St. Kitts and Nevis is most vulnerable to cyclones and hurricanes (and the resulting storm surge), floods, and droughts. The country lies on the southern edge of the Atlantic hurricane belt where tropical cyclones occur throughout August, September and October.

St. Kitts, located in the Leeward Islands of the Lesser Antilles, is situated squarely within the Atlantic hurricane belt, meaning it is susceptible to tropical storms and hurricanes. The official Atlantic hurricane season runs from June 1st to November 30th, with the highest risk of activity typically occurring between August and October. While direct hits from major hurricanes are not an annual occurrence, the island has a long history of significant encounters. Notable examples include Hurricane Georges in 1998 and Hurricane Irma and Maria in 2017, which, although not direct hits in all cases, brought devastating winds and heavy rainfall. The island's mountainous terrain can lead to localized flooding and landslides during these events. Because of this risk, modern infrastructure on St. Kitts is built to rigorous hurricane standards, and most resorts have comprehensive emergency protocols. Travelers visiting during the peak of the season are strongly advised to purchase travel insurance and monitor the National Hurricane Center updates, as even a "near miss" can result in flight cancellations and temporary disruptions to local services and island excursions.
