Gas prices hit their highest level this year as heat hampers refineries

The rising cost of oil and refineries dialing back production during the summer heat have driven gas prices to their highest levels in nine months. The average price for a gallon of regular-grade gas in the United States reached $3.80 on Wednesday, 26 cents more compared with a month ago, according to data from AAA. It is the highest level since November, though still lower than the peak average of $5 in June 2022.
