French Polynesia is not typically affected by hurricanes, also known as typhoons or cyclones. These are large storm systems that form over warm ocean waters and have winds that can reach up to 74 mph or more. These storms usually form near the equator in tropical regions and move westward or northwestward. French Polynesia is not located in such a region, and that is one of the main reasons for its lack of hurricanes.
Location of French Polynesia
The location of French Polynesia plays a significant role in its lack of hurricanes. The islands are located in the South Pacific Ocean, outside of the area where hurricanes typically form and move, which is primarily in the North Atlantic Ocean and the northeastern Pacific Ocean. The main hurricane belt lies north of the equator, between 10 and 20 degrees latitude, which is well north of French Polynesia. This means that the islands are not typically in the path of storms that form in this area.
Additionally, French Polynesia is also outside of the area where hurricanes typically move, which is primarily to the west. The islands are located east of the International Date Line, which means that storms that form in the western Pacific Ocean and move westward will not typically reach French Polynesia.
The climate of French Polynesia also plays a role in its lack of hurricanes. The islands have a tropical climate, which means that they experience warm temperatures and high humidity throughout the year. However, the islands are not located in the area of the tropical Pacific Ocean where hurricanes typically form, known as the “hurricane breeding ground.” This area is located near the equator and is characterized by warm ocean temperatures, low wind shear, and high atmospheric moisture. French Polynesia is located south of the equator, which means that it is not in the hurricane breeding ground.
The wind shear, or the difference in wind speed and direction at different levels of the atmosphere, is also a key factor that affects the formation of hurricanes. Hurricanes require low wind shear to develop, as wind shear can disrupt the formation of the storm and prevent it from strengthening. French Polynesia has relatively high wind shear, which makes it difficult for hurricanes to form or strengthen.
The El Niño-Southern Oscillation (ENSO) is a climate pattern that can have a significant impact on the frequency and severity of hurricanes in the Pacific Ocean. El Niño and La Niña are the two phases of the ENSO, with El Niño characterized by above-average sea surface temperatures in the eastern Pacific Ocean and La Niña characterized by below-average sea surface temperatures in the same region.
During El Niño, the region of French Polynesia experiences an increase in the wind shear which can inhibit the development of hurricanes, and with La Niña, there is a decrease in wind shear in that region making it easier for hurricanes to form. This can affect the frequency of hurricanes in French Polynesia, but it is not a major concern for the area.
Other types of severe weather
Even though French Polynesia is not typically affected by hurricanes, it can still be impacted by other types of tropical storms and severe weather. The islands can be affected by tropical storms, which are weaker than hurricanes but can still cause damage with high winds and heavy rainfall. Additionally, French Polynesia is also affected by storm surges, which are caused by the rise in sea level due to strong winds and low pressure associated with tropical storms and hurricanes. Storm surges can cause flooding in coastal areas, damage to buildings and infrastructure, and erosion of beaches.
French Polynesia is also affected by high winds, which can cause damage to buildings and power outages, and heavy rainfall, which can lead to flash flooding and landslides. These types of severe weather can occur during the cyclone season, which typically runs from November to April, but can happen in any month.
Preparation and response
The government of French Polynesia is responsible for preparing for and responding to severe weather, including tropical storms and hurricanes. They have set up warning systems and emergency response plans to minimize the impact of these events on the population. The public is advised to stay informed about weather forecasts and any warning issued, to prepare emergency kits and have evacuation plans ready.
It’s important to note that French Polynesia is a popular tourist destination, and travelers should also be aware of the potential for severe weather and take appropriate precautions. It is always recommended to check the weather forecast before planning a trip and keep an eye out for any warnings or alerts issued by local authorities.
In conclusion, French Polynesia is not typically affected by hurricanes. This is because the islands are located in the South Pacific, outside of the area where hurricanes typically form and move. The location, climate, and wind patterns in French Polynesia do not favor the formation of hurricanes. However, the islands can still be affected by other types of tropical storms and severe weather. Therefore, it is important for both the government and the public to be prepared for and respond to these events to minimize their impact.

The main reason is that the islands are located in the South Pacific Ocean, outside of the area where hurricanes typically form and move, which is primarily in the North Atlantic Ocean and the northeastern Pacific Ocean.
The islands are located south of the equator and east of the International Date Line, which means that they are not typically in the path of storms that form in the main hurricane belt (which lies north of the equator, between 10 and 20 degrees latitude) and not where the storms move westward.
French Polynesia has a tropical climate, but it is not located in the area of the tropical Pacific Ocean known as the “hurricane breeding ground,” which is near the equator and characterized by warm ocean temperatures, low wind shear, and high atmospheric moisture. Additionally, French Polynesia has relatively high wind shear, which makes it difficult for hurricanes to form or strengthen.
Yes, French Polynesia can be affected by other types of tropical storms and severe weather such as tropical storms, storm surges, high winds, and heavy rainfall. These can occur during the cyclone season, and can have an impact on the infrastructure, people and economy of the islands.
