The highest temperature measured 50°F on the 10th, while the low temperature of -5°F occurred both on the 23rdand on the 27thof the month. Remarkable were the strong temperature variation, with new daily maxima around the 10thand new daily minima around the 25thof the month.

Big Delta reported a mean temperature of -21.4°F in January 2012, which is a very substantial 20.4°F below the long-term mean temperature. The high temperature of the month was observed on the 11that 14°F, while the low temperatures occurred on the 29thwith -50°F. In general, the daily temperature trace is similar to Fairbanks, however, extreme low temperature occurred less frequently, and only on 6 days were temperatures of -40°F or below recorded. As the Alaska Range is much closer to Big Delta than to Fairbanks, wind speeds are higher, and somewhat more mixing with the warmer air above occurs, weakening the surface temperature inversion. No new temperature records were observed.
