When are the earliest and latest sunrise and sunset in Porto Velho?

The earliest sunset of 2026 in Porto Velho falls on 26 May at 18:02, 26 days before the June solstice, and the latest on 27 January at 18:43.

Sunrise runs on its own schedule: earliest on 15 November at 05:44, latest on 13 July at 06:31, 22 days after the June solstice. The four dates in the table below do not line up with the solstices, and they are not supposed to. Earth's orbit is slightly elliptical and its axis is tilted, so the sun runs a few minutes fast or slow against clock time through the year. That offset, the equation of time, is what pushes the earliest sunset ahead of the shortest day and the latest sunrise behind it.

How long does twilight last in Porto Velho?

First light in Porto Velho arrives 21 minutes before sunrise today, at 05:38. After sunset the light hangs on for another 21 minutes, until 18:31. That evening stretch is not the same all year in Porto Velho: it runs from 21 minutes at its shortest, in March, to 23 minutes at its longest, in December. The lower the angle at which the sun crosses the horizon, the longer twilight lasts, which is why dusk is a slow affair at high latitudes and abrupt near the equator.
