The rainy season varies from desert to desert. Some deserts primarily have a wet summer, others in the winter while some have a brief summer rainy season as well as a brief winter rainy season.
Each desert has its own weather and rainfall statistics but a desert is defined as a region that receives less than 10 inches (250 mm) of precipitation on average per year.

It gets alot a year
A desert is defined as an area that receives less than 10 inches (250 mm) of precipitation per year on average. There are over two dozen major deserts in the world and each has its own climate statistics. Some deserts receive virtually no rain for decades. Others receive up to ten inches per year on average. With a particular location this answer could provide a more specific answer.
Some scientists classify deserts are either hot or cold, others break that down further: Subtropical Desert - Sahara, Great Victorian, Chihuahuan, etc. Cool Coastal Desert - Namib, Atacama, etc. Cold Winter Desert - Gobi, Great Basin, Antarctica, etc.
Whether an area is or is not dessert does not have any effect on the length of the seasons there. Summer and Winter will cover the same time span in a desert as it does for any other area at the same latitude. What is different is the weather in a desert in the summer and the winter. Because deserts are dry, the humidity is very low and cloud cover is less. This leads to wider temperature swings between daytime and nighttime temperatures. During the summer, the temperatures could be brutally hot during the day and yet drop to uncomfortably cold temperatures at night. During the winter it might be only moderately cold during the day but then drop to brutally cold during the night. Depending on the type of desert, Winter may also be the season with the highest precipitation - although being a desert, getting "more" precipitation may still not amount to very much.In broad terms, Summer lasts about 3 months and Winter lasts about 3 months in the desert. If you get to extreme northern latitudes or extreme southern latitudes, the effective Summer and Winter seasons (i.e. months with "summer weather" and months with "winter weather") get longer with shorter Spring and Fall in between, but that is a function of the latitude, not the desert environment. In Antarctica is considered a desert with annual precipitation of only 200 mm (8 inches) along the coast and far less inland. Down in Antarctica it gets closer to being effectively 5 months of Summer and 5 months of Winter.
Extremey hot climates such as the Sahara desert ( equatorial ) or Extremely Cold climates such as Antarctica. The desert part refers to there being no or very little rain fall or liquid water in these places.
the tundra.
desert and tundra tundra doesnt have snowbut desert has the least
I believe it is the tundra. It does get little precipitation, and it is very cold, resulting in the frozen soil.
tropical rain forest
The tundra receives about the same average annual rainfall as a desert.
I think the turndra has the most extreme cold and rarely has precipitation but it's mostly snow, there's also the desert which is cold at night and gets no snow but I would think tundra.
The tundra biome is often called the frozen desert. this is because it gets little rain. But because of the the permanently frozen layer of soil under the ground (permafrost) it stays cooler than the desert biomes because the desert biomes would be very hot under tose huge sand dunes and all of the heat that the deserts are consuming to keep dry.
climate-wet gets 2nd most amount of precipitation per year than in any other biome, aquatic fish live here
Which desert where? "Desert" just means "a region with low precipitation". Most of Antarctica is a desert; it gets pretty darn cold there in the winter.
Very little - much of the high Arctic is technically a desert and gets very little precipitation.
Even though you may think of snow as wet, it is actually ice and the tundra gets little precipitation, causing it to be dry
the wettest desert gets about 10 inches of rainfall a year
