Weather & Seasonal Considerations
Complete seasonal guide with temperature ranges, precipitation patterns, best times to visit, and month-by-month riding conditions at Hungry Valley's varying elevations
Hungry Valley's weather is defined by its dramatic elevation changes—ranging from 3,000 to nearly 6,000 feet—creating distinct microclimates throughout the 19,000-acre park. Understanding these seasonal patterns and temperature variations is essential for planning the perfect riding adventure.
From scorching summer heat exceeding 100°F to occasional winter snowfalls, Hungry Valley experiences true four-season weather. This chapter helps you choose the ideal time for your visit and prepare for the conditions you'll encounter.
Climate Overview & Elevation Effects
Hungry Valley sits in the Tejon Pass north of Los Angeles, experiencing a semi-arid mountain climate characterized by hot, dry summers and cool, occasionally snowy winters. The park's location at the junction of the San Andreas and San Gabriel faults creates the varied topography that influences local weather patterns.
Key Climate Statistics
Annual Averages (Based on Gorman Data)
- Average annual temperature: 56.9°F (13.8°C)
- Annual precipitation: 13.5 inches (344mm)
- Annual snowfall: 13.7 inches over approximately 10 days
- Rainfall days per year: 44 days
- Average humidity: 34-57% depending on season
- Prevailing winds: Variable, strongest in April (6.7 mph average)
How Elevation Affects Weather
The 3,000-foot elevation difference across the park creates significant weather variations:
Lower Elevations (3,000-4,000 ft)
- Warmer temperatures year-round
- Less snow accumulation
- Drier conditions
- Longer riding season
- More dust in summer
Upper Elevations (5,000-6,000 ft)
- Cooler by 10-15°F
- More snow in winter
- Increased precipitation
- Shorter riding season
- Better summer riding (cooler)
Temperature Rule of Thumb
For every 1,000 feet of elevation gain, expect temperatures to drop approximately 3-5°F. If it's 90°F at the park entrance (3,000 ft), trails at 6,000 feet could be a comfortable 75-80°F—a significant difference for summer riding comfort.
Season-by-Season Guide
Hungry Valley experiences four distinct seasons, each offering unique riding conditions and challenges.
Spring (March - May)
PRIME RIDING SEASON
Temperature Range: Daytime highs 65-80°F, nighttime lows 35-50°F (can drop below freezing)
Conditions: Mild temperatures, occasional rain showers, wildflower blooms (April-May)
Why Spring is Excellent:
- Perfect riding temperatures — Not too hot, not too cold
- Occasional rain improves traction — Reduces dust, firms up trails
- Beautiful scenery — Green hillsides, wildflowers in bloom
- Moderate crowds — Less busy than summer, good campsite availability
- Longer days — More daylight for extended rides
Spring Challenges:
- Nighttime temperatures can drop below freezing — Bring warm sleeping gear
- Unpredictable weather — Be prepared for rain
- Muddy trails after rainfall — Some trails may be temporarily soft
- Early spring (March) can still have snow at highest elevations
Summer (June - August)
HOT & CHALLENGING
Temperature Range: Daytime highs 90-100°F+, nighttime lows 60-70°F
Conditions: Hot, dry, dusty, minimal rainfall, intense sun exposure
Summer Positives:
- Longest days of the year — Maximum daylight for riding
- Warm camping nights — No need for heavy sleeping bags
- Consistent weather — Rarely rains, easy to plan
- Higher elevations are pleasant — 5,000-6,000 ft trails can be comfortable
Summer Challenges:
- Extreme heat — Temperatures regularly exceed 100°F at lower elevations
- Heat illness risk — Serious danger of heat exhaustion and heat stroke. For heat illness symptoms and emergency procedures, see our Safety, Emergency & First Aid chapter.
- Heavy dust — Dry conditions create dusty trail surfaces
- Increased water needs — Bring 2-3x normal water supply
- No shade — Limited natural shade throughout park
- Peak crowds — Busiest season, campgrounds can fill up
Summer Strategy
Start rides at dawn (5-6am), finish by 11am before peak heat. Ride higher elevation trails. Take extended midday breaks in shade. Resume evening rides after 5pm when temperatures drop.
Fall (September - November)
ABSOLUTE BEST SEASON
Temperature Range: Daytime highs 65-85°F, nighttime lows 40-55°F (November can freeze)

- Popular season for events and organized rides
Winter (December - February)
Variable Conditions — Advanced Planning Required
Temperature Range: Daytime highs 50-60°F, nighttime lows 30-40°F (often below freezing)
