Burrage (1973) states "The body temperatures of active Chamaeleo namaquensis are remarkably stable, despite the varied environmental temperatures of the Namib Desert. On foggy mornings the substrate temperature was as low as 8,0 C; but on clear, sunny days the substrate temperature reached 67,0 C. Of 351 active C. namaquensis body temperatures recorded in the field, the overall range was 14,0-39.7 C; mean 28,7 C; median 28,8 C." He goes on to state that "Field records (N=18) of C. namaquensis at rest ranged from (Coastal N=11) 7,0-13,0 C (mean=10,6 C), and (Inland N=7) 9,0-16,0 C (mean=12,3 C) and were about that of the substrate."
