If you feel that you have a world beating record from your “All Time Records – Highs and Lows” then post it on the forum clearly indicating the record(s) you are claiming. Please include your website address (if applicable), together with location and how long you’ve been running Cumulus (Steve needs this to check off who has donated…. only joking
I’m sure it will be interesting to see this data from around the world, so good luck

Special mention
* I'll just add that back on the 7 Feb 2009 I measured 46.5 with a mercury thermometer positioned where my weather station sensor now is.
* Although it is recorded by Cumulus, it doesn't appear on the records page, I think WestOz's record of 78 days without rain should be listed.
* I have recorded a high of 37.0° C in August 1995 and a low of -43.5° C in January 1994 - a range of 80.5°.
