Sand temperatures at Zeelandia Beach vary from 31.9–33.3 °C in peak nesting season14. Values represent the difference between a source location (rows) and a new location (columns). Column and row headings represent beach location (O = Oranjebaai Beach; Z = Zeelandia Beach) and treatment (S = shading by palm leaves; C = control). Values in brackets are the standard errors (n = 20).
