The best time to visit Kimberley Australia in a campervan

If you want the Kimberley without turning your camper into a slow-cooker, aim for May to August. Days are usually warm rather than savage, nights can be pleasantly cool, and the main sealed route from Broome to Kununurra is generally in its best touring shape. This is also when most caravan parks, national park campgrounds and roadhouse stops are operating at full tilt.

June and July bring the grey nomad migration, so do not roll into Broome at 5 pm expecting a powered site and a grin. Book the busy towns early, especially Broome, Kununurra and Lake Argyle. National park campgrounds in Western Australia often need online booking, and you cannot just pull up under a boab because it looks spiritual.

• Best all-round months: May, June, July and August.
• Best for waterfalls still moving: May and early June, after the wet.
• Best for fewer people: late April and September, with more heat risk.
• Do: carry at least 10–20 litres of drinking water per person for remote stretches.
• Don’t: assume every roadhouse has late fuel, LPG, potable water or EFTPOS during outages.

The Kimberley has two main moods: dry and dusty, or wet and dramatic. Broome is coastal and slightly kinder; Kununurra and the inland stations can feel like someone left the oven door open. In the dry season you may see 15–18°C mornings and 30–33°C afternoons. In October and November, 40°C is not a headline — it is Tuesday.

The wet season from roughly November to March brings humidity, storms, swollen creeks and road closures. It is spectacular from a safe, legal campsite with air-con and supplies. It is less charming when a causeway disappears and your hire agreement says “sealed roads only” in plain English.

• January–March: hot, humid, stormy; many dirt roads and remote camps closed.
• April: improving, but roads may still be drying out; check shire road reports daily.
• May–August: peak dry-season touring; book camps and powered sites ahead.
• September: warmer and quieter; good if you handle 35°C days.
• October–November: build-up heat, flies, humidity and early storms; be conservative.

The sealed Great Northern Highway gives 2WD campervans and motorhomes a proper Kimberley trip: Broome to Derby, Fitzroy Crossing, Halls Creek, Kununurra and Lake Argyle. That run is about 1,040 km without side trips, and it still feels like a Big Lap badge earned. You get boabs, gorges, huge skies and enough long, straight bitumen to have meaningful conversations with your snack drawer.

The Gibb River Road is different. It is roughly 660 km between Derby and Kununurra via corrugations, creek crossings and station country. Many standard campervan and motorhome hire agreements do not allow it, even when conditions look “not too bad” on social media. If you want the Gibb, book an approved 4WD camper and read the road restrictions before you pay.

• 2WD-friendly: Broome, Derby, Fitzroy Crossing, Halls Creek, Kununurra, Lake Argyle on sealed roads.
• Usually 4WD territory: Gibb River Road, Mitchell Plateau, many station tracks and remote gorge access roads.
• Purnululu warning: the last 53 km into the park is rough 4WD only and not suitable for standard motorhomes.
• Do: check your hire conditions for gravel roads, creek crossings and beach driving.
• Don’t: follow a local ute just because it made the crossing look easy.

In the dry season, the Kimberley’s campgrounds can feel like a travelling suburb of awnings, folding chairs and happy hour at 4:30. Powered sites in Broome and Kununurra are the first to tighten, especially during school holidays and major local events. If you need air-conditioning, battery charging or CPAP power, book online early rather than hoping for a miracle at the boom gate.

Free camping exists, but it is not a free-for-all. Use signed rest areas, obey 24-hour limits where posted, and never camp inside national parks unless you are in a designated campground with a booking. Dump points are available in the main towns, but distances are big: Derby to Fitzroy Crossing is about 258 km, and Fitzroy Crossing to Halls Creek is about 289 km. Empty the cassette when you can, not when you must.

• Book ahead: Broome, Lake Argyle, Kununurra and popular national park campgrounds from May to August.
• Useful town services: fuel, groceries, dump points, water fills and LPG swaps are mainly in larger towns and roadhouses.
• Free-camp manners: arrive before dark, keep generators within posted hours, pack out rubbish and leave no greywater puddle.
• Do: travel with a self-contained setup if your camper has one — it opens more low-cost options.
• Don’t: swim in random waterholes; saltwater and freshwater crocodiles are not there for ambience.

There is a reason locals talk about “the wet” like it has a personality. From December to March, storms can dump serious rain, creek levels rise fast, and roads can close with little warning. Broome and Kununurra may still be accessible by sealed highway at times, but remote detours, national park access and unsealed campgrounds become a moving target.

If you are set on wet-season travel, keep the plan short, flexible and sealed-road based. Expect humidity above comfort level, fewer open remote camps, and some attractions closed or inaccessible. The upside is moody skies, fewer crowds and dramatic country — but you need proper weather checks, extra water, food, fuel range and a willingness to sit still for a day or three.

• Road reports: check Main Roads WA and local shire updates before leaving town.
• Fuel range: do not run below half a tank in remote country; closures can add hundreds of kilometres.
• Heat: interior temperatures can sit around 35–40°C in the build-up.
• Do: choose powered sites if you need air-conditioning overnight.
• Don’t: drive through floodwater; even shallow-looking crossings can hide washouts.

For a first Kimberley campervan run, start with the sealed highway route and give yourself at least 10–14 days. Broome to Kununurra can be driven in three long days if you are trying to prove a point, but that is how people miss the Kimberley while technically visiting it. Distances are wide, shade is precious, and afternoon fatigue is real.

A good rhythm is to drive early, camp by mid-afternoon, and leave sunset driving to the wallabies and road trains. Dawn departures also help with heat, fuel stops and the daily campsite scramble. Before you lock in dates, check availability online for the camper size you want — longer motorhomes are comfortable, but some bush camps and older caravan parks have tighter sites.

• 7 days: choose Broome and the west Kimberley only, or Kununurra and Lake Argyle only.
• 10–14 days: Broome to Kununurra on sealed roads with proper stops.
• 3 weeks: add slower gorge time, station stays where permitted, and rest days for heat or weather.
• Do: plan fuel stops before you plan lunch stops.
• Don’t: underestimate fatigue; a 350 km Kimberley day can feel longer than it looks on a map.
