What time is the hottest time of the day?

The poll had been conducted by 2JJJ in Sydney starting in the 1980s, before Triple J became a national broadcaster. It was originally called the Hot 100 and ran on New Year's Day. The Brisbane independent radio Station 4ZZZ had run the survey under the same name and on the same day since 1977 and owned the rights to the name Hot 100. Triple J was legally required to change the name of its annual survey.
