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](http://openweathermap.org/api/uvi) ### Querying UV index observations Getting the data is easy: ```python 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: ```python uvi_list = mgr.uvindex_forecast_around_coords(lat, lon) ``` ### Querying UV index history As easy as: ```python 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: ```python 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.
