Shortest Day of the Year 2024 in Papua-Nova-Guiné

The days become shorter as a result of the earth tilting away from the sun (at least in one hemisphere at a time). This causes the sun to appear lower in the sky and spend less time above the horizon, meaning the day is shorter.

The Winter Solsitice is both the shortest day of the year and also the longest night. The good news is that from this point on the days will begin to get longer until Midsummer's Night in about 6 months.

Whilst there will be more daylight going forward the same cannot be said for the temperature. This is just the beginning of winter* and temperatures will continue to drop for well over a month. The phenomena is known as seasonal lag where, despite there being more energy from the sun, the latent temperature of the Earth makes the air temperature slow to respond.

*Beginning of Astronomical winter. Meteological winter begins December 1 / June 1 (depending on hemisphere).

Winter Solstice Dates

The date of the equinoxes and solstices varies because a year in our calendar does not exactly match the length of the astronomical calendar.

The word solstice comes from Latin 'solstitium' meaning "the sun stands still". This is because the sun's path north or south stops before reversing direction.
