Charleston, South Carolina – Gas prices in South Carolina have observed a slight increase over the past week, now averaging $2.74 per gallon. This marks an increase of 2.1 cents since last week, influenced largely by recent weather-related disruptions that took a significant refinery offline in Indiana.

The refinery shutdown has caused notable hikes in gas prices across several states, including Ohio, Wisconsin, and Michigan. In contrast, the national average for gasoline has seen a decline of 4.8 cents compared to one month ago and is currently 16 cents less than this time last year.

As of Monday morning, the cheapest gas available in the Lowcountry can be found in Moncks Corner, priced at $2.55 per gallon, while prices in South Carolina range from $2.43 to $3.89, reflecting a substantial price gap of $1.46.

Despite this recent uptick, the state still experienced a drop of 11 cents per gallon in the previous week, reducing the average price to $2.72. Compared to a month ago, current gas prices now stand 1.6 cents higher, yet they remain 47.8 cents lower than in the previous year. The most affordable gas in the state was recorded at $2.41 over the weekend, whereas the most expensive fuel was priced at $3.54.

In the Lowcountry, Summerville Parker’s has the least expensive gas at $2.49 per gallon available this past weekend. Across the country, nearly every state saw a decline in average gas prices for the second consecutive week, which is notable, especially with the national average hitting its lowest points since 2020 during the Independence Day period.

The national average price for diesel fuel has also seen a slight decrease of 2 cents, now averaging $3.65. Overall, the national gas average is reported to have diminished by 5.3 cents in the past week, standing at $3.09 per gallon, which goes down as 1.1 cents lower than a month ago and 37.4 cents lower compared to last year.

Energy analysts from GasBuddy suggest that if international conditions remain stable, it is possible that gas prices could dip below $3 per gallon later this summer. Nationwide, the price of diesel fuel is currently $3.644 per gallon, experiencing a decrease of 3.2 cents this week.
