Humidity Is Different Between Saturday and Sunday

On weekend tournaments, Saturdays are more humid and hot because there are more people in the pool room. 

Players tend to need gloves and powder more on Saturdays than Sundays of a weekend pool tournament, because by Sunday the field is whittled down to about the top quarter, and so less people, less humid, less need for powder or using a glove.

As a Tournament Director, we of course notice the same thing.  On Saturdays we plan to wear short-sleeved shirts (females) and light in weight.  On Sundays, we bring back-up sweaters, lol.  The temperature difference is truly amazing from Saturday to Sunday.

One player remarked at the last tourney he uses more powder on Saturdays because it's so much more humid that day of the weekend due to the number of people in the pool room. 

Preparation is key!
