Weekly Update: October 2, 2026 at 3:07 PM Pacific Time (a special update regarding events on October 6 only)
General Conditions
Cool, overcast weather a week ago has given way to warmer, sunny skies with temperatures reaching the mid-70s. Fall color has begun to appear in some aspen groves where cold air collects overnight; but we need overnight freezing temperatures for color to develop fully. The Central Sierra Snow Lab web site (https://cssl.berkeley.edu/) has details, but CSSL is recalibrating instrumentation so some data streams may be temporarily unavailable.
Purple Air AQI around the Summit this morning is 5-20 (good air quality). There are no active fires near Donner Summit. USFS rates fire danger in the Truckee Ranger District as “high”; Truckee Fire rates the fire danger as “very high”.
Sunrise/Sunset: Today’s (October) sunrise was at 6:57 AM, about 6 minutes later than a week ago. Sunset will be at 6:43 PM, about 12 minutes earlier than last week. The days are getting shorter — by about 2-1/2 minutes each day; this combined rate will continue into mid-October.
Star Gazing: The “Harvest” Moon was full last Saturday, so evening stargazing will be good for the next couple weeks. The waning Moon is rising several hours after sunset. Venus is the bright star-like object just above the western horizon half an hour after sunset. Saturn is at opposition on October 4 meaning it is at its brightest and is south of overhead at about midnight. Saturn is brighter than most stars, but it doesn’t compare with Venus, Mars, or Jupiter at their brightest. With a pair of good binoculars, you may be able to see Saturn’s rings. As for stars, Cassiopeia looks like a “W” rotated about 90° above the northeastern horizon; the Big Dipper is low to the northwest and oriented just about right to hold water at 10 PM.
Forecast
Conditions on Donner Summit will be unseasonably warm and dry for the next 10 days. The temperature extremes (high/low) on Saturday are forecast to be 78°/45° and they will hold in that vicinity until the following weekend when they will drop to 69°/42°. The highest probability for measurable precipitation in the next two weeks is 8% on October 14; on most days the probability is 0%.
