Overview of Darwin’s Winter Climate
Darwin’s winter brings warm days and cooler nights. Rain is almost nonexistent.
You’ll feel lower humidity than in the wet season. The sun sticks around for hours, and calm, comfortable conditions make being outside a lot more enjoyable.
Location and Geographic Influences
Darwin sits right on the northern coast of Australia’s Northern Territory, about 12 degrees south of the equator. You’re closer to tropical seas here than to the dry inland deserts.
The Timor Sea and Beagle Gulf wrap around the city. They help moderate temperatures and keep nights milder than the interior.
Sea surface temperatures hang around 26–27 °C in winter, so the air stays warm and steady.
Darwin doesn’t have alpine ranges or cold fronts like southern Australia. Instead, tropical air masses and the monsoon cycle shape the weather here.
So, you don’t get extreme cold, but you do notice seasonal shifts in rainfall and humidity.
Climate Classification
Darwin’s climate falls under the tropical savanna (Aw) category in the Köppen system. You get a clear split between wet and dry seasons, not the four seasons most people know.
Winter, from June through August, lands you squarely in the dry season. Rainfall averages less than 2 mm per month, so it’s just about the driest stretch of the year.
Average daytime highs hit about 31 °C. Nights can drop to around 19–20 °C.
Humidity drops to about 55–60%, which feels so much better than the muggy wet season. All these factors combine to create a stable, sunny climate that’s easy to plan around.
Seasonal Patterns
Winter in Darwin means consistent warmth and clear skies. You’ll get 10–10.5 hours of sunshine per day. Clouds barely show up.
Rain is rare, and thunderstorms almost never happen during these months.
Winds usually stay light to moderate, averaging 12–14 kph. They keep the air feeling fresh, but it’s never disruptive.
With no heavy rain, mosquitoes don’t bother you as much, so outdoor settings feel nicer.
Unlike the wet season, where cyclones and monsoonal rains can mess up travel plans, winter is steady. It’s honestly the best time for exploring the city, coastal waters, and national parks without worrying about the weather.

Early July mornings can be the chilliest, dipping to about 62°F (17°C).

Light clothes work for the day. Maybe bring a thin layer for early mornings.

Even at its coolest, Darwin’s winter feels more like late spring or early summer elsewhere.
These steady temperatures also make winter the driest time of year. Rain is rare, and humidity is lower than in the wet season.
Comparison to Other Seasons
Darwin really only has two main seasons: the dry (May–October) and the wet (November–April). Winter sits right in the middle of the dry season.
Compared to the wet season, winter is cooler, less humid, and much more predictable.

You skip the heavy rains and storms of summer, but still get warm weather perfect for being outside.
Winter is also more comfortable than the transition months of October and November, when heat and humidity really start to climb.
Rainfall and Precipitation Patterns
Darwin’s winter months land in the dry season, so rain is almost a non-issue. You’ll see low totals, barely any rainy days, and clear skies.
It’s a totally different vibe from the rest of the year.

From June through August, rainfall in Darwin barely registers. June averages about 1.5 mm.
July drops even lower, around 1–2 mm. August might creep up a bit, but usually stays at 5 mm or less.
It’s a huge contrast to the wet season. January alone can dump over 400 mm of rain, while all of winter together rarely tops 10 mm.
You’ll get long stretches of dry weather. Muddy tracks and flooded roads from the wet season are basically gone, making winter a favorite for outdoor adventures.
Number of Rainy Days

Wind and Other Weather Factors
During Darwin’s winter months, you’ll notice steady but moderate breezes and warm sea conditions. These help shape how comfortable it feels outside and make water activities more appealing.

Darwin’s winter winds usually stay light to moderate. They average about 3 meters per second (11 km/h or 6–7 mph).
At this speed, you’ll spot movement in leaves, small branches, and flags. The air doesn’t ever feel harsh.

You won’t need a wetsuit in winter, unlike in southern Australia. The water holds its warmth, making Darwin a reliable spot for beach and marine fun during the dry season.
Calm seas and warm water come together to create steady conditions for fishing and diving. In winter, visibility often gets better since there’s less rain and less runoff clouding up the ocean.
Thinking about heading into the water? Just keep in mind that Darwin’s beaches can have seasonal hazards like jellyfish, though they don’t show up as much in the dry season. Always check local safety advice before you take a swim.
