#1 for local atmosphere

February

Best match

The driest and sunniest month of the year — and the most expensive.

#2 for local atmosphere

January

Best match

Peak dry season — near-zero rain, perfect seas, packed beaches and high-season prices.

#3 for local atmosphere

March

Best match

Still excellent — dry season holds, crowds ease, prices begin to soften.

#4 for local atmosphere

November

Best match

High season reopens — 95mm is very manageable and the island comes back to life.

#5 for local atmosphere

April

Strong option

Shoulder season — still mostly good but the pre-monsoon humidity and occasional showers signal change.

#6 for local atmosphere

May

Worth considering

Monsoon arrives — 185mm, rough seas, and half the island begins to shut down.

#7 for local atmosphere

June

Worth considering

Deep monsoon — most resorts closed, beaches empty, 195mm and heavy seas.

#8 for local atmosphere

October

Worth considering

Still deep monsoon at 235mm — the island is technically reopening but conditions are poor.

#9 for local atmosphere

July

Worth considering

Ghost town — 220mm of rain, almost everything closed, seas too rough for any boats.

#10 for local atmosphere

August

Worth considering

245mm: the second wettest month — deep monsoon and the island at its quietest.

#11 for local atmosphere

September

Avoid

The wettest month of the year at 260mm — hard cap forces a weather score of 2.
