They've also got a rather nice API - https://api.met.no/weatherapi/documentation // https://api.met.no/weatherapi/locationforecast/2.0/

In particular, I like the detailed info on clouds:

        <time datatype="forecast" from="2022-09-13T00:00:00Z" to="2022-09-13T00:00:00Z">
            <location altitude="986" latitude="45" longitude="90">
                <temperature id="TTT" unit="celsius" value="8.9"></temperature>
                <windDirection id="dd" deg="353.8" name="N"></windDirection>
                <windSpeed id="ff" mps="10.6" beaufort="5" name="Frisk bris"></windSpeed>
                <humidity unit="percent" value="55.5"></humidity>
                <pressure id="pr" unit="hPa" value="1020.1"></pressure>
                <cloudiness id="NN" percent="78.9"></cloudiness>
                <fog id="FOG" percent="0.0"></fog>
                <lowClouds id="LOW" percent="0.0"></lowClouds>
                <mediumClouds id="MEDIUM" percent="46.9"></mediumClouds>
                <highClouds id="HIGH" percent="64.1"></highClouds>
                <dewpointTemperature id="TD" unit="celsius" value="0.5"></dewpointTemperature>
            </location>
        </time>

The difference e between low, medium, and high clouds is useful for deciding "where may there be a good sunset?" Most other services just offer the general "cloudiness".
