in the future as levels rise due to climate change.
Share your photos
We are asking residents to snap photos of the shoreline during king tide season to support the City's engagement efforts and compare with the coastal flood maps we have created to understand vulnerable areas.
Share your photos through our Sea Level Rise Story Map by adding the date, time and location to photos and uploading.

Earlier this year, we collected nearly 400 photos during the January king tides, which we compared with existing flood data and sea level rise projections. Additional images will help broaden the conversation on how our shoreline is changing, as we continue to build a thorough understanding of local risks and vulnerabilities to sea level rise, and map out the potential options to protect and adapt our coastline.
King Tides can reach as high as five meters in elevation, about a meter higher than a normal high tide as a result of the sun and moon's gravitational forces reinforcing one another. By 2050, normal winter high tides will be more like today's annual king tide, meaning king tides and storms will lead to floods every year.
Climate Change Adaptation Strategy
To address the concern of future sea level rise the City has developed a Climate Change Adaptation Strategy, is working to reduce our greenhouse gases, and is in the process of developing a strategic plan for coastal flood and erosion risk due to increasing sea levels.
In July 2018, Council also approved recommendations to prepare the city's vulnerable areas for sea level rise by implementing and planning for coastal flood protection. The recommendations focus on engagement, development, and design along the City's coastline ensuring sea level rise is considered in future and ongoing developments.
