There are two seasons – a wet season that runs from November to May (summer) and a dry season that starts about June and stretches to October (winter). January, February and March are the wettest months and there is the greatest chance of cyclones between December and April. Temperatures are pretty stable throughout the year. Daytime temps range between 14 and 26 degrees Celsius in the dry season while visitors can expect temperatures of between about 24 to 33 degrees during the wet season. Tourists should bear in mind that the Marine Stinger season stretches from November to May.
Cairns’s city centre is small enough to walk around, but if you are planning on getting out to the Daintree National Park (a three-hour drive north of Cairns) or Kuranda Village (a 40-minute drive), renting a car is best. There are car-rental desks at Cairns Airport. Alternatively, you could take a four-wheel drive (4WD) tour. Several companies offer 4WD tours to the most popular destinations including Daintree National Park, Cape Tribulation, Cape York, Undara National Park and Chillagoe. If you’re visiting the region during the wet season (November-April) a four-wheel drive is the best way of getting around. Sunbus is the bus service around Cairns. There are eight routes, serving destinations such as the Botanic Gardens, Clifton Beach, Kewarra Beach and Yorkeys Knob.
