Kimberley wet season travel: what's open and how to do it safely
What to expect if you visit the East Kimberley in the wet season or green season: the weather, which roads and parks usually close, what still operates around Kununurra, the advantages of travelling off-peak and how to stay safe in heat, floods and cyclones.
Published
Most visitors come to the East Kimberley in the dry season, and for good reason. Roads and parks are open, the days are warm and the nights are cool. But the wet season, sometimes promoted as the green season, has its own appeal. Waterfalls thunder, the landscape turns green, storms put on dramatic shows and there are far fewer people. It also brings extreme heat, flooding, closed roads and the risk of cyclones.
This guide explains what to expect, what usually closes, what still operates and how to travel safely. Conditions change from year to year and day to day. Always check official road, park and weather sources before you travel.
The Kimberley seasons
The Kimberley has a tropical monsoon climate with two main seasons, though many locals recognise more subtle shifts.
| Period | Typical conditions |
|---|---|
| Dry season (about May to September) | Warm days, cool nights, low humidity, little rain |
| Build-up (about October to December) | Very hot and humid, with increasing thunderstorms |
| Wet season (about December to March) | Hot, humid, heavy monsoonal rain, flooding and possible cyclones |
| Knock-em-down (about March to April) | Late storms that flatten the tall grasses, followed by drying conditions |
The Aboriginal peoples of the Kimberley have their own detailed seasonal calendars, based on long observation of weather, plants and animals.
What usually closes
During the wet season, expect closures and reduced services:
- Purnululu National Park usually closes because the Spring Creek Track floods.
- The Gibb River Road is usually closed or restricted.
- El Questro typically closes or scales back operations.
- Many unsealed roads become impassable after rain, sometimes for long periods.
- Some tour operators, cafés and accommodation close or reduce their hours.
- Sealed highways can also close temporarily when rivers flood over causeways and bridges.
Closures are not on fixed dates. They depend on rainfall, flooding and road damage. Plan with flexibility.
What often stays open
Around Kununurra, a surprising amount may still be possible, depending on conditions:
- Scenic flights over the Bungle Bungles, Lake Argyle and the Argyle region often continue. Seeing the landscape green and wet from the air is spectacular. See our scenic flights guide.
- Lake Argyle is reached by sealed road, and some cruises and accommodation may operate, subject to weather.
- Mirima National Park on the edge of Kununurra is usually accessible.
- Kununurra's galleries, cafés and produce outlets continue to trade, though hours may be shorter.
- Wyndham and the Five Rivers Lookout are reached on sealed roads, subject to flooding.
Check with operators directly, as wet-season services vary from year to year.
Why visit in the green season?
- Waterfalls and rivers are at their most impressive.
- Green landscapes contrast vividly with red rock.
- Dramatic storms light up the sky.
- Fewer crowds make for quieter experiences.
- Birdlife can be prolific around wetlands.
- Accommodation may be easier to find.
The trade-off is heat, humidity, limited access and uncertainty. The green season suits flexible travellers who are happy to adapt plans daily.
Staying safe in the wet season
Heat
Temperatures in the build-up and wet season can be extreme, and the humidity makes it harder for your body to cool.
- Drink plenty of water and carry extra.
- Limit outdoor activity to early morning and late afternoon.
- Wear light, loose clothing, a hat and sun protection.
- Know the signs of heat exhaustion and heat stroke.
Flooding and roads
- Never drive into floodwater. Depth and current are hard to judge, and roads can be washed away beneath the surface.
- Check Main Roads WA for road conditions before every trip, and again on the day.
- Carry extra food, water and fuel in case you are delayed by closed roads.
- Tell someone your plans and expected arrival time.
Cyclones
- Cyclones can affect the Kimberley between about November and April.
- Monitor Bureau of Meteorology warnings and Emergency WA alerts.
- Follow instructions from emergency services, and know where to shelter.
- Be prepared to change or cancel plans.
Crocodiles and stingers
- Saltwater crocodiles become more mobile in the wet season as waterways flood and connect. Be extra cautious near any water. See our crocodile safety guide.
- Marine stingers, including box jellyfish, are present in northern coastal waters, mainly during the warmer months. Avoid swimming in the sea.
Insects
Mosquitoes and biting midges can be intense. Use repellent, wear long sleeves at dusk and follow health advice on mosquito-borne diseases.
Planning tips
- Book flexible accommodation and tours where possible.
- Allow buffer days for delays.
- Base yourself in Kununurra, where services and sealed roads are available.
- Consider flying rather than driving to and around the region.
- Check travel insurance for weather-related disruption.
Dry season or wet season?
If it is your first visit and you want to walk in Purnululu, drive the Gibb or camp at El Questro, the dry season is the clear choice. If you are flexible, enjoy the drama of tropical storms and are happy to see the Bungle Bungles from the air, the green season offers a very different and memorable East Kimberley. Read our post on the East Kimberley dry season and our when to go guide to compare.

Frequently asked questions
When is the wet season in the Kimberley?
The wet season generally runs from about November or December to March or April, with the heaviest rain usually from January to March. The weeks before, often called the build-up, are very hot and humid with increasing storms.
Is the Bungle Bungles closed in the wet season?
Purnululu National Park usually closes during the wet season because the access track floods and becomes impassable. Opening and closing dates depend on conditions each year, so check Parks and Wildlife Service WA before planning a visit.
Is the Gibb River Road open in the wet season?
Usually not. The Gibb River Road typically closes or is restricted during the wet season because of flooding, river crossings and damaged surfaces. Check Main Roads WA and the Shire for current status.
What can you do in Kununurra in the wet season?
Depending on conditions, you can often take scenic flights over the Bungle Bungles and Lake Argyle, visit Lake Argyle, see Mirima National Park, explore local galleries and produce outlets, and enjoy the thunderstorms and green landscapes. Check which tours are running, as some operators close or reduce services.
Are there cyclones in the Kimberley?
Yes. Tropical cyclones can affect the Kimberley during the wet season, mostly between about November and April. Monitor Bureau of Meteorology warnings and follow emergency advice from DFES WA.
