The combination of high temperatures, humidity, and rain could create discomfort for attendees and participants at the outdoor UFC event. The presence of gnats and mosquitoes may also pose a nuisance, particularly given the event's evening timing and the use of bright lighting. Thunderstorms could lead to potential delays or disruptions, and wet conditions may increase the risk of slips and falls on the event grounds. These factors could impact the overall experience for spectators and fighters alike.
