Catió, Quebo and settlements in the south

Tombali occupies the southern part of Guinea Bissau. Catió is the regional capital and a central reference for administration and local searches. Quebo, also known historically by another name, is an important inland town and sector centre.

Bedanda and Cacine are additional places associated with the region. Cacine lies toward the southern coast and estuarine area, while Bedanda serves communities farther inland. Settlement rankings can vary because sources may count urban cores and surrounding administrative areas differently.

Catió — the capital of Tombali Region. Quebo — a prominent inland settlement. Bedanda — a town and sector centre. Cacine — a southern coastal and riverine settlement. However a database categorises them, these locations share one time zone. Only location-sensitive information such as sunrise requires a separate local calculation.

Sunrise across Tombali

Tombali’s combination of inland, coastal, and estuarine locations makes a precise place selection useful. The sunrise calculated for Catió may not match the exact minute calculated for Cacine or Quebo, despite all three clocks being synchronized.

The result changes gradually through the year because the apparent solar path changes with the season. The time-zone offset does not need to change for this to happen. Civil time and solar time describe related but different things.

For an early departure, choose the destination and correct date, then consider conditions that a calculation cannot predict. Dense vegetation, cloud, haze, buildings, or the shape of the horizon may affect when direct sunlight is visible. Dawn begins before sunrise, so usable natural light may arrive earlier than the sunrise label suggests.
