What are King Tides?

King tides are the highest tides of the year, and in San Diego, they typically occur in the winter months. These tides can cause coastal flooding and erosion. They can also impact the local ecosystem by altering the distribution of saltwater and freshwater in estuaries and wetlands.

In San Diego, the king tides are caused by a combination of factors including the gravitational pull of the moon and the sun, as well as the shape of the coastline. The tides can be up to two feet higher than the average high tide, and can flood low-lying areas such as beaches, streets, and parking lots. King tides can also have an impact on the local ecosystem, as they can alter the distribution of saltwater and freshwater in estuaries and wetlands. This can have a negative impact on fish and wildlife, as well as on plants that depend on a specific balance of salt and freshwater.

King Tides City Impact

The City of San Diego has taken steps to address the impacts of king tides. The City has installed tide gates and sea walls to prevent coastal flooding, and working with local organizations to educate the public about the impacts of king tides and how to prepare for them.

Additionally, the city is working to improve the resilience of the coastal ecosystem by restoring wetlands and other habitats. These areas act as buffers against the impacts of king tides. This work includes planting native vegetation and creating wildlife corridors to connect fragmented habitats, as well as removing non-native plants and animals.

King Tides & Climate Change

King tides are not caused by climate change, but they are being made worse by sea level rise caused by global warming. As sea levels rise, the impacts of king tides become more severe and more widespread. It is important for coastal communities to take steps to prepare and adapt to these events.

King tides can be predicted using tide charts and tide tables, which show the predicted tide heights and times for specific locations. These predictions are based on the relative positions of the sun, moon and earth, as well as the shape of the coastline.

Coastal communities can take steps to prepare for king tides by staying informed about tide forecasts, avoiding low-lying areas during high tide, and protecting property by raising electrical outlets and appliances. Additionally, communities can take steps to improve the resilience of the coastal ecosystem by restoring wetlands and other habitats that act as buffers against the impacts of king tides.

How to prepare for King Tides?

There are several steps that coastal communities can take to prepare for king tides:

• Stay informed: Keep track of tide forecasts and pay attention to weather conditions that could exacerbate the effects of king tides.

• Avoid low-lying areas: During high tide, avoid areas that are prone to flooding, such as beaches, streets, and parking lots. Flooding Map.

• Protect property: Raise electrical outlets and appliances, and make sure that any valuables are stored in a safe place.

• Create a flood plan: Develop a plan for dealing with flooding, including evacuation routes and emergency contact information.

• Improve coastal resilience: Restore wetlands and other habitats that act as buffers against the impacts of king tides.

• Educate the public: Educate the public about the potential impacts of king tides, how to prepare for them, and how to stay safe during high tide.

• Address the root cause: Sea level rise caused by global warming is exacerbating the effects of king tides, it’s important to address this root cause by taking measures to reduce greenhouse gas emissions, and implement sea level rise adaptation measures.

It is also important to note that king tides are not unique to a specific area, they occur in many coastal areas around the world, and their impacts will become more severe and widespread in the future as sea level rise continues. Therefore, it’s important to plan ahead, and to be prepared to adapt as sea levels continue to rise.
