Monthly Variation

As the Isle of Man is about 54.5° north of the equator, the variation in the length of the period of daylight each day throughout the year is relatively high – the longest day of the year, at midsummer, is over 17 hours in length whilst the shortest day of the year, at midwinter, is just 7 hours and 20 minutes in length.

The sunrise and sunset times each month along with the time of local noon (the point at which the sun reaches its highest point in the sky) and the length of the day are summarized in the table below:

Daylight Chart

The fluctuation in the time of sunrise and sunset throughout 2020 in Douglas, Isle of Man is illustrated in the following chart.

Graph showing the variation in the length of day and night throughout the year in Douglas, Isle of Man

Note that the disjointed nature of the graph during late March and October is caused by the switch to daylight saving time for the summer months – the time at which this occurs fluctuates slightly from year to year.

The mauve bands between night and day represent the civil twilight just before sunrise and just after sunset during which the sun is below the horizon but on a clear day it is still considered bright enough to work outside without artificial lighting.
