Has the climate in Moses Lake changed?

Moses Lake has warmed about 1.6°F since 1998.

About 0.6°F per decade, measured from Moses Lake's official daily weather records, 1998–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Moses Lake's warming is broadly in line with other cities in United States — neither unusually fast nor unusually slow.

What has actually changed

Each card compares the 1970s (the first ten years of the record) with recent years (the last ten) — the same span the headline and the chart use.

Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.

In day-to-day terms, that long-term shift shows up as about 16 more freezing nights a year and about 9 more days above 90°F compared with the 1970s.

When in the year the change shows up
