WHYY<\/a>, with the average temperature from June through August reaching 78.8 degrees Fahrenheit, matching the third-warmest summer recorded in the city’s history.<\/p>\nThe National Weather Service reported that temperatures climbed above 90 degrees on 40 days so far this year, well beyond the city’s historical average of roughly 30 such days annually.<\/p>\n
The hottest stretch came in early July, when temperatures surpassed 100 degrees for three consecutive days.<\/p>\n
Above-Normal Heat Through the Season<\/p>\n
Sarah Johnson, a warning coordination meteorologist at the National Weather Service, told WHYY that Philadelphia was well above normal for the season overall.<\/p>\n
Philadelphia’s all-time hottest summer remains 2010, when the average reached 79.6 degrees.<\/p>\n
This summer was not an isolated local anomaly. South Florida similarly experienced one of its hottest summers on record, CBS News Miami reported, describing the season there in two words: hot and dry.<\/p>\n
What Drove the Temperatures<\/p>\n
Gabriel Vecchi, a professor of geosciences at Princeton University who specializes in climate science, told WHYY that both large-scale global warming and smaller, unpredictable weather patterns contributed to the historically warm conditions in Philadelphia.<\/p>\n
He said rising global temperatures increase the likelihood of extreme heat, but that the specific setup of storm patterns this season also played a role.<\/p>\n
Human-caused climate change has been pushing overall temperatures higher, raising the probability of dangerous heat events across the region.<\/p>\n
El Ni\u00f1o and What Comes Next<\/p>\n
Johnson noted that a strong El Ni\u00f1o tends to have a more limited effect on mid-Atlantic temperatures but does suppress tropical storm activity in the Atlantic basin.<\/p>\n
Forecasters expect the El Ni\u00f1o pattern to push global temperatures to new record highs in 2027, according to WHYY.<\/p>\n
For Northeast Philadelphia residents, the summer’s toll was measurable. The city recorded a third of its 90-degree days above the long-run average.
