East vs West
West locations were on average 0.79ºC significantly warmer than Eastern beaches (p<2e-16). However, the effect size of the variance in temperature was quite small (6.7%).
29ºC exceedances
More than two thirds of the total number of days, for all locations combined, exceeded the 29ºC temperature threshold. September had the highest number of days beyond that point (92%), followed by August (85%) and October (73%). Most locations recorder lower temperatures by the end of the season, with November being the coldest month.
Hatchery data
Hatch (81.6%) and nest (84.8%) success rates were both higher in shaded areas, in both hatcheries (H1 and H5). Temperatures were higher in unshaded areas, as values rose until September and then start decreasing. The same trends were observed in the shaded areas. Overall, the sand temperatures measured in H5 were higher than in H1. Lastly, great oscillations were observed in both H5 loggers (H5_SHADE and H5_SUN) during the first half of the season.
Sand plots
No significant difference was observed in the hatching success of wild nests between locations on the east and the west (p>0.05) and the same happened with nest success rates (p>0.05). Mean hatch successes were similar at 66.26% for eastern locations and 67.15% for western locations. Mean nest success rates also follow similar results, having 68.41% for the East and 67.98% for the West.
