You can query the OWM API for current Ultra Violet (UV) intensity data in the surroundings of specific geocoordinates.

Please refer to the official API docs for UV

Querying UV index observations

Getting the data is easy:

from pyowm import OWM
owm = OWM('apikey')
mgr = owm.uvindex_manager()
uvi = mgr.uvindex_around_coords(lat, lon)

The query returns an UV Index value entity instance

Querying UV index forecasts

As easy as:

uvi_list = mgr.uvindex_forecast_around_coords(lat, lon)

Querying UV index history

As easy as:

uvi_history_list = mgr.uvindex_history_around_coords(
    lat, lon,
    datetime.datetime(2017, 8, 1, 0, 0, 0, timezone.utc),
    end=datetime.datetime(2018, 2, 15, 0, 0, 0, timezone.utc))

start and end can be ISO-8601 date strings, unix timestamps or Python datetime objects.

In case end is not provided, then UV historical values will be retrieved dating back to start up to the current timestamp.

UVIndex entity

UVIndex is an entity representing a UV intensity measurement on a certain geopoint. Here are some of the methods:

uvi.get_value()
uvi.get_reference_time()
uvi.get_reception_time()
uvi.get_exposure_risk()

The get_exposure_risk() methods returns a string estimating the risk of harm from unprotected sun exposure if an average adult was exposed to a UV intensity such as the on in this measurement. This is the source mapping for the statement.
