California's Seasons: A Year-Round Guide (Since I Can't Check Today's Date)

As an AI, I don't have real-time data — but California's seasonal patterns are reliable enough to plan by:

☀️ Summer (June–September)

• Coast (SF, LA, SD): 18–24°C (65–75°F), foggy mornings (June Gloom), sunny afternoons.
• Inland valleys (Sacramento, Fresno): 32–40°C (90–104°F), dry.
• Deserts (Palm Springs, Death Valley): 40–50°C+ (104–122°F).
• Mountains: Thunderstorms, wildfire risk.

🍂 Fall (October–November)

• Best weather statewide: warm days, cool nights, low humidity.
• Harvest season (wine, apples, olives).
• Santa Ana winds (SoCal) — fire danger.

🌧️ Winter (December–March)

• Coast: 10–18°C (50–65°F), rainy periods.
• Sierra Nevada: Heavy snow (ski season: Nov–Apr).
• Deserts: Pleasant days (20°C/68°F), cold nights.
• Atmospheric rivers can bring flooding.

🌸 Spring (April–May)

• Wildflower blooms (Carrizo Plain, Antelope Valley, Death Valley super blooms).
• Green hills, moderate temps — prime hiking/camping.
• Late snowpack melt feeds rivers.

Microclimate Rule

Drive 30 minutes, change seasons. Always check weather.gov or AccuWeather for your exact destination.
