That does sound far too high. Run the tap for a few minutes and take it again.
Ground temperature around a metre down (where the street water main should be) is supposed to stay pretty constant all year round. I'd expect + few degrees.
You might find a clue on soil temps underground by looking at Ground Source heat pump calculations?

I found around 5 to 7 deg C in the winter.
Indeed - it stays at about 55F (12.8C) year-round at our place (in the US) despite an air temperature swing of 110F or more. That's from a private well of about 80' deep, and connecting pipework about 7-8' below ground level.
cheers

About 5 degC.
I did run it for a few minutes. I was very surprised how high it was, but it was.

Round here however long you run it the water is very cold in winter and too warm to be refreshing in winter. Used to have an electric shower running from the mains. Needed completely different settings in summer from winter.
thanks everyone. The figures were used in a new section on the wiki

We still do and our experience is the same.
21C does sound very high. Ground temp at regulation 750mm depth ought to be around 10 to 15C and fairly steady summer/winter. Of course the source water temp in an open reservior may well vary quite a bit so depending on how far you are from that reservior... I guess treated water stored in a water tower will also warm a bit during the summer.
Mine is currently 19.5C
19.7 here, much to my surprise.
