July 18, 2025 - WASHINGTON, DC. – In the thick of summer, gas prices are laying low with the national average for a gallon of regular going down one cent from a week ago to $3.16. Pump prices have dipped to match the summer of 2021, the last time seasonal gas prices were this low. Meanwhile, a low-pressure system off the Gulf Coast has the potential – albeit low – to strengthen, and it’s something to watch as it moves westward. This time of year, tropical activity can have an effect on gas prices if there’s damage to refineries or if local flooding affects gasoline distribution or demand.  

Today’s National Average: $3.160 

One Week Ago: $3.172 

One Month Ago: $3.167 

One Year Ago: $3.512
