Pack for warm, humid weather with lightweight clothing, reef-safe sunscreen, a light rain jacket, and water-resistant bags for excursions—October can bring short tropical showers. Because October is inside Atlantic hurricane season, buy flexible fares or travel insurance that covers hurricane-related cancellations and monitor forecasts from the Bahamas meteorological service before and during travel. At San Francisco International Airport (SFO), allow extra time for international departures and use Global Entry if eligible to speed re-entry on return. When landing at Lynden Pindling International Airport (NAS), pre-book transfers to Nassau or Paradise Island, and keep digital copies of travel documents and emergency contacts. CTA: Add travel insurance for hurricane coverage and double-check local weather two days before your October trip from SFO to NAS.
