Wind averages 6 mph but can spike to 18 mph, typically rising by mid-afternoon as thermal currents lift off surrounding peaks. Morning calm precedes wind, making early arrival essential for stable conditions. Temperature hovers around 42 degrees across the rolling 30-day average, climbing into the 50s only late in season.
Over the last 30 days, Westfall averaged a NoGo Score of 16 with an average wind of 6 mph and temperatures near 42 degrees Fahrenheit. The score ranged from 7 to 55, reflecting the station's volatility between settled mornings and windy afternoons.

About Westfall Forest Service Station
Westfall Forest Service Station is a visitor center and information hub at 4,872 feet elevation in the Yosemite corridor of the High Sierra. Access is via Highway 120, the main eastern approach to Yosemite National Park; the station serves travelers crossing the Sierra and those exploring the surrounding national forest. The location anchors the transition zone between lower foothills and high-elevation plateau, positioned to intercept traffic on the primary east-west mountain crossing. Gateway towns include Lee Vining to the east and Groveland to the west, each 45 to 60 minutes away by car.
Weather and crowds at Westfall show strong diurnal and seasonal patterns. The rolling 30-day average temperature sits at 42 degrees, with extremes ranging from 31 degrees (winter nights) to 58 degrees (warm afternoons in early summer). Wind averages 6 mph but regularly peaks at 18 mph in the afternoon; morning hours are calmer and more predictable. Crowding averages a low 10 on the rolling 30-day metric, reflecting the station's role as a rest stop rather than a destination. Spring and early summer see quickening traffic as Highway 120 clears of snow and Yosemite visitation climbs; late September and early October offer the quietest, most stable conditions before autumn storms arrive.
Westfall suits travelers stopping for information, maps, or brief respite during a long mountain drive. It works well for those timing a Yosemite approach or exploring the eastern Sierra backcountry without committing to the park itself. Experienced visitors plan visits in early morning or late afternoon to avoid the 10 a.m. to 3 p.m. wind window. Parking is typically ample given low baseline crowds. Bring layers; temperature can swing 15 to 20 degrees between early morning and mid-afternoon. Smoke from regional fires (common in late summer) can reduce visibility at this elevation, though the site itself sits outside the park's fire management zone.
Nearby alternatives include Lee Vining, a lakeside town on the eastern base with more amenities and slower afternoon wind than high-elevation passes. Yosemite National Park proper lies 30 to 45 minutes west via Highway 120; conditions in the park valley floor are typically warmer by 10 to 15 degrees and calmer in wind, but crowding is orders of magnitude higher. Tioga Lake and Tenaya Lake offer alpine lake access on either side of the pass, with colder temperatures and more exposed wind than Westfall. For visitors seeking a quieter High Sierra stop with reliable services, Westfall compares favourably on crowd metrics but demands early-morning discipline on windy days.
