The Northern Mariana Islands have a warm, humid tropical maritime climate with very little temperature variation through the year. Coastal conditions are shaped by the Pacific Ocean, seasonal trade winds, a drier period from December to June, and a wetter season from July to November that can include typhoons. Average temperatures are typically in the upper 20s C, with high humidity making it feel warmer than the thermometer suggests. Annual rainfall is substantial, and the islands experience a clear seasonal shift between drier and wetter months. This climate is attractive for people who prefer year-round warmth and sea breezes, but residents and expats should plan for humidity, intense sun, and storm-related disruptions.
