About 0.2°F per decade, measured from Arrecife's official daily weather records, 1973–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Arrecife's climate has warmed more slowly than most other cities in Spain.
What has actually changed

Wetter on average
Arrecife's temperature, year by year
Average temperature for each year from 1973 to 2025.
a warmer-than-average year a cooler-than-average year
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.
When in the year the change shows up
How much warmer each month is now than in the 1970s.
Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
May has warmed the most — about 2.0°F. The warming runs across the whole year, not just one season.
Methodology & sources
Temperature — 1991–2020 normals computed from 30 years of daily observations at Lanzarote/aeropuerto, a weather station, about 5 km from the city centre. The underlying daily records come from NOAA's global station network.
