December through March is peak Caribbean season — dry trade winds, calm seas, and escape from European and North American winter. Each island differs: Jamaica and Dominican Republic offer value resorts; St. Lucia and Barbados lean upscale; Cuba and Puerto Rico bring culture-heavy trips.
Hurricane season officially ends 30 November, but December is transitional — rates rise through Christmas and New Year, then soften slightly in late January before February school breaks.
Cruise ports crowd historic towns on days ships dock — check schedules for Bridgetown, Charlotte Amalie, and San Juan. Independent travellers often prefer smaller islands like Grenada, Antigua, or Turks and Caicos for quieter beaches.
Hunt winter fares on SnagAFlight with Tuesday departures and consider positioning flights via Miami (MIA) or Panama (PTY) when direct routes price high.
