What is the typical weather like for a Caribbean yacht charter?

Caribbean yacht charter weather runs 78–88°F air temp, 78–82°F water, with northeast trade winds at 12–20 mph December through April. The trades are the engine of the charter season — steady, predictable, and warm. Rain falls in 10-to-20-minute showers most days during shoulder season (November, May) and clears fast; the December-April high season runs reliably dry. Hurricane season (June through October) brings warmer water, calmer wind, and a 1-in-6 odds of a named-storm impact on any given month. Squalls during the day are common in summer and rare in winter. Humidity sits around 70–80%, high enough that the nightly AC matters. Sea state at anchor stays flat in protected bays; open-water passages between islands can pick up 4–6 foot swell.
