Boise Gas Prices Jump 24 Cents to $5.06 Per Gallon

Motorists in Ada County faced a sharp increase at the pump this week, with average gas prices in Boise climbing approximately 24 cents per gallon by September 28. The surge pushed the local average to $5.06 per gallon, marking a significant jump for Treasure Valley drivers already grappling with higher transportation costs.

Boise Fuel Costs Surge

The recent spike represents a broader upward trend for Idaho homeowners and commuters. Current prices in Boise are 50 cents per gallon higher than they were just one month ago. Over the last year, the cost of fuel has risen even more dramatically, sitting $1.57 per gallon above levels recorded twelve months prior.

Statewide figures reflect similar pressure on Idaho taxpayers. The average gas price across Idaho reached $4.98 per gallon, up from $4.83 per gallon the previous week. While Boise prices have climbed higher than the state average, the overall increase adds to monthly budgets for families and small business owners relying on personal vehicles for work and daily errands.

Regional Price Comparisons

Fuel costs in neighboring regions show mixed trends compared to the steady rise in Idaho. In Ogden, Utah, the average price hit $4.91 per gallon, an increase from $4.70 the week before. Meanwhile, Oregon drivers saw a slight reprieve, with prices dropping 2 cents to $5.03 per gallon from $5.05 previously.

Despite the minor dip in Oregon, the broader West Coast market remains volatile. Patrick De Haan noted that while oil holding below $100 per barrel could lead to modest declines for many Americans, the West Coast faces continued pressure with further increases possible.

Impact on Ada County Drivers

For residents of Boise, Meridian, Eagle, and Kuna, the 24-cent weekly jump translates directly into higher expenses. With gas prices remaining well above $5 per gallon in the capital city, the financial burden on local households continues to grow. The data indicates that without a significant shift in regional supply or crude oil pricing, Idaho drivers may see these elevated costs persist through the coming weeks.
