I've enjoyed reading this thread, and the topic of dew points came up in line last
night when I was dancing in North Whitefield, ME - where there was zero evaporative
cooling going on. Steam bath contras. Wowee! The grass outdoors and the cool basement
were well-populated during the break. But my, what a fun night.

Subject: Re: [Organizers] When to cancel dance?
Wow, what a idea — canceling due to heat! Here in the frigid north, we mostly have to
worry about canceling because of snowstorms or ice storms. Guess we all have our own
extreme weather to worry about.
I'm attaching the cancelation procedure that our organizing group came up with a
couple years ago. The short version is that the person responsible for opening the hall
that night makes the call about weather safety by Saturday morning, with help from other
committee members if needed. We've only had to implement this once, and it was a
morning of many phone calls between band members, committee members, caller, etc. (some of
the band members were willing to drive through the snow and ice, the caller and other band
members weren't, so it was tricky), and a pretty heart-wrenching decision overall.
We've maybe canceled two dances in 15 or 20 years.
For what it's worth, we set up our fans so that some of them suck air in and others
blow air out, to keep the airflow moving as much as we can. (We have 3 or 4 box fans in
the windows on on each side of the hall, other windows and all the doors open, overhead
fan on, extra fans for the stage and band.) I would guess that we often dance in 80+
degree heat with 80% or 90% humidity in the summer. Dancers are good about drinking water,
sitting outside or in the basement to cool down, or going for a dip in the local swimming
hole after the dance! (I like your popsicle and ice policy, Concord...)
Good luck,DanaMontpelier, VT

I don’t understand the principle behind having the
fans blow air into the
hall. Are you not just adding the hot outside air into
an already hot room?
By blowing the air out the air movement will draw
cooler air from the
basement, or other cooler areas, into the main hall.
The goal is to move as much air through the hall as possible, since
the outside air is cooler than the inside, and the dancers are
constantly heating up the inside air. There's not much cool air to
draw from other parts of this building.
