Changes in weather

In Melbourne, Australia, the city I come from, it is not uncommon for there to be quite dramatic changes in the temperature outside. A 10C drop in as many minutes is not uncommon in summer as a change sweeps through. An example of how dramatic this can be can be seen here, from the 15th of November, 2003, 2 weeks before the official start of summer:

The nice part about this graph is that it was lovely and warm during the day (bordering on hot), so perfect weather for the beach, but by the time peek hour had arrived and everyone wanted to go home, it was rapidly cooling off. Doesn't always work that way though.

Of course it can get hot in summer, quite rapidly, too:

Footnote: there may well be other days with better illustrations of how rapidly our weather changes in Melbourne, these were just a couple I found quite quickly.
