Traveller notes on West Island in October
Forum posters describe October in the Cocos (Keeling) Islands as genuinely beautiful, with temperatures holding constant in the 23-31C range, alongside increased humidity but less wind than the windier winter months. Posters describe a clear seasonal pattern here: November through March runs balmy with just slight breezes, July through September brings the strongest winds (prime kite and wind-surfing season), and October sits as the standout transition month with the calmer, most pleasant conditions of the year. Posters generally rate the islands as a year-round paradise regardless of season, but consistently single out October specifically for combining warm, settled weather with a welcome break from the stronger winds of the preceding months.
Other months in West Island
Cocos (Keeling) Islands forum posters describe the climate as close to a permanent 28C, with a near-constant wind except during the 'doldrums' stretch from December into January or February, when the air goes hot and still. Locals specifically steer visitors away from that doldrums window and toward the rest of the year instead, which puts April - well clear of the doldrums but still ahead of the widely recommended July-through-October peak - in solid shape for steady breeze and the island's usual warm, settled conditions.
