Has the climate in Neiafu changed?

Neiafu has warmed about 1°F between 1996 and 2024.

About 0.4°F per decade, measured from Neiafu's official daily weather records, 1996–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Neiafu's warming is broadly in line with other cities across Oceania — 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.

Methodology & sources

Temperature — 1991–2020 normals computed from 24 years of daily observations at Lupepau'u, a weather station, about 8 km from the city centre. The underlying daily records come from NOAA's global station network.
