Tuesdays. Vizcaya is closed. Several smaller institutions also close Monday or Tuesday. If Vizcaya is the reason you came, check the day before you plan around it.
Mornings. Vizcaya's gardens and the Deering Estate's grounds are unshaded and get hot by eleven from May through October. Do outdoor sites first and indoor collections in the afternoon.
Rain. June to November brings short violent afternoon thunderstorms rather than day-long rain. The bayfront museums are the standard wet-afternoon plan because they are adjacent, indoors and on the free Metromover, so you never stand in it.
Art Basel week. 4 to 6 December 2026 at the Miami Beach Convention Center, with VIP days from 2 December and satellite fairs across both cities from 30 November. Every museum programmes its strongest show for it, every hotel doubles its rate, and the traffic across the causeways is the worst of the year. Extraordinary week to be here, terrible week to arrive unplanned.
Free nights. PAMM on Thursday evenings, free second Saturdays, the third-Friday music night in Little Haiti and the last-Friday street festival in Little Havana. Between them they cover most weeks of the month.
Realistic pacing. Two institutions in a day, three if two of them are next door to each other. The driving between neighbourhoods is what defeats ambitious plans here, not the opening hours.
