The Weather insights shows the following:

Sunrise / Sunset

The upcoming sunrise or sunset, depending on which is next.


If you place the watch into the water (below 10 cm/ 4 inches) you can measure the water temperature. After you take the watch out of the water the temperature is shown for next 30 seconds. This is indicated with a separate temperature icon.


Measuring the water temperature will affect the ascent/descent values as these are pressure based.

Estimated time of arrival (ETA)

If the estimated time of arrival goes past the sunset, it will be shown in red.

Barometric trend and storm alarm

The barometric trend is shown on the bottom of the screen, with current barometric value. The Suunto storm alarm will be given automatically and shown in this view. A storm symbol is shown if the pressure drops 4 hPa (0.12 inHg) or more during a 3-hour period.

Oxygen level

If you are above 2000 m (6 561 ft) you will get a reading on the oxygen % compared to sea level.
