Water boils at 100Â°C at standard pressure, no exceptions! However, the water temperature in the kettle is not even. Around the heating elements, the water rapidly reaches 100Â°C, even if the water in the rest of the kettle is cooler.
The most accurate way to ensure the water is boiling is to use a thermometer. At sea level, water boils at (212Â° F; 100Â° C); this temperature decreases at higher altitudes. If you're using a container that holds heat well (like a glass or ceramic one), be careful when you take the water out of the microwave to stir it.
