Wanderlust World Wanderlust World Deserts don't experience "summer" in the temperate sense of a warm growing season. Instead, they're defined by extreme aridity and temperature swings that don't follow conventional seasonal patterns.
Deserts can be scorching by day (50°C/122°F+) and freezing by night (below 0°C/32°F) due to lack of humidity and cloud cover. These diurnal swings often exceed seasonal variation. The concept of "summer" implies a predictable warm period—but deserts may have brief, erratic warm spells or year-round heat depending on latitude.
Hot deserts (Sahara, Arabian, Sonoran) have two seasons: a long, extremely hot period and a shorter, milder period. Cold deserts (Gobi, Great Basin, Patagonia) have distinct winters with snow and subzero temperatures. Neither fits the four-season model.
Where deserts have recognizable seasons, they're marked by rain, not temperature. Monsoon deserts (Thar, Sonoran) get a brief wet season. Winter-rain deserts (Mediterranean, Chilean) receive moisture in cooler months. The "season" is when life blooms—often lasting just weeks.
Warming intensifies heatwaves and alters already-unpredictable rainfall. Some deserts are expanding; others see unprecedented flooding. Traditional seasonal knowledge is becoming less reliable for indigenous peoples and ecosystems alike.
So while calendars say "summer," deserts operate on their own climatic rules: water availability drives biology, not the sun's angle.
