I'm curious, how do they average for the whole year? Is it monthly averages that they average for the year? Is it daily data that is averaged for the whole year?
Whilst in theory they'd be the same in practice the former could be more affected by rounding errors than the latter.
There might also be the oddity that the daily "average" is that of the highest and lowest recorded on a specific "day" whereas the the other "averages" are arithmetic means. The possible complication with "day" is that differences between conventional "local time" and local time according the longitude can vary greatly.
Another reason why raw data (and metadata) can be so important...
