Year of the Records
Posted: 13 Oct 2026 05:30 AM, Views: 863Monday was another very warm October day with a number of locations at or near record high temperatures. With a high of 87°F, Burlington set a new daily record besting the previous record of 86°F set in 1956. The featured chart looks into the year where the present day record lies by day of the year. The dots show the year of the daily record with any ties both plotted. The right side bar charts total up the record counts by decade. The colors represent the age of the record. The upper left panel shows the record daily high temperatures and the lack of recent such records during the summer months is readily apparent. The next panel shows the opposite situation with plenty of record maximum warm low temperatures being recently set over the past few decades and during the summer months. Tuesday will be a bit cooler, but still plenty warm for mid October!
