Personal Weather Stations (PWS) Current Conditions returns the current conditions observations for the current record.Current record is the last record reported within 60 minutes. If the station has not reported a current conditions in the past 60 minutes, the response will not return an expired observation record (older than 60 minutes); a 'Data Expired' message will be returned instead.

Object containing fields that use a defined unit of measure. The object label is dependent on the units parameter assigned in the request.

"imperial", "metric", "metric_si", "uk_hybrid"

object   imperial: {.....} N
dewpt The temperature which air must be cooled at constant pressure to reach saturation. The Dew Point is also an indirect measure of the humidity of the air. The Dew Point will never exceed the Temperature. When the Dew Point and Temperature are equal, clouds or fog will typically form. The closer the values of Temperature and Dew Point, the higher the relative humidity. integer/decimal

-80 to 100 (°F) or

-62 to 37 (°C)

58 Y
elev Elevation integer/decimal   3094 Y
heatIndex

Heat Index - An apparent temperature. It represents what the air temperature “feels like” on exposed human skin due to the combined effect of warm temperatures and high humidity.

When the temperature is 70°F or higher, the Feels Like value represents the computed Heat Index.

integer/decimal   67 Y
precipRate Rate of precipitation - instantaneous precipitation rate. How much rain would fall if the precipitation intensity did not change for one hour integer/decimal   0.0 Y
precipTotal Accumulated precipitation for today from midnight to present. integer/decimal   0.0 Y
pressure Mean Sea Level Pressure, the equivalent pressure reading at sea level recorded at this station integer/decimal   30.06 Y
temp Temperature in defined unit of measure. integer/decimal   67 Y
windChill

Wind Chill - An apparent temperature. It represents what the air temperature “feels like” on exposed human skin due to the combined effect of the cold temperatures and wind speed.

When the temperature is 61°F or lower the Feels Like value represents the computed Wind Chill so display the Wind Chill value.

integer/decimal   -34 Y
windGust Wind Gust - sudden and temporary variations of the average Wind Speed. The report always shows the maximum wind gust speed recorded during the observation period. It is a required display field if Wind Speed is shown. integer/decimal   56 Y
windSpeed

Wind Speed - The wind is treated as a vector; hence, winds must have direction and magnitude (speed). The wind information reported in the hourly current conditions corresponds to a 10-minute average called the sustained wind speed. Sudden or brief variations in the wind speed are known as “wind gusts” and are reported in a separate data field.

Wind directions are always expressed as ""from whence the wind blows"" meaning that a North wind blows from North to South. If you face North in a North wind the wind is at your face. Face southward and the North wind is at your back.

integer/decimal   56 Y
