Sydney in May is southern-hemisphere autumn. Australian Bureau of Meteorology data put afternoon highs at 26°C / 79°F and lows at 12°C / 54°F with 8 rain days. The temperature swing of 14°C / 25°F is wider than any Northern Hemisphere May city; mornings need a wool layer, afternoons can hit 26°C / 79°F in direct sun, evenings drop back to 14-16°C / 57-61°F with the harbor wind. The defining wardrobe register is relaxed Australian quality-basics: Bassike (Sydney-based, founded 2006), Camilla (resort-luxury), Zimmermann (international Australian), Aje (contemporary), Bondi Born (sustainable). The Australian style runs less polished-tailored than European cities but more quality-conscious than American casual. Bondi, Bronte, Coogee — the eastern beach cluster — runs surf-and-coffee culture; Surry Hills runs creative-residential; Paddington is colonial-luxury; Newtown is bohemian. The harbor breeze cools evenings 4-6°C / 7-11°F below midday. Skip the heavy coat; even May in Sydney rarely needs more than a wool sweater + light jacket combination.
Sydney in May is the southern-hemisphere transition month — late autumn that still feels summery in the afternoons, but with cool 12°C / 54°F mornings that pull on a wool layer. Australians underdress by Northern-Hemisphere standards.

Daylight: 10h 35m and shrinking through the month.
Late autumn — equivalent to Northern Hemisphere November. Sydney's seasons are inverted from the Northern Hemisphere: summer is December-February, autumn is March-May, winter is June-August, spring is September-November. May is the autumn-winter transition month with mild afternoons (still 26°C / 79°F peak) but cool mornings (12°C / 54°F. June-August are the actual Sydney winter, with afternoon highs of 22-25°C / 72-77°F — still warmer than Northern European summer.
Compared to Northern Hemisphere winter cities, no — Sydney winter is mild (rarely below 5°C / 41°F even at night), and Australians underdress by Boston or Toronto winter standards. A wool sweater, a light jacket or cashmere coat, and a scarf is sufficient for the coolest Sydney mornings. Heavy coats are for Blue Mountains or Tasmania trips; in central Sydney, even Australian winter rarely needs more than mid-weight layering. The local register is relaxed quality-basics rather than heavy-coat formal.
