July 4, 1776 weather history for Philadelphia, Penn.

Happy Independence Day, USA! Our country declared independence from Great Britain and King George the third 247 years ago on this very summer day.

We bet you’re wondering what the weather was like that day. Wonder no more! Here’s what the original colonies and territories were feeling – weather-wise – on that historic day.

Philadelphia is, on average, hot and humid in July. However, the day the Declaration of Independence was signed, it was a comfortable 76 degrees around 1 p.m., thanks to a north wind. This record is from Benjamin Franklin, who recorded the daily weather conditions.

This temperature may have been more comfortable with A.C. and a t-shirt, though. Those participating in the signing of the Declaration wore several layers and a powdered wig to top it off – also, deodorant hadn’t been invented yet.

Just days later, on July 10, 1776, a tropical cyclone was recorded to have hit the Virginia coastline, about 5 hours south of Philadelphia. Although the exact area of landfall is not known, moderate damage was reported in the area by coastal communities. One of the early Revolutionary War battles was affected, and supply ships sunk in the Chesapeake Bay – a setback for the start of the war.

Places all over the U.S. will have celebrations for the July 4th holiday. Check your forecast ahead of time to prepare for those outdoor barbecues, fireworks, boating, and pool parties.
