Already on the upside, gas prices may well see additional increases before the month is out, say analysts, primarily due to the failure of talks over the weekend between the U.S. and Iran to end the conflict between the two countries.
The national average now stands at $4 per gallon, which is almost a dollar more than what was seen in April of 2025.
According to the American Automobile Association’s latest figures, the price increase has been particularly notable in the states of the West, with Arizona now at $4.70 per gallon, Colorado at $3.70, and New Mexico coming in at $3.90.
By far the highest price is now seen in California at $5.80.
Put another way, Arizona has seen an increase of $1.30 in the price of gas in the last month, with Colorado up by just under one dollar, and New Mexico up by $1.23.
An upward swath of states in the Great Plains region is recording prices of between $3.40 and $3.70, while most of the South ranged between $3.40 and $3.70 per gallon.
Notes an AAA dispatch of what has turned out to be an 8 cents national average increase: “The last time the national average reached that point was in early August of 2022.”
Throughout the entirety of 2024, gas prices stayed in the region of $3.50, before dropping towards the end of the year to around $3.10.
According to a tracker maintained by Brown University’s Watson School of International and Public Affairs, drivers in the U.S. have thus far absorbed around $9.1 billion in additional gas prices since the war began on February 28. An overall diesel rise, meanwhile, has represented $8.2 billion in total new spending.
