Step 1: Swimming and Temperature Guidelines
Water temperature is critical for swimmer comfort and safety. International organizations like the International Swimming Federation (FINA) set minimum temperatures for competitive swimming. Step 2: Recommended Minimum Temperature
FINA mandates that water temperature for swimming competitions be at least 27° Centigrade. Lower temperatures can cause discomfort, impacting performance and raising hypothermia risk. Step 3: Final Answer
Consequently, swimming water temperature must not fall below 27° Centigrade.
