Short stuff news: Today is the shortest day of the year here in the Southern Hemisphere. It also marks the Astronomical beginning of winter. Meteorologists have been here for three weeks already – please do try to keep up!).
Anyway, Cape Town will manage with just 9h53m31s of daylight today, but wow – all of that has been wall-to-wall sunshine. It’s been a stunner.
Let’s fill you in with some facts to impress your family and friends, and to annoy your enemies:
Sunrise was 7:51am this morning; sunset will be at 5:44pm this evening.
And tomorrow’s daylight will be whole 2 seconds longer than today’s.
That’s because of the sunset moving later, because the sunrise also moves later until the beginning of July. This is because the way we humans measure time and the way that the sun measures time are ever so slightly different. But because the sunset moves later faster than the sunrise moves later (still with me here?), the days do get longer.
You can see that pattern in the distance of the sun away from our little corner of Africa, as well. It reaches its furthest distance away on the 3rd July, at 152,088,000km away.
The sun was closest to Cape Town on 4th January at “just” 147,104,000km away. That means that the light from our big yellow ball takes 18 seconds more to reach us in winter than in summer.
And, to complete the comparisons, on the longest day of the year (that’s Dec 21st here):
Sunrise will be at 5:31am in the morning – 2 hours and 20 minutes earlier than today; sunset will be at 7:57pm in the evening – 2 hours and 13 minutes later than today.
That will mean 14h25m06s of daylight: fully 4h31m35s more than today.
We do have A LOT of winter to get through before those halcyon summer days (starting with Wednesday, which looks horrific), but the long journey back starts tomorrow!
