Mid October - late December: Gunumeleng – Pre-Monsoon Storm Season

Gunumeleng is a pre-monsoon season that can last from a few weeks to a few months. From mid-October to late December, visitors can expect hot weather that becomes more and more humid. With thunderstorms in the afternoons and scattered showers throughout the day, the rain brings life to the landscape and new growth from the plants becomes more widespread.

Sometimes, as the streams begin to run, acidic water rushes down from the floodplains and into the billabongs, decreasing the oxygen levels in the water and causing fish to die. You may begin to notice waterbirds in abundance as new growth becomes more widespread and barramundi begin to migrate from waterholes to the estuaries downstream to breed. 

January - March: Gudjewg – Monsoon Season

Kakadu's true wet season occurs between January and March when the land is drenched with regular thunderstorms, heavy rain and flooding. Plant and animal life during these months thrive thanks to the increase in water, heat and humidity. Speargrass in the national park can grow up to two metres tall throughout the woodlands. 

April: Banggereng – Storm Season

Also referred to as "knock 'em down" season, Banggerreng is characterised by early, strong windy storms that roll through and flatten the speargrass that has been thriving between January and March. From mid-April, rain clouds disperse and with it, the vast expanses of floodwater and streams begin to run clear. With clear skies and sunny days, this is a time when plants begin to fruit and animals care for their young.

May - Mid June: Yegge – Cooler but still Humid Season

While the southern states of Australia shiver through winter, Yegge in Kakadu is relatively cool with low humidity. During this time, waterlilies carpet billabongs and shallow wetlands, providing picture-perfect scenes in areas such as the Yellow Water Billabong.

Spend your mornings gazing over the misty plains and waterholes in the early hours, or your afternoons admiring the flowering woolly butt flowers in bloom. 

Mid-June - Mid-August: Wurrgeng – Cold Weather Season

The 'coldest' months in Kakadu are not considered cold by any stretch of the imagination, as daytime temperatures hover around 30°C and evenings dip to 17°C. This is prime time to go cycling in the Top End (or on a walking trip with our mates from World Expeditions), thanks to its clear blue skies, sunny days and manageable temperatures. You're more likely to see an abundance of waterbirds around billabongs, as the waterholes begin to drink after months of no rain. 

Mid-August - Mid-October: Gurrung – Hot Dry Weather

Typically hot and dry, the early spring months are pleasant and can offer travellers a chance to see wildlife, such as long-necked turtles laying their eggs on some of Kakadu's sandy beaches.

Towards mid-October, temperatures build alongside the thunderclouds, signalling the approaching pre-monsoon season.
