Hurricane History

Saint Martin lies in one of the most hurricane-prone zones of the eastern Caribbean. Hurricane Donna (1960, Category 4) caused extensive destruction across the island, killing seven people and leaving a quarter of the population homeless. Hurricane Luis (1995, Category 4) stalled near the island for roughly 24 hours with sustained winds of 217 km/h135 mph, damaging or destroying approximately 60% of the island's houses, killing nine people on Saint Martin, and causing an estimated $1.8 billion (1995 USD) in damage across the region.

Hurricane Lenny (1999, Category 4) followed an unusual west-to-east track and battered the island with 209 km/h130 mph winds from the southwest, killing 13 people and causing severe flooding on the southern coast.

Hurricane Irma (2017, Category 5) was the most catastrophic storm in the island's recorded history. Irma's eye passed directly over Saint Martin on September 6 at peak intensity with sustained winds of 295 km/h185 mph, damaging approximately 95% of structures island-wide. At least 11 deaths were reported across both the French and Dutch sides, and total damage exceeded $2 billion.

Hurricane Gonzalo (2014, Category 1) also caused notable damage, uprooting trees and knocking out power across the island.

Geography & Terrain

Saint Martin is a hilly volcanic island covering 87 km²34 sq mi, divided between France (the northern 53 km²20 sq mi) and the Netherlands (the southern 34 km²13 sq mi). It is the smallest inhabited island shared by two sovereign nations.

The highest point is Pic Paradis at 424 m1,391 ft on the French side, and a chain of hills runs through the centre of the island. The coastline stretches roughly 59 km37 miles and features 37 named beaches.

Simpson Bay Lagoon, one of the largest inland lagoons in the Caribbean, straddles the French-Dutch border. The Dutch side is home to Princess Juliana International Airport, famous worldwide for its extremely low-altitude landing approaches over Maho Beach. Anguilla lies just 15 km9 miles to the north, and Saint Barthelemy is roughly 32 km20 miles to the southeast.

The hills along the island's central spine provide modest orographic lift, which helps trigger afternoon showers during the wet season, particularly on the eastern windward slopes. However, the island's relatively low elevation means it does not generate the heavy orographic rainfall seen on taller volcanic islands such as Dominica or Guadeloupe.

The low-lying southern coast and narrow sand spits are particularly vulnerable to storm surge during hurricanes. Trade winds arriving from the east and northeast blow largely unobstructed across the island, keeping coastal areas comfortable but also funnelling wind through the gaps between the central hills.
