If you’re wondering whether your Apple Watch can take your temperature, the answer is not quite straightforward. Let’s delve into what the Apple Watch can do in terms of temperature measurement and how it applies to health tracking.

1. The Basics of Apple Watch and Temperature

The Apple Watch cannot take your temperature in the traditional sense. Unlike a thermometer, which provides instant temperature readings, the Apple Watch functions differently. It measures fluctuations in baseline temperature readings, which are more about noticing trends over time rather than providing on-the-spot temperature data​​.

2. Temperature Tracking on the Apple Watch

The latest models, such as the Apple Watch Series 8+ and Ultra, equipped with watchOS 9+, offer temperature sensing features. However, this doesn’t mean they can measure your body temperature like a conventional thermometer. Instead, they track changes in skin and body temperature over time, which can be useful for various health-related insights​​.

3. Understanding Baseline Temperature Measurements

The Apple Watch calculates a baseline figure of your temperature as it tracks your sleep. Then, it monitors how this baseline changes over time. This method is about observing deviations from your normal temperature pattern rather than providing specific temperature readings​​.

4. Limitations of Wrist-Based Temperature Sensing

Since the Apple Watch is worn on the wrist, it’s not in an ideal position to reliably measure body temperature. The wrist is a bodily extremity, which makes it difficult to get an accurate reading of core body temperature, especially for detecting fever​​.

5. Sleep Tracking and Temperature Analysis

To make use of the temperature sensing feature, you need to set up sleep tracking on your Apple Watch. By wearing it overnight, the watch can analyze your sleeping temperature and identify any significant fluctuations from your normal baseline​​.

6. Practical Applications of Temperature Tracking

The temperature tracking feature of the Apple Watch is particularly useful for women tracking their menstrual cycles. It can help predict ovulation stages based on temperature fluctuations. Additionally, monitoring temperature changes can provide insights into sleep quality​​.

7. Why the Apple Watch Doesn’t Function as a Thermometer

The Apple Watch’s design and positioning make it unsuitable for functions like a traditional thermometer. Its purpose is more aligned with tracking health trends over time, rather than providing immediate medical measurements.

8. Health Insights Beyond Temperature

While the Apple Watch doesn’t offer on-demand temperature readings, it excels in other areas of health monitoring. It can track heart rate, activity levels, and other metrics that are crucial for maintaining a healthy lifestyle.

9. Future Prospects of Temperature Sensing in Wearables

As technology evolves, we might see more advanced temperature sensing capabilities in wearable devices like the Apple Watch. These advancements could potentially offer more precise and diverse health monitoring features.

10. Making the Most of Your Apple Watch

While waiting for potential updates, it’s important to utilize the existing health tracking features of the Apple Watch. Understanding its capabilities and limitations can help you make the most of this sophisticated device.


In summary, the Apple Watch, particularly in its latest iterations, offers a form of temperature tracking. However, it does not function as a traditional thermometer and is not suitable for on-demand temperature measurements. Its strength lies in monitoring temperature trends over time, providing valuable health insights, particularly for sleep and menstrual cycle tracking.


  1. Can the Apple Watch Series 8 take your temperature like a thermometer? No, it cannot. The Apple Watch Series 8 tracks temperature trends over time but does not function as a traditional thermometer.
  2. What is the purpose of temperature tracking on the Apple Watch? The temperature tracking feature on the Apple Watch is primarily used to monitor sleep quality and predict ovulation stages by observing temperature fluctuations.
  3. Is the Apple Watch good for detecting fever? No, the Apple Watch is not designed to detect fever as it does not provide immediate or accurate core body temperature readings.
  4. How does the Apple Watch track temperature? The Apple Watch tracks temperature by analyzing sleep temperature over time and noting any deviations from the baseline temperature.
  5. Will future Apple Watches be able to take accurate temperature readings? While future advancements may improve temperature sensing capabilities, there is currently no indication that upcoming models will function as traditional thermometers.
