Weather extremes
How extreme does Cayenne's weather get?
The hottest, coldest, wettest and snowiest days Cayenne has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Cayenne has recorded — each shown against what a normal day that time of year looks like.
That is about 9°F hotter than a normal October afternoon in Cayenne (typical high near 91°F).
The three most extreme on record
About 10°F colder than a normal December night in Cayenne (typical low near 74°F).
The three most extreme on record
About 43% of a typical April's rain in a single day (Cayenne averages roughly 17.4 in across the month).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Cayenne's record heat sits well above even a hot day for the season — October's 100°F is about 9°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.
