Locked into a busy day? Here's the play.

–9am

Own the morning.The ships dock and unload mid-morning. The headline sights before nine are yours.

10–5

Go where the day-trippers don't.Away from the headline sights it stays manageable all day. Save the marquee ones.

5pm+

Take the city back.Ships sail by early evening and the squares empty out — the best hour of the day.

Need flexibility? The 10th–16th is the month's calmest stretch — the easiest window to move around in.
On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.

December weather in Singapore

Real heat — around 29°C / 84°F by day, so pace the afternoons and carry water, with rain on about 29 days, so keep a layer handy.

Singapore gets rain on about 29 days in December, so the odds of being caught out are real. What earns its bag space is a shell that packs to nothing, dries fast and has a hood that survives wind; a heavy waterproof is overkill and an umbrella is one more thing to carry through crowds.

At around 29°C / 84°F the sun is the thing to plan around. A wide brim beats a cap because it shades the neck and ears through the middle of the day, and a light long sleeve keeps the sun off without trapping heat while you walk. Browse on Amazon ↗
