I would argue that really and truly they should both be just the average for the MTD or both for the complete month each day
As it is, it gives a misleading impression of how much the month has warmed as it is . November is milder than years ago on average but not by that margin
That is what I thought was said when someone raised the same question last month - I may have the wrong end of the stock though apologies if so
I think I see now. I wrongly assumed that such data would be published to the same criteria for both periods. I agree with you- not comparable and tbh not very helpful if one makes the same assumption as me! Thanks for the clarification.
I think the mtd figure is a better guide especially in spring & autumn when temperatures change rapidly.
