Singapore is in its haze season right now, June to September. Skies go white, views disappear and air quality can drop for days at a time — a proper mask is worth the space.
Going in August
The stretch when transboundary haze is most likely, when light winds carry smoke across from regional fires. Some years it barely appears; in a bad year visibility and air quality drop for days.
What this means for your bag
A proper mask
A fitted FFP2/N95 — a cloth or surgical mask does nothing against smoke particles. Worth it if you have asthma or are travelling with children.

Malls, buses and restaurants are cooled far below the street, and the swing is what makes people ill. A light long sleeve doubles as sun cover and as dress code for temples and mosques.
