Measure water temperature without a thermometer by using your hand or elbow. Hold your hand close to the water surface; if it's too hot for a few seconds, it's likely around 104-113°F (40-45°C). Use your elbow for a gentler approach; if it feels warm but not uncomfortable, it's roughly 90-100°F (32-38°C). This method isn't precise but helps gauge temperature ranges effectively.
