Hi all--
I logged the first tank of my new HCHII this morning (16 days between fill-ups, sweet) and while doing so found the blank for average temperature. Not knowing how to really figure that besides guessing (I'm sure some out there keep detailed logs, but I can't remember to do that), I went to my favorite weather website,
Weather Underground, to see what I could find.
Turns out there's a nifty little tool there that lets you put in custom dates and it will report the weather averages (including max, min, and mean for highs, lows, and daily mean) and precipitation for your city. Here's how:
1) Go to
www.wunderground.com, enter your ZIP code, and hit enter.
2) When your city comes up, scroll down a little to the "History and Almanac" box.
3) Enter the beginning date of your tank in the drop-downs there and click Go.
4) The history for that date should appear. Below the date entry boxes, click "Custom."
5) Enter the end date of your tank and click Go. (The beginning date should be retained.)
6) There it is -- the weather almanac and history for the entire length of your tank.
I used the Mean Temperature Average, which for my city and tank was 43 degrees F. If you don't drive much at night, I suppose you could use Average Max Temp, but that might require a little correction.
I'll admit, it's a long way to go just to be a little more precise (I had initially guessed 40), but I'm sure there are some eggheads (like me) on this site that will like this. --RN
