Los Angeles or Marrakesh: which climate?
Los Angeles (United States) has a hot-summer mediterranean climate, whereas Marrakesh (Morocco) has a hot semi-arid climate, according to the Köppen-Geiger classification.
The values compared here are normals computed over 86 complete calendar years, from 1940 to 2025, using ERA5 reanalysis data from the Copernicus programme. The same method and the same period apply to Los Angeles and to Marrakesh.
Marrakesh is warmer than Los Angeles by 1.3 °C in annual average: 18.7 °C against 17.4 °C.
Los Angeles gets more rain than Marrakesh: 352 mm per year against 289 mm.
Marrakesh has warmed by +2.3 °C between 1940 and 2025, against +1.7 °C in Los Angeles. Marrakesh is therefore warming faster than Los Angeles. Both trends are statistically significant.
Los Angeles averages 62 hot days (≥ 30 °C) and 1 frost days per year; Marrakesh averages 114 and 1.

A difference is only reported when it exceeds the resolution of the data. ERA5 is a reanalysis on a grid of about 31 km: two nearby cities often fall in the same cell, and below half a degree you are reading the grid, not the climate.
