Yes, pond liners can withstand hot climates, but some materials are better suited than others. Generally, resistance to high temperatures and UV exposure are the biggest concerns. EPDM and RPE are both good candidates for these conditions.
EPDM, in particular, is known for its exceptional resistance to UV radiation and high temperatures. Specifically, it maintains its flexibility even in hot weather, reducing the risk of stress-related damage. It's a long-lasting choice for ponds in hot climates. In RPE, reinforcing layers add strength, maintaining puncture and tear resistance even in stressful hot environments. While not as impressive as EPDM, RPE also has good resistance to UV degradation. PVC, in contrast, is more susceptible to UV damage and can become brittle with prolonged exposure to intense sunlight and heat.
