Weather in Cairns

Cairns enjoys a tropical climate, which means weather can sometimes be erratic. While the city experiences a dry season and a wet season, cyclone season runs from spring to autumn, three quarters of the year.

The summer months (December to February) mark the wet or monsoon season. Temperatures can reach 31°C (88°F) and it's also hot and sticky. This season provides the best time to visit the nearby rainforests, when the foliage is luxurious and the rivers and waterfalls are fully flowing. This is also when underwater visibility is best, making it the perfect season for divers and snorkelers to visit.

Autumn (March to May) is when the dry season resumes, with temperatures averaging between 22°C-29°C (71°F-84°F), both day and night.

Winter (June to August), with its cooler weather and lower humidity, is popular for sightseeing and whale-watching. Prepare for high accommodation and travel costs as this is peak tourist season.

Spring (September to November) witnesses the transition from the dry season to the wet season, and with it, plenty of humidity. Thunderstorms are common, but if you’re willing to brave the weather, you can see the Great Barrier Reef come alive in November when the coral spawns.

We update the weather data for from our weather partner every four hours. The time the last update was received is detailed here.
Actual Forecast Location: We have 830+ weather locations on the worldtravelguide.net website. Where no exact location is available we have used the nearest appropriate forecast point.
Symbols indicate the predominant weather for the day in question, calculated based on a weighting of different types of weather. So if a day is forecast to be sunny with the possibility of a brief shower, then we will see a sunny or partly cloudy symbol rather than a rain cloud.
The maximum temperature is the highest temperature forecast between dawn and dusk, and the minimum temperature is the lowest temperature expected from dusk on the day in question to dawn the next day. The temperature is in °C, or Celsius.
Wind speed and direction are the conditions expected at midday. Wind direction is based on a 16 point compass. W, SW, SSW, etc. The wind direction states where the wind originates. Wind speed is listed in MPH or miles per hour.
Humidity levels indicates how much water vapour the air contains compared to the maximum it could contain at that temperature. As a general guide:
  • 0 to 30 is very low
  • 31 to 50 is low
  • 51 to 70 is moderate to low
  • 71 to 80 is moderate
  • 81 to 90 is moderate to high
  • 91 to 100 is high
Pressure is measured in millibars (mb)
Visibility based on whether the human eye can see the following distances:
  • Very poor - less than 1km
  • Poor - between 1km and 4km
  • Moderate - between 4km and 10km
  • Good - between 10km and 20km
  • Very good - between 20km and 40km
  • Excellent - more than 40km
