Unique Feature: Macapá

Only capital city in the world straddling the equator (Monumento do Marco Zero).
Sun rises/sets vertically at equinoxes. No shadow at solar noon.
Stadium (Zerão) has midfield line on equator — teams defend different hemispheres.

Equatorial: hot (26–32°C), humid, no dry season (Amapá) or short dry (Roraima). Rainforest or savanna (lavrado).

These are the closest — but "close to equator" in Brazil means deep Amazon, not beaches.
