Which Apple Watch Models Measure Temperature?

Only select models from Series 8 onwards include temperature sensors:

• Apple Watch Series 8
• Apple Watch Series 9
• Apple Watch Ultra
• Apple Watch Ultra 2
• Apple Watch Series 10

The SE (including 2024) and models before Series 8, like Series 7, do not measure temperature. The feature debuted with Series 8 in September 2022. Customise your Series 10.

How Does Temperature Measurement Work?

Infrared Sensors

These watches use dual-sensor technology: one sensor on the back touches your skin, while another under the display measures ambient temperature.

Nighttime Measurements

Temperature is measured during sleep with Sleep Mode enabled, analyzed via the Health app on your iPhone.

Tracking Changes

Rather than absolute values, the watch tracks deviations from your baseline, useful for:

• Predicting ovulation
• Detecting early illness signs
• Assessing sleep quality

Why Don’t All Apple Watches Measure Temperature?

Cost-Saving in SE Models

The SE series, including the 2024 model, is budget-focused, omitting advanced sensors like temperature to keep costs low.

Hardware Limitations in Older Models

Pre-Series 8 models lack the necessary hardware and software algorithms for accurate temperature tracking.
