Cairns Weather in December

December: hot and rainy

Cairns feels sticky in December, with warm nights and frequent rain. It gets 198 mm of rain across 16 days, and cloud often softens the sunshine. November is much drier, while January is wetter still.

You can still take a reef trip or visit the Cairns Botanic Gardens, but rain and rough seas can disrupt plans. Keep a flexible day for indoor stops, such as the Cairns Museum. Hiking can feel draining in the heat, and muddy tracks may be less appealing. December is also stinger season, so don't swim at an unprotected beach.

Christmas by the Esplanade

Christmas and New Year bring festive events around Cairns, including celebrations on the Esplanade. The city's school holidays start, so families fill popular attractions and reef boats. You'll find a different pace from the quieter months, with more demand and often higher prices around the holidays.

Families who want easy swims can head to the Esplanade Lagoon, where you can cool off without entering the sea. For beach time, use a patrolled area with a stinger net, such as the one at Palm Cove.

Make room for rain

December is not the cheapest or calmest month to visit. August and September are generally better for weather, and the wet season can make outdoor plans less reliable. Still, you'll see lush greenery, and rain doesn't always last all day.

A handy Cairns-specific tip: keep the Esplanade Lagoon as your backup for a beach day. It's in the city centre, so you can switch plans without travelling far if a reef trip is cancelled or rain sets in.
