December is moderate for Johor Bahru.
December is the northeast monsoon peak and one of JB's wettest months, around 31°C/23°C with frequent heavy downpours, yet it's also one of the busiest travel periods thanks to year-end and Singapore school holidays.
That combination means heavy Causeway jams, packed malls and theme parks, and higher hotel prices — book ahead, cross the border early, and avoid peak holiday evenings. Build a rain-flexible itinerary: clear-morning sightseeing, and malls, SEA LIFE, and food courts on the stormy afternoons.

Johor Bahru in December — Full Picture
December is the northeast monsoon peak and one of JB's wettest months, around 31°C/23°C with frequent heavy downpours, yet it's also one of the busiest travel periods thanks to year-end and Singapore school holidays.
That combination means heavy Causeway jams, packed malls and theme parks, and higher hotel prices — book ahead, cross the border early, and avoid peak holiday evenings. Build a rain-flexible itinerary: clear-morning sightseeing, and malls, SEA LIFE, and food courts on the stormy afternoons.
The Desaru sea is rough and beach days are unreliable this month, so plan around the city, theme parks, and indoor attractions. Despite the rain, the festive atmosphere and the buzz of cross-border holiday crowds are part of the experience.
Pack a reliable umbrella or poncho and quick-dry footwear, plus light clothing and sunscreen for the breaks between storms.
What to Wear & What to Pack
Hot, wet, and at the monsoon peak — about 31°C/23°C with frequent heavy downpours. Light breathable clothing, a reliable umbrella or poncho, quick-dry shoes, and sunscreen for clear spells. A layer for air-conditioning indoors.
