Has the climate in Ventspils changed?

Ventspils has warmed about 3.8°F between 1971 and 2024.

About 0.7°F per decade, measured from Ventspils's official daily weather records, 1971–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Ventspils's warming is broadly in line with other cities in Latvia — neither unusually fast nor unusually slow.

What has actually changed

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 18 fewer freezing nights a year compared with the 1970s.

When in the year the change shows up

July has warmed the most — about 1.8°F. The warming runs across the whole year, not just one season.

Methodology & sources

Temperature — 1991–2020 normals computed from 25 years of daily observations at Liepaja, a weather station, about 107 km from the city centre. The underlying daily records come from NOAA's global station network.
