Weather in Darwin and the Top End​

Darwin and the Top End, which includes the Katherine, Kakadu and Arnhem Land regions, doesn’t have winter and summer like the rest of Australia. The climate is tropical here, and the seasons are called the 'wet' and the 'dry'.
The wet season is from November to April. It’s characterised by higher humidity and monsoonal rains and storms. Temperatures typically range from 25C (77F) overnight to 33C (91F) during the day. Humidity can reach more than 80%.
In the ‘wet’, magnificent storms roll across the ocean every afternoon and the landscape comes alive with the abundant rain. Some roads become flooded at this time of year, and there’s also a risk of cyclones.
If you prefer clear blue skies, warm days and cool nights, the Top End’s ‘dry season’ is for you. That’s between May and October.​
