Miami's subtropical climate means warm, humid air year-round, affecting transparency — but the trade-off is access to deep southern-sky objects that are difficult or impossible from higher latitudes. The Everglades, just 30 minutes west, offer Bortle 4 skies with a vast, flat horizon. Miami's latitude (25.8°N) is the lowest of any major US city, making Canopus, the Southern Cross (barely), and low-declination targets more accessible. Winter cold fronts bring the clearest conditions; summer is humid but occasionally clear.
