Jim,
I’m not sure if this has been covered here before, but here are a few links to Government climate data and maps in the US. Microclimate data are represented as well, to a degree limited by the number of stations:
Climate Maps of the United States – Lookup Page [1]
Monthly Station Climate Summaries – By Station [2]
For those interested in wind speeds and patterns across the USA for whatever reason, the map link above can be supplemented with the data for the major population centers [4].
Thanks again for your hard work, – The DFer
JWR Replies: Thanks for sending those links. They are very useful for both assessing the “livability” of various locales. Along with prevailing wind maps (which are useful for radioactive fallout prediction), I consider maps an essential planning tool. I strongly recommend that anyone considering retreat locales should do a climate study first. It is notable that climate and growing season duration are what caused us to rule out areas east of The Great Divide [5] when we went searching for the Rawles Ranch.
