The weather’s not the problem. Highs in the 70s and 80s, nights in the 50s, and barely a whisper of rain — classic Sonoma September. The Harvest Moon on Sept. 7 shines on full bins and long nights. But beneath the glow, growers are staring at a harsh reality: record-low U.S. wine consumption and an oversupplied market mean some grapes won’t get picked at all. Analysts expect as much as 30% of Sonoma’s crop uncontracted, and thousands of acres are slated for removal. It’s a year where quality is stellar but the business feels brutal.

Outdoor cannabis is still weeks away, ripening toward late October—November. September is prime flowering: resin builds, colas swell, and farmers pray for dry skies. A late-September rain can trigger bud rot overnight. Indica strains finish earlier; sativas take their time, stretching deep into Croptober.
