When to go

Best time to visit Flores Island

Flores diving and snorkeling are possible yearround, but conditions are strongly seasonal and weatherdriven.

Best overall window

Jun to Sep

More stable weather, calmer seas, and warmer water near 22°C to 25°C.

Outside that window

Higher swell and more storm systems. Build buffers for flight and ferry disruption.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.

    Bigger Atlantic swell can limit boat diving and exposed swimming.

Always true for this destination
  • Flores is remote, so flight capacity drives prices.
Seasonal cautions
  • Apr to May, Oct to Nov: Good value and fewer crowds. Water is cooler (often 16°C to 21°C). Expect more changeable skies.
  • Dec to Mar: Higher swell and more storm systems. Build buffers for flight and ferry disruption.
