Darwin's Two Seasons: Wet (Oct–Apr) and Dry (May–Sep)

Darwin, capital of Australia's Northern Territory, experiences a tropical savanna climate (Aw) with two sharply defined seasons.

Wet Season (October – April)

• Rainfall: ~1,500 mm (60") — 90% of annual total.
• Temps: 25–33°C (77–91°F), high humidity (70–90%).
• Features: Daily thunderstorms, monsoonal troughs, occasional tropical cyclones (Nov–Apr).
• Landscape: Floodplains fill; waterfalls (Litchfield, Kakadu) peak; roads cut.

Dry Season (May – September)

• Rainfall: <20 mm/month — virtually rainless.
• Temps: 20–32°C (68–90°F), lower humidity (40–60%).
• Features: Blue skies, cool nights, southeast trade winds.
• Tourism peak: "The Dry" = festival season (Darwin Festival, Bass in the Grass), optimal for Kakadu/Litchfield access.

Build-Up (October – December)

Transition period: oppressive humidity, spectacular electrical storms ("Hector the Convector" over Tiwi Islands), first monsoon bursts.

Indigenous Seasonal Calendars

Larrakia and other groups recognize 6–7 finer seasons tied to wind shifts, flowering, animal behavior—more ecologically precise than the binary wet/dry.

Visitors: Dry season for comfort; Wet season for dramatic nature (book flexible).
