Alyangula has a tropical savanna climate (Köppen: Aw, Trewartha: Awhb/Awha), with a very hot, oppressive wet season from mid-November to April and a very warm, muggy dry season from May to mid-November, typical of the Top End region of the Northern Territory.

[8] From May to mid-November, the prevailing winds are from the east, which due to the Great Dividing Range, cast a rain shadow throughout the Top End of the Northern Territory.

Lower humidity, high winds, and lack of rain increase the likelihood of bushfires, which peak during the second half of the dry season.

Typically, temperatures at day and especially night are significantly cooler than in the Summer, which increases relative comfort.

[9] Starting from mid-November, northwesterly winds from the Arafura Sea draw in warm, moist ocean air, which leads to monsoonal rainfall, oppressive dew points and spectacular lightning storms.
