What should I pack for Vietnam in August?
High-factor sun cream
With daytime highs around 33°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.
A proper waterproof, not a folding umbrella
310 mm in the month usually arrives as heavy bursts that an umbrella will not cover.
A dry bag for phone and documents
Worth it for one downpour caught between the taxi and the door.
