Average gasoline prices in Washington state have inched higher compared with last week, reflecting a slight uptick in pump costs as crude oil markets firm and seasonal factors influence fuel demand.

Data from price tracking services show the typical price for regular unleaded in the state rising modestly over the past several days, though the increases remain relatively limited compared with broader national trends.

The rise in Washington’s gas prices has been attributed to a combination of factors, including an uptick in crude oil benchmarks and regional supply constraints that can affect distribution costs.

Experts note that as winter travel picks up in some areas and refinery maintenance continues in others, local markets can experience short-term price fluctuations.

Additionally, global oil market volatility — influenced by broader geopolitical developments and production decisions by major producers — has exerted upward pressure on pump prices in recent weeks.

Despite the recent increase, Washington’s average remains in line with or slightly below some national averages, and analysts expect that prices could stabilise as demand softens later in the season and refinery output remains steady.

Seasonal patterns typically see fuel demand decline after the winter travel peak, which can help moderate prices into the early spring.

Motorists are advised to monitor local station prices, as costs can vary considerably across different regions and cities within the state.

Drivers looking to minimise expenses are encouraged to compare prices at multiple stations and consider filling up during times of day when prices are lowest.

The modest weekly rise highlights the dynamic nature of gasoline markets as they respond to shifts in crude oil prices, supply conditions and consumer demand.
