How nice the conditions are for tanning. If the weather is good, the tanabilities are good. The ability to tan. A word used by experienced tanners. These tanners won't care about -20 degrees as long as it's still sun. Tanning from sunset to sundown is very usual. Norwegian vikings are famous for their tanning skills. It's said that sun screen is actually forbidden in Scandinavia, although it's just a rumour.
Wow, have you seen the weather outside!? The tanabilities are great! Yeah, I now man. I've been tanning since sunset. Tell me about it. I tanned in the moon light all night. Think I got a moon burn. Wow, that's hardcore. Yeah, I know, I'm that good!
