Methods of compensating for ambient temperature using temperature sensors, the method comprising: sampling at a first sampling rate, with a processor, first temperature measurements from a first temperature sensor on an on-body sensor. Then determining, with a processor, first ambient-compensated temperatures from the first temperature measurements; and determining, with a processor, final ambient-compensated temperatures by applying a correction gain or factor to the first ambient-compensated temperatures.

A system and method provides a glucose report for determining glycemic risk based on an ambulatory glucose profile of glucose data over a time period, a glucose control assessment based on median and variability of glucose, and indicators of high glucose variability. Time of day periods are shown at which glucose levels can be seen. A median glucose goal and a low glucose line provide coupled with glucose variability provide a view into effects that raising or lowering the median goal would have. Likelihood of low glucose, median glucose compared to goal, and variability of glucose below median provide probabilities based on glucose data. Patterns can be seen and provide guidance for treatment.
