Wet Season Camping: Top End and Northern WA 2026-27

When the wet season starts, and what the build-up is

Tourism NT says the Top End wet season, or tropical summer, stretches from November to April, and its green season guide puts the build-up from October to December. The Bureau of Meteorology says the northern wet season runs from about October to April in the far north of the Northern Territory, and that the monsoon normally arrives around Darwin in late December. It describes the build-up as the stretch before that onset, which is mostly inactive weather.

The official tropical cyclone season for the Australian region runs from 1 November to 30 April. Tourism NT gives typical wet-season conditions as 25°C to 33°C with humidity that can pass 80%, and says Darwin averages 429 mm of rain in January. In the Kimberley, the Department of Biodiversity, Conservation and Attractions (DBCA) says the wet runs from November to April and the rain is “usually confined to short downpours in the late afternoon or evening” but very heavy.

Agencies draw the lines a little differently, so plan around ranges. Kakadu's Parks Australia calls the monsoon season Kudjewk and gives it as December to March.

Roads and floods: how closures work

In the Northern Territory, check Road Report NT at roadreport.nt.gov.au or on 1800 246 199 before every leg. Tourism NT says some roads may be closed by flooding from November to April, that you must not travel on closed roads and that heavy fines may apply. Police, Fire and Emergency Services warn that anyone driving on closed roads can expect to be penalised.

NT Police, Fire and Emergency Services, Parks Australia and the Shire of Derby-West Kimberley all use the same line: if it is flooded, forget it. Tourism NT says that if you meet a flooded road you should wait until the water is below the wading depth in your vehicle's owner's manual, and never cross fast-flowing water, because the road surface under it may be damaged even where you cannot see it.

In Western Australia, Main Roads WA runs a live Travel Map at mainroads.wa.gov.au/travelmap showing closures and flooding, and its 24-hour line is 138 138. The Shire of Derby-West Kimberley's road report sends travellers to Main Roads for the Great Northern Highway, the Derby Highway and the Gibb River Road.

Kakadu in the wet: what stays open

Parks Australia describes the tropical summer (November to April) as vivid green landscapes, flooding, afternoon storms and fewer visitors, and says that flooding closes a number of attractions while popular areas such as Burrungkuy (Nourlangie) and Yellow Water are open all year round. The Yellow Water boat cruise typically runs all year.

What is open changes with the water. Parks Australia publishes a live Kakadu Access Report at kakadu.gov.au/news/access-and-alerts that lists each road, walk and campground as open, open with risks or closed, with a time stamp. Read it on the day, and check Road Report NT as well. Waterfalls such as Jim Jim and Twin Falls flow from the start of the tropical summer, and Parks Australia says they are best seen by air then.

Jim Jim Falls, the Twin Falls gorge and escarpment walk and Karnamarr campground are closed through 2026 while road and infrastructure upgrades are delivered, and Parks Australia expects the area to reopen for the 2027 dry season, so expect them to stay closed for this whole wet season. That is a works closure, not the usual wet-season one, and the news item on kakadu.gov.au has the latest.

You still need a Kakadu park pass. Parks Australia's tropical summer rate applies from 1 November to 14 May: an adult pass is $25 against $40 in the dry season, and a pass is valid for 7 days. Mobile coverage is limited: Parks Australia says you will not have it in most of the park.

Litchfield and Nitmiluk

At Wangi Falls in Litchfield National Park, Tourism NT says swimming is not permitted during the wet season, typically October to March, because of strong currents and the possible presence of saltwater crocodiles, while the camping and picnic facilities remain open all year. Its Litchfield camping page says Walker Creek's walk-in sites are open only in the dry season and cannot be booked in advance, and that the Florence Falls 2WD campground is available year-round, while the 4WD campground is available most of the year.

Tourism NT also says camping in the wet is possible with a robust set-up and good shelter, and that camping in Litchfield during the wet season is not recommended unless your equipment can withstand the rain. Many natural waterholes in the Top End are closed to swimming in the wet because it is unsafe.

Nitmiluk Gorge near Katherine can be visited all year. Tourism NT says that from November to April the tropical rain arrives, and when the water level rises, jet boats operate cruises on the gorge.

The Gibb River Road, Purnululu and the Kimberley parks

Main Roads WA manages the Gibb River Road. It says the road is often closed during the wet season, which generally runs from December to April, as river crossings become impassable or sections are damaged. After the wet, once crossings are low enough, crews repair flood damage and the road is reopened only when it is safe. It is typically open from May to November.

No agency publishes a fixed closing or reopening date for 2026-27, so treat the dates below as the agencies' own ranges, and use the status boards at both ends of the road, near Derby and Kununurra, and the Main Roads Travel Map for the real position. The Shire of Wyndham East Kimberley says towing trailers or caravans on unsealed roads over the wet season is not recommended.

Cyclones: who to follow

The Bureau of Meteorology issues a Tropical Cyclone Watch when gales are expected to start within 24 to 48 hours, and a Warning when gales are expected within 24 hours or are already happening. Gales are winds of 63 km/h or more.

In the Northern Territory, Tourism NT says to follow advice broadcast on local radio, to seek advice about tying down a caravan or other light structure, and to use accommodation built to cyclone code or a public shelter. Police, Fire and Emergency Services list 132 500 for floods, storms and cyclones, and 000 in an emergency.

In Western Australia, the Department of Fire and Emergency Services (DFES) uses three warning levels on Emergency WA: Advice, Watch and Act, and Emergency Warning. It says travelling and camping in areas that may be hit by a cyclone is very dangerous, and that if you are camping remotely or in a caravan park in cyclone season it is your responsibility to stay informed. It suggests booking accommodation that can withstand a severe cyclone or asking the local government about the nearest evacuation centre.

Crocodiles, stingers and mosquitoes

Tourism NT says fresh and saltwater crocodiles live in waterways across the Northern Territory all year round, so only ever swim in designated areas; if in doubt, don't swim, and avoid the water's edge. It tells campers never to camp near the water's edge, and in floods to stay out of floodwater and away from the water's edge because of the high risk of saltwater crocodiles. Parks Australia adds that crocodiles can attack in knee-deep water and that the safest place to swim in Kakadu is a public or hotel pool.

Tourism NT says marine stingers are most prevalent from October to May in the Northern Territory, to stay out of the sea in those months, and, because stings have occurred throughout the year, to take precautions all year round. If stung, flood the sting with vinegar and seek urgent medical attention. DBCA says box jellyfish and irukandji can be present along the Kimberley coast all year but are most prevalent from November to April, and advises a full-length stinger suit and vinegar.

WA Health reported on 24 March 2026 that flavivirus activity had been detected in the Pilbara and Kimberley for the first time in the 2025-26 wet season: Murray Valley encephalitis virus in mosquitoes in the Pilbara, and a flavivirus still being identified in sentinel chickens in the east Kimberley. Its advice is to avoid mosquito bites: wear long, loose-fitting, light-coloured clothing, use mosquito nets or mosquito-proof tents if sleeping outside, and apply a repellent containing DEET, picaridin or oil of lemon eucalyptus.

Heat, fuel and signal

Parks Australia says temperatures in Kakadu regularly reach 30°C or more and can exceed 40°C in summer, and strongly recommends not walking after 11 am in summer. In the Kimberley, DBCA's Purnululu page says temperatures can exceed 40°C and radiant heat can push them over 50°C. In the Pilbara, DBCA warns that flash floods can occur in Karijini's gorges, so do not enter a gorge if there is rain in the area.

Tourism NT says to keep your vehicle filled up and not rely on fuel being available in remote areas, because remote service stations have restricted opening hours. If you break down, it says to stay with the vehicle, as help may be many hours away. For the remote parts, Tourism NT suggests carrying an EPIRB or satellite phone, and DBCA suggests a personal location beacon for remote parks such as Drysdale River.

Using AussieCamps in the wet

AussieCamps lists national parks and campgrounds across the Top End and the Kimberley with the facilities, access and fees the park agency publishes, such as whether a track needs a 4WD, and a 7-day forecast from Apple Weather on each place page. Place details are stored on the phone, so they stay readable when you are out of signal; the map, directions, weather and photos need a connection.

When a campground floods or a road closes, a bookable stay is the quickest fallback. The app lists holiday parks, motels, B&Bs and tours from BookEasy that you can book in the app, and you can save places to a trip and reorder the stops as conditions change.

AussieCamps does not show road closures, flood levels or cyclone warnings, so keep Road Report NT, the Kakadu Access Report, the Main Roads WA Travel Map and the Bureau of Meteorology open beside it.
