Be prepared for higher than normal tides along the Washington coast in 2024 and 2025. King tides, also known as perigean spring tides, occur when the moon is closest to Earth during a new or full moon. This alignment of the Earth, moon, and sun creates stronger gravitational pull on the tides. As a result, the high tides are higher, and the low tides are lower than usual.

The highest king tides of the year are expected to occur in January and February of both 2024 and 2025. During these months, tides could reach up to 13 feet in some areas. While king tides are a natural phenomenon, they can cause flooding and erosion in low-lying coastal areas. Additionally, king tides can make it difficult to access beaches and other coastal areas.

If you live in a coastal area, it is important to be aware of the king tide schedule and take precautions to protect your property. You can find the king tide schedule for your area online or by contacting your local tide station. During king tides, it is best to avoid low-lying coastal areas and be prepared for flooding. You should also secure any loose objects that could be washed away by the high tides.

Mapping the Impact: Forecasting King Tide Hazards in 2024-2025

Predicting the Extent of Flooding

King tides, also known as perigean spring tides, occur when the sun, moon, and Earth align, resulting in exceptionally high and low tides. In 2024-2025, king tides are predicted to reach significant heights in Washington. To prepare for their potential impact, comprehensive mapping efforts are underway to identify areas vulnerable to flooding. By leveraging tide data, topographic information, and historic flood records, researchers can develop detailed hazard maps pinpointing regions at risk. These maps will serve as invaluable tools for coastal communities, enabling them to prioritize mitigation measures and emergency response plans.

Factors Influencing King Tide Heights

Several factors contribute to variations in king tide heights, including:

Factor	Impact
Lunar Distance	The closer the moon is to Earth, the stronger its gravitational pull, leading to higher tides.
Solar Alignment	When the sun and moon are aligned with Earth, their combined gravitational force amplifies the tidal range.
Coastal Topography	Bays and estuaries act as funnels, amplifying tidal fluctuations and exacerbating flooding.

Mitigation Strategies: Preparing for Coastal Erosion and Flooding

1. Coastal Armoring and Seawalls

Constructing coastal armoring structures, such as seawalls, bulkheads, or breakwaters, provides a physical barrier between the ocean and vulnerable coastal areas. These structures absorb and deflect wave energy, reducing erosion and protecting infrastructure and property from flooding.

2. Beach Nourishment and Dune Restoration

Beach nourishment involves replenishing eroded beaches with sediment to widen and elevate them. This provides a natural buffer against wave action, reduces the risk of coastal flooding, and enhances coastal ecosystems.
