Is Morocco running out of rain?
Not exactly. It's getting hotter.
I analysed 34 rainy seasons (1991–2025) across a grid of 62 points covering all of Morocco, then tested which changes are real and which could be chance.
The wet years stopped.
Each bar is one rainy season (September to August), as a share of the 34-season average.
"Very wet" = 25% or more above average. Seasons are matched to all 62 grid points.
The centre lost the most.
Average rain per season in 2015–2025, compared with 1991–2015, at each grid point. Regions are weighted by how much rain they normally get, because that's where Morocco's water comes from.
Tap a dot to see that area's rainfall before and after 2015. Bigger dot = wetter area.
The thirsty air.
Evaporation demand is how much water the air would pull out of soil, plants and reservoirs if it could. Hotter, drier air pulls harder, so the same rain goes less far.
Rain decides the harvest.
Each dot is one season: national rain against the cereal yield of the harvest that followed.
Below the line, like 2020: the rain came late, and January–March heat hurt the crops (FAO). Totals hide timing.
What the data can and can't prove.
A p-value is the chance of seeing a trend this strong if nothing were really changing. Below 0.05 counts as statistically significant.
