Clothing
Light, breathable fabrics for the heat outside, plus one light layer for the aggressively air-conditioned malls, museums, and MRT trains — the temperature swing indoors to outdoors is real.
Rain gear
A compact umbrella or light rain jacket covers the short, intense afternoon downpours that are a near-daily feature outside the driest months.
A few other essentials
Comfortable walking shoes, sun protection, and a reusable water bottle — tap water is safe to drink island-wide.
