Reno weather in December

Forum posters describe early December as generally milder with a lower chance of heavy snow than later in the month, with overnight lows commonly below -6C and daytime highs around 4C - genuinely cold but not yet at the season's snowiest. Posters are consistent that December is a real transition month between fall and winter, capable of a warm, snow-free day or a genuine snowstorm, though any snow that does fall this early often doesn't stick around long since the ground is still relatively warm. Posters note the heaviest natural snowfall typically arrives in January and February rather than December. Posters consistently recommend checking the forecast just a few days out rather than planning around typical-December expectations, and flag that the highway can close entirely during a heavy snow event, with chains or 4WD required at times.

Forum posters cite Reno's average March high around 58F with an average low around 34F, only a few degrees warmer than typical February, and describe conditions as capable of rain, snow, or sun depending on cloud cover - sunny but cold on a clear day. Posters flag March as having brought some of the heaviest precipitation of the year in recent years, with genuinely wide swings possible: one visitor hit heavy snow March 19-21, while other years saw fairly typical spring weather during the same window. Posters generally describe roads as clear and dry most years, though warn that an incoming storm could still require tire chains for anyone driving up toward Tahoe. Posters generally recommend flexible plans and a range of clothing options for a March visit to Reno.

Forum regulars describe a typical September as lows in the mid-40sF and highs in the low 80sF, sunny with little rain - but they're quick to add the month is a real wildcard, with year-to-year swings from upper-80s/90s heat to actual snow flurries as the seasons turn over. A roughly 40-degree day-to-night temperature drop is treated as completely normal, so a puffy or lightweight jacket for evenings is standard advice alongside daytime layers. The other September-specific consideration regulars raise: California wildfire smoke can drift into the Reno valley later in the month, so some suggest visiting in early June (before fire season) as the safer alternative if that's a concern.
