São Tomé is located at 0.34°N, 6.73°E. Its latitude determines how dramatically daylight hours change through the year.
The city uses the Africa/Sao_Tome timezone (GMT). It does not observe Daylight Saving Time, so solar times shift gradually through the year without abrupt clock changes.
Solar noon — the moment the sun reaches its highest point in the sky — occurs when the sun crosses the local meridian. In São Tomé this falls around 11:32 in mid-summer and 11:23 in December, reflecting UTC offset and any DST adjustments.
