(October 25, 2025) SwampButt Underwear today announced its latest data-driven college football tie in approach to marketing its garments with the release of its Week 9 college football predictions based on the ‘Scale of Sultry,’ a proprietary model developed to measure how weather and humidity effect on-field performance. Through Week 8 the scale was 21-11 using weather as the only measure of game outcome.
The model rates conditions on a 1–10 ‘Sultry Index’ and compares each team’s home-climate adaptation to the forecasted game environment. Teams whose home climates align most closely with game-day conditions receive an advantage.
“Football in the South isn’t just about playbooks and penalties — it’s about whether you can breathe” said Harold Nicoll, APR, developer of the model. “Our Scale of Sultry measures which programs are built for hot, humid dare I say swampy Saturdays.” Predictions highlight LSU’s humid advantage over Texas A&M and Oklahoma’s favorable home conditions against Ole Miss. Full data visualizations and reports are available for media review.
More and Better Data
For Week 9, the ‘scale added information on the average sultry index for each of the two teams playing. The ‘scale index is also carried out to a decimal place making the measurements more accurate. It also added a predicted winner and the confidence each weather and climate-based prediction had. “I used historic climate data for each team and even added a dome/inside scale,” said SwampButt Underwear owner and inventor of the ‘scale. “I used regression analysis that is to make predictions for marketers and even election outcomes.”

“Our premise is simple,” said SwampButt Underwear spokesman Nick Heraldson. “Schools in places where the weather is hottest and most humid are better conditioned than those in more moderate climates. It’s valid enough.”
