⚠ May sits at the tail end of the cyclone season, which officially runs November through April. Late-season tropical disturbances are uncommon but not impossible in early May. They can disrupt inter-island boat and flight schedules for several days. Monitor regional weather advisories before and during travel.
⚠ Afternoon squalls hit fast. They bring brief, intense downpours. Sea conditions shift without warning. Calm waters turn choppy in minutes. Open crossings to Tetepare and the Russell Islands demand extra caution. Pack a dry bag. Check forecasts daily.
