Basic Examples (4) 

Get the current heat index at your location:

In[1]:=

Out[1]=

Get the heat index in Miami:

In[2]:=

Out[2]=

Specify the desired output as "Temperature":

In[3]:=

Out[3]=

Specify a temperature and humidity instead of a location:

In[4]:=

Out[4]=

Scope (6) 

The output unit, in this case degrees Celsius, is inherited from the input:

In[5]:=

Out[5]=

If the temperature is not explicitly given with the unit, is interpreted as Fahrenheit (95 °F):

In[6]:=

Out[6]=

If the relative humidity is not given as a Quantity, values between zero and one are interpreted as a fraction:

In[7]:=

Out[7]=

Humidity values between one and one hundred are interpreted as a percentage:

In[8]:=

Out[8]=

Create a plot of the heat index as temperature varies for relative humidity fixed at the current value of Cairo. The red point indicates the current temperature:

In[9]:=

Out[9]=

Use "PropertyAssociation" to get the heat index and plot together:

In[10]:=

Out[10]=

Provide a GeoPosition instead of an Entity:

In[11]:=

Out[11]=

Options (2) 

The "ResultUnit" option specifies the temperature unit for the result:

In[12]:=

Out[12]=

Create a plot with the heat index values shown in Celsius:

In[13]:=

Out[13]=

Possible Issues (4) 

Values outside the supported range are inaccurate, and in these cases the result is a TildeTilde object:

In[14]:=

Out[14]=

Sometimes the nearest weather station of a specific location does not have data of air temperature and/or relative humidity:

In[15]:=

Even if the unit of the input temperature is different from Fahrenheit, the x axis in the plot remains in Fahrenheit:

In[16]:=

Out[16]=

For relative humidity values between 0% and 1%, the input must be explicitly given with a percentage unit. Otherwise, in the example below, 12% would be interpreted instead of 0.12%:

In[17]:=

Out[17]=
