If your local flying club is at an airfield will full ATC then they are required to comply with CAP670 ATS Requirements. This in turn, with wind instruments, requires compliance with ICAO Annex 3 Meteorology if there are 'schedule journeys' by aircraft over 5,700 kgs although I think it is set to apply to all aerodromes with ATC soon. I assume Annex 3 mentions the two minute average.
Pause for breath.
If your airfield is FISO then they are recommend to comply with CAP670. If A/G then not. You might find that many do anyway, the only way to find out is to go and ask.
For the terminally bored, the reference is CAP670 ATC01 Annex A.
