Sint Maarten, a small Caribbean island of about 34 km², features a tropical monsoon climate (Köppen Am) with warm temperatures year-round, high humidity, and a distinct wet season from October to January. Average highs range from 29-31°C, with minimal seasonal variation, making it ideal for beach living but prone to hurricanes and heavy rains during wet months. Annual rainfall typically totals 900-1200 mm, concentrated in short intense showers, while trade winds provide cooling breezes. Sunshine averages over 2800 hours yearly, appealing to expats seeking sunny paradise, though rising temperatures and potential rainfall declines due to climate change warrant preparation for hotter, drier conditions.

Island-wide (Princess Juliana Airport area)

Sint Maarten's compact size results in uniform tropical climate across the island, with steady warmth from 24-31°C year-round. Wet season (Oct-Jan) brings frequent showers totaling ~60-100 mm monthly over 15-17 rainy days, while dry season (Feb-Sep) offers clearer skies and less precipitation. Trade winds moderate the heat, but high humidity persists. Recent projections indicate +1-3°C warming by 2100 and possible 50% rainfall drop in severe scenarios, heightening drought risks for residents planning long-term stays.
