Boiling point: 94.7 °C

  • Water boils at 94.7 °C here, which is 5.3 °C lower than at sea level.
  • Cooking times increase at altitude because water boils at a lower temperature. Pasta, rice, eggs, and other foods simmered in water will need longer to cook.
  • Baking is noticeably affected: leavening gases expand faster and liquids evaporate more quickly. High-altitude baking adjustments (extra flour, less leavener, higher oven temperature) are recommended.
  • Atmospheric pressure at this location is approximately 834.3 hPa.

Next stepUse a food thermometer to confirm doneness rather than relying on boiling as a proxy for 100 °C: water is not at 100 °C here.
