Oops, my "misteak"; the table shown above is for
Marquette, not Houghton!
Apparently they don't archive the data reported by the ASOS station at Houghton beyond the three days history shown
here (Drat! I coulda sworn they did!). (Click on the
3 Day History: link in the
Current Conditions section.)
Here's a link to the
Marquette Climate Records.
I used the
Preliminary Monthly Climate Data (CF6) product for June, July, August & September, but you could find the monthly totals in the
Monthly Weather Summary (CLM) also.
It looks like MQT NWS has changed their menus, I can't see where the Co-op observer records are hiding now, like for Phoenix Farms, etc.!
Another option for Houghton would be this Weather Underground page:
KCMX. You'd have to click on the
monthly tab then change the date to the last day of each month, then scroll down for the monthly totals. Tedious!
