Mean sand temperatures at nest depths were 31.0 °C, ranging from 29.1 °C to 33.3 °C

Rainfall and spring tides had important cooling effects on incubation temperatures.

Sex ratios of 3 species of sea turtle were female-biased during the past century.

Rising air temperatures will exacerbate the female skew in future populations.

Management strategies will be necessary to prevent localised extinction.
