Remarkably, yes—the water remains hot. The lagoon holds 9 million liters of water, and geothermal energy provides a constant heat input. Snow and sleet do not cool a 38°C body of water quickly. In fact, the contrast between the steaming hot water and the freezing winter air creates a spectacular fog effect.
