Pasco is a large city located in the southeastern part of the state of
Washington in the vicinity of the border with the state of Oregon.
Pasco is located in Franklin County on the banks of the Columbia River
on the leeward side of the Cascade Mountain Range. Because the city is
located on the leeward side of this mountain range annual
precipitation figures are very low. The cities of Kennewick, Pasco and
Richland form the Tri-Cities. The main sources of income are
agriculture and the food processing industry.
Pasco has a steppe climate characterized by its low annual
precipitation figures. During the winter periods with subzero
temperatures (during the night) are uncommon. During the summer

More climate information
Climate figures are very useful but don’t present a general impression
of the climate and the eventual weather circumstances within a certain
period. The figures don’t always reflect the chance of wintry weather,
extreme heat or hurricanes. That is why we offer useful extra climate
information for each month of the year:
