Insider timing tips

  • The 'long rains' from April to May bring persistent, heavy downpours that can disrupt travel and beach activities.
  • The dry seasons (June-October and December-February) offer the most reliable weather, but also coincide with peak tourist demand and prices.
  • Shoulder months like June and September offer a good balance of decent weather and fewer crowds than the absolute peak months of July and August.
  • While November sees the start of the 'short rains', these are often brief showers rather than prolonged downpours, offering a budget-friendly window if you don't mind occasional rain.
