Cairns weather by month
Climate source: Meteorological data for Cairns is based on weather statistics gathered for the 30-year period 1991 to 2020 by the Bureau of Meteorology (BoM) from the closest weather station: Cairns International Airport (CNS), located 7km (4mi) north of Cairns CBD.
Advice on the best time to visit Cairns is based on average local weather statistics, when the weather conditions are generally better than at other times of the year. We consider high and low temperatures, risk of rain (and thunderstorms, etc.), amount of sunshine and sea temperature. For general outdoor activities we favour clear, rainless days with a temperature range between 18°C (64°F) and 27°C (80°F); and for hot-weather activities we favour clear, rainless days with a temperature range between 24°C (75°F) and 32°C (89°F). Often, the best times to visit correspond to high season and therefore involve higher prices. Dew point temperature measures moisture content in the atmosphere: a higher dew point feels more humid, while a lower dew point feels drier.
