Note: this article applies to Cyclers using the app with a basal thermometer. If you use a wearable device, please refer to the Oura or Apple Watch sections of Cyclerpedia.
Weather changes will not affect your basal body temperature as your body is very good at maintaining its optimal temperature You can continue measuring as usual even if the temperature increases or decreases due to seasonal changes.
However, our best advice is to trust your judgment and always exclude your temperature if you feel like something is different.
If you're experiencing a significant, sudden increase in outdoor temperatures, for example, in the event of a heatwave or when traveling to a very different climate than your live, then we recommend that you continue measuring to keep up the habit but exclude the temperature the very first morning if you're feeling different because of the weather. After the first morning, you can continue logging your temperature as usual.
