My tanks are all downstairs which is partly subterranean and much cooler but they are still all on about 30°c.

I had a shower last night and forgot that we'd changed over to another tank where the pipe runs along the top of the ground to the house (until it rains again and the ground is soft enough to dig) and the water coming out the cold tap alone was too hot to stand under.

So I haven't forgotten, ok.
Can you all do some rain dances or something too please as it's been more than 2 months now. The local dam that provides water to many towns and all the farms is down to about 11% and it is said that it holds as much water as Sydney Harbour when full (1995 was the last time that happened).
