First king tides of the season arrive in Western WA

What are king tides?

King tides are the highest high tides of the year. They occur when the moon is closest to the Earth and the sun and Earth are aligned, creating a stronger gravitational pull on the ocean's water.

When are king tides?

King tides occur twice a month, around the new and full moon. The highest king tides of the year occur during the winter months, when the Earth is closest to the sun.

What to expect from king tides

King tides can cause flooding in low-lying areas, especially during storms. They can also damage infrastructure, such as roads and bridges. Coastal erosion is another potential hazard during king tides.

How to prepare for king tides

There are a few things you can do to prepare for king tides:

• Be aware of the king tide schedule and avoid low-lying areas during those times.
• If you live in a flood-prone area, consider elevating your belongings or moving them to a higher floor.
• Have a plan in place in case of flooding, including an evacuation route and a place to stay.

King tides and climate change

King tides are becoming more frequent and more severe due to climate change. Sea levels are rising, which means that king tides can reach higher levels and cause more flooding. Additionally, climate change is causing more frequent and intense storms, which can worsen the effects of king tides.
