Summer solstice

December 22, 2009

Today’s the summer solstice which gives us our longest day and shortest night.

In Dunedin the sun will be here for a second longer than it was yesterday and 4 seconds longer than it will be up tomorrow.

In Auckland the sun would have risen at 5.58 and it will set at 8.40. 

In Invercargill it rose at 5.50 and will set at 9.40. (If everyone lived down there we wouldn’t need daylight saving).

If memories from school geography serve me correctly the earth heats and cools faster than the sea. That explains why it’s usually warmer after the longest day and why it’s hotter in Central Otago than on the coast.

The sun’s shining as I type – for the third day in a row – but it’s only 10 degrees so there’s a lot of warming to do before we have summer weather.
