How do you quantify conditions?

Lighthearted topic of the day:

What metric do you use to quantify whether conditions will be good? I tend to look at the dewpoint, since it blends both humidity and temperature, and find the best conditions when the dewpoint is mid-20s to low-30s. That said, I'm in the humid land of the Northeast, so don't have to consider things like desert conditions where the dewpoint might be in the 20s while it's 80 degrees.

I've heard of folks pitching the "sendex" which I guess is 2*DewPoint+Humidity-MinTemp but that doesn't make any sense to me given that the units don't align...it can't have any real physical basis.

Curious if others have a metric they prefer to the dewpoint and what they consider the optimal range for their skin; I'm particularly curious if anyone scientifically-minded has a take that's grounded in defensible math, but I'm open to all opinions.

The only time we get dew points that low is in the dead of winter, currently the dewpoint is 60 at our place here in Va. 

For me it depends on the time of year as to what I consider optimal temps. Cooler months if it's sunny and above mid 40s we're good to go. Summer is a different story all together....

Temps indicate elevation zone, for me and mine. Its subjective.  

"am I off today? Awesome!" 

Low temp AND low dew point.  Like, ambient temps below 50 and at least a 20 degree temp/dewpoint spread.  Think sierra eastside in winter, shelf road in January, Smith in late fall.  I hate humidity and I sweat like a failing comedian so, it’s a package deal if I want dry, crispy fingertips.  It’s all subjective.  There’s no math.

For me.

Dew point, wind, wind direction. Temperature matter but is way overrated. I'd rather have warm dry and breezy, than cold damp and still.

We have an east coast maritime influenced climate so actually the wind direction more or less determines everything else.

Polar onshore is the worst, cold, damp, wet. Tropical or temperate onshore is climable, can be ok if the sea breeze is strong enough. Pretty damp though.

Polar offshore (winter cold front winds) usually gives the best conditions on the lee downslope of the ranges. A high likelihood of wintery misery though.

Temperate offshore is hot and dry, off the interior desert. Wildfire weather. Can be surprisingly good but of course it's often far too hot.

Conditions are always bad.

That way - 

1. I have an excuse when I punt

2. If it's a miracle day and I send, it comes with greater glory

Good conditions - 30-50 degrees + sun, or 50-70 degrees + shade. Humidity is rarely a factor in CO, and good conditions can be found every month of the year if you pick your days and elevation

If it's below 90º I'm game.

Ha!  Same.  Chuffers like me don't worry about such nuanced things as "conditions".
