For a decade ago, the aviation METAR reports (containing temperature and devpoint) were archived on an hourly basis for all significant airports worldwide on a FTP site, unfortunately, I have lost the URL.
Wouldn't it be better to measure your local realtive humidity and then have your cooling system act on that automatically? A wet and dry temperature sensor pair should be enough information to decide - and that way if a front rolls in overnight you don't end up with a damp house.

Find a weather station that's near you on Weather Underground? -->
In my parachuting days I was listening to those on shortwave, I kind of knew when they got around to our airport. Online you can get it here by keying in the four code letters of your airport:
The wee problem: They obviously stopped at KPVF on the evening of June-10 and this service uses the same data that the other NOAA service employs, the one that I was using in the past. All I get is this:
2011/06/10 18:55 KPVF 101855Z AUTO 21008KT 10SM CLR 23/13 A2999 RMK AO1In other words, no METAR from that airport :-(

It leads to the closest airport data (KPVF). That data is a week old and frozen to June-10.

Thanks. If I ever get through the ever-increasing honey-do list I might do this. Realistically in 150-200 years :-)
BTW, did you ever identify who's the electricity hog in your house?

They appear to have stopped METAR updates on June-10 :-(
(which is why I posted)

Yes, if I get around to it I'll do that :-)
But doing it by hand was easy. When wrapping up work for the night I looked at the graph and then before going to bed left the cooler on "cool" or flicked the switch to "vent", depending on that reading.
Controlling it via uC is a piece of cake but only in theory. Reality is you have to switch a 120V circuit that is only accessible above an open water basin, it's all outside, there is no permanent 120V outlet anywhere close outside, and so on.

Thanks, but I can find a humidity graph anywhere, or any graphs.

Yes, it is possible to subscribe to MADIS data via NOAA. That isn't nearly as convenient anymore as the good old web display was but may be the only option left, other than setting up our own hygrometer with 24h logging.

Weather Underground is a little unintuitive to navigate at times, but it's really an incredible resource.
Start here:
Oh yeah, indeed. Shazam! It's a clumsy navigation but works:
Thanks, Joel and John. The humidity reading seems a bit off because I get 75F in and 64F out right now, which equates to 40% while the station on Wunderground shows 53%. Reason may be that it's near the lake.

That's too complicated for Joerg, he'll have all kinds of excuses for it not doing what he wants.
The wundergound page is great... I found a weather station just blocks from me! ...Jim Thompson

I love to cook with wine. Sometimes I even put it in the food.
Have you tried
Good Luck! Rich

The house is for sale, if you're interested in moving... it'd probably even be plenty warm for you! We'll even throw in the chicken coop seen in the webcam photo for free, if you'd like! :-)

Ha1 Your "low" humidity is higher than I've ever seen in AZ except during a thunderstorm. ...Jim Thompson

Same here, except the station is near the lake and seems to show 10-15% higher humidity. But it'll show the trend alright.
You mean the station is on your property? Wow! Next to the chicken coop, are those two dog houses?

Yep, that's our rooftop you see there; the background is surprisingly picturesque.
They're actually covered cat litter boxes... but they work well for broody hens too!
