What should I pack for Indonesia in August?

  • High-factor sun cream

    With daytime highs around 31°C, burn time is short even in shade.

  • Sunglasses and a brimmed hat

    Midday glare is the part people underpack for, not the heat itself.

  • Loose cotton or linen

    Synthetics stop working once you are sweating through them all day.

  • A refillable water bottle

    Daily highs this warm need roughly double the water a temperate day does.

  • Comfortable walking shoes you can rinse

    Dry warm weather is walking weather, and dust gets into everything.
