Teresina regularly exceeds 40°C and is the hottest state capital in Brazil. It is also the only one not on the coast in the northeast, built inland at the confluence of two rivers in 1852.
The clock: Teresina keeps UTC−3. It was purpose-built as a capital, replacing Oeiras — one of very few planned capitals in 19th-century Brazil.
Teresina lies at 42.8°W. Its time zone, UTC−3, is built around the 45°W meridian. The 2.2° gap between them means the clock runs roughly 9 minutes behind the sun: solar noon arrives at about 11:51 rather than 12:00. The zone holds UTC−3 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 12h 25m of daylight. The shortest is 22 June, with 11h 50m. The swing between them is 35 minutes. Within a few degrees of the equator the length of the day barely moves all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Teresina the sun comes up earliest on 10 November at 05:26, while the latest sunset waits until 5 February at 18:14. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Teresina that civil twilight runs about 21 minutes at the equinox.
