It is very common for you to notice signs of brumation in the late fall, just before winter (October, November). But for some bearded dragons, brumation starts around June, when it’s winter in Australia, their native habitat. Generally, the timing for brumation depends on the individual dragon, seeing as several factors are considered before this course of action is taken. An interesting rule of thumb is to pay attention to the change in weather, from heat to cold. This, accompanied by other cues can indicate that your beardie is about to take a long deep nap!
