The beginning of October will feel more like summer than autumn.
The National Weather Service is forecasting high temperatures in the 80s for the first several days of the month.
On Tuesday, the first day of October, Philadelphians should expect a high of 80 degrees, the weather service says. And that's expected to be followed by highs of 84 degrees Wednesday, 81 degrees Thursday and Friday, and 80 degrees Saturday.
Those temperatures would be about 10 degrees above normal. However, highs in the low 80s still fall far short of record marks. Record highs for the first week of October fall in the high 80s and 90s.
The week is expected to be mostly sunny, the weather service says, with a small chance of rain this weekend.
Fall-like temperatures return Sunday, with an expected high of 73 degrees.
The last time the temperature reached 80 in Philadelphia was Sept. 21, when the mercury topped out at 80 degrees. Before that, the high had last been in the 80s on Sept. 12, which had a high of 89.
