Tides and Extreme Tide Events

What causes tides? What are king tides? Tides are the daily rise and fall of sea levels, caused The term king tide is commonly used to describe an mainly by the gravitational pull of the moon as it revolves especially high spring tide. King tides occur a few times around the earth. Tides are also affected by the earth’s every year, when the gravitational pull of the sun and rotation and the gravitational pull of the sun. moon upon the earth is strongest. This happens when the moon is closest to the earth in its monthly orbit. When this coincides with a spring tide, it will produce an especially high tide, or king tide. In the Pacific, the highest king tides often occur during the months from November to March, when the earth is also closest to the sun in its annual orbit.

What do I need to know about king tides? King tides are a natural part of the tidal cycle and are Figure 1. Low and high tide in Suva, Fiji. Photo: Molly Powers-Tora (2018). predictable. A king tide can cause coastal flooding, even on a clear, sunny day. What are spring tides and neap tides? When king tides coincide with cyclones, floods or storms, water levels can rise significantly, potentially Spring and neap tides are part of the normal tidal cycle causing damage to property and the coastline. The and occur regularly, usually twice per month. actual height reached by a king tide will depend on the Spring tides are very high tides and very low tides that local weather and ocean conditions on the day. occur during full and new moon phases, when the It is also important to know that king tides have always gravitational forces of the sun and moon combine to occurred and are not a result of sea level rise. exert a stronger pull on the oceans. During the moon’s quarter phases each month, the sun and moon are at right angles, and the gravitational forces cancel each other out, resulting in lower high tides and higher low tides called neap tides.

Sea-level rise: Through assessing observations and research, the Intergovernmental Panel on Climate Change (IPCC) concluded that global average sea levels have been rising at a rate of about 3 mm per year since 1993. Levels were 225 mm higher in 2012 compared to 1880. Sea-level rise can contribute to higher tides, but the rates are not the same at all locations.

The Pacific Sea Level and Geodetic Monitoring Project provides sea level and meteorological information for 13 countries and tide predictions for 20 locations in the Pacific region. It is an important resource for those involved in disaster mitigation and adaptation planning, coastal development, and the shipping, fishing and tourism industries.

Traditional knowledge is the knowledge held by those living off the land and ocean, be they indigenous or non- indigenous. This knowledge is not static and can evolve over time and is often imbedded in practice and belief. By closely observing their local environment, communities in the Pacific have developed skills that enable them to build coping strategies for variable weather and climate conditions, including oceans and tides. Figure 1. In Fiji, when flocks of seabirds locally known as ‘Toro’ or Brown Booby (Sula leucogaster) are seen diving into the sea, it is a signal that a large school of fish is nearby. (Photo: A Daphne) Understanding tides and oceans Pacific communities have long used traditional methods of preparing for and responding to natural hazards, including tsunamis. For remote communities, or when natural hazards occur before official warnings can be received, these traditional approaches are particularly important for saving lives.

In many Pacific nations, unusual animal behaviour can indicate an approaching tsunami. This includes dogs making strange noises and cats, chickens and dogs running to higher ground. Other signs or indicators of tsunamis include the retreat of sea water and unusual environmental sounds. A traditional response to these signs is to move to higher ground. Tropical cyclones are also predicted through close observation of the oceans. For example, in the Solomon Islands, unusual current movements around the island of Tikopia, accompanied by seabirds flying along the coast and facing the ocean, were used to predict Tropical Cyclone Zoe in December 2002. In Tonga, before the arrival of Tropical Cyclone Gita in February 2018, coastal sea Figure 3.
