About Deer Valley
Deer Valley Resort sits on the eastern slope of Utah's Wasatch Range immediately above Park City, with lift-served terrain on Bald Mountain reaching a summit of 2,917m (9,570ft) above a base near 2,000m. Known for its skier-only policy, on-mountain service and consistently groomed corduroy, Deer Valley hosted the freestyle skiing events (moguls and aerials) at the 2002 Salt Lake City Winter Olympics and has run World Cup mogul and aerial competitions on the same venues for decades. Its position on the eastern Wasatch catches the same storms that feed the Cottonwood canyons — Pacific fronts that lose much of their moisture climbing the Sierra and Great Basin before encountering the Great Salt Lake, where they pick up a final orographic charge and drop low-density snow on the Wasatch crest. Across 10 winters of ERA5 reanalysis data (2015-2025), Deer Valley averages 342cm (135 inches) of snowfall a year, with the heaviest accumulations concentrated between December and March. This page uses that decade of historical snowfall data to help you find the weeks most likely to deliver fresh powder.
Snowfall patterns over the last decade
Across ERA5 reanalysis snowfall records from 2015 to 2025, Deer Valley averages 342cm (135 inches) of snowfall a year, with the November-through-April ski season delivering about 304cm of that total. January is the heaviest calendar month in the 10-year average at 64.9cm, narrowly ahead of March at 61.2cm, February at 56.8cm and December at 52.9cm — four closely-matched midwinter months. November builds the base at 35.7cm and April tails off at 32.7cm. Ranked by powder probability — the share of weeks with at least 15cm of fresh snow — February leads at 43%, ahead of January at 40%, March at 37%, December at 28% and November at 20%, with April dropping to 14%. The window with both the deepest totals and the highest powder odds is mid-January through mid-March, with February the single most reliable powder month in the record.
Year-to-year variability is large. January snowfall in the 10-year record ranges from 20.5cm in the driest winter to 143.0cm in the wettest — a roughly seven-fold spread on a single calendar month. February swings between 18.3cm and 103.3cm, March between 29.4cm and 126.6cm, and December between 25.0cm and 114.9cm. The relatively high floor on March (every March in the decade cleared 29cm) is the planning sweet spot: the deepest March in the record produced more than four times the snow of the driest, but neither extreme fell below skiable totals. This volatility is why two consecutive seasons can feel completely different at the same week, and why a multi-year baseline is more useful for choosing travel dates than any single-week Deer Valley snow report.
In the context of the Utah resorts tracked here, Deer Valley's 342cm annual average sits between neighbouring Park City (263cm) and the higher Cottonwood resorts. The gap with Park City — directly adjacent and sharing the same Wasatch storm track — is concentrated in midwinter: Deer Valley's January (64.9cm) and February (56.8cm) totals are both meaningfully above Park City's (49.0cm and 42.4cm), and the powder-day probability is higher in every month. The 2,917m summit on Bald Mountain sits roughly 140m below Park City's but the resort's east-facing aspect and a relatively narrow lift-served terrain footprint concentrate the orographic snowfall on the upper sectors. For peak powder probability the late-January through mid-March window concentrates the highest hit rate; for the longest reliable window, the mid-December through late-March stretch has historically delivered at least 50cm a month every season in the record.
Snow & Weather Conditions
We use 10 years of historical data to help you plan — not a live snow report.
Utah's legendary slogan "The Greatest Snow on Earth" is backed by science — the unique lake-effect weather pattern from the Great Salt Lake produces incredibly light, dry powder with low moisture content. Altitude is a key advantage here: the higher you go, the colder and drier conditions become, resulting in dependable accumulations and a snowpack that resists deterioration well into spring. Most winters deliver 6-10 metres of cumulative snow, compressing into a 2-metre-plus base by the middle of the season.
Best Time to Ski
The best time to ski at Deer Valley is February and January, with 56.8cm average snowfall and 43% powder probability. Based on 10 years of historical snowfall data from PowderDays. Season runs November to late April. January and February typically deliver the most consistent powder days.

What Makes It Special
Steep, expert-friendly terrain dominates, from tight tree runs to wide powder-filled bowls. Many resorts offer over 3,000 vertical feet of skiing. Utah resorts are known for easy access from Salt Lake City (often under an hour), friendly locals, and a growing food and craft-drink scene.
"The Greatest Snow on Earth" is Utah's official trademarked tourism slogan. Research from the University of Utah's Department of Atmospheric Sciences confirms that Utah snow averages just 8.5% water content compared to the 12% typical of other regions, making it measurably lighter and drier.
Data Sources & Methodology
All snowfall statistics for Deer Valley are based on 10 years of historical data (2015-2025) from the Open-Meteo Historical Weather API, which provides ERA5 reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF). Daily snowfall totals are queried at Deer Valley's coordinates (40.64, -111.48) and 2,917m elevation, then aggregated into monthly averages, record highs/lows, and powder probability scores. Powder probability represents the chance of receiving 15cm or more of fresh snow in any given week during that month.
