Min/max temperature in current weather API and forecast API

Please, do not confuse min/max parameters in current weather API and forecast API. In current weather API temp_min and temp_max are optional parameters mean min / max temperature in the city at the current moment to see deviation from current temp just for your reference. For large cities and megalopolises geographically expanded it might be applicable. In most cases both temp_min and temp_max parameters have the same volume as 'temp'. Please, use temp_min and temp_max parameters in current weather API optionally.

Example of current weather API respond:

"main":{
"temp":306.15, //current temperature
"pressure":1013,
"humidity":44,
"temp_min":306, //min current temperature in the city
"temp_max":306 //max current temperature in the city
},

For comparison look at example of daily forecast weather API respond:

"dt":1406080800,
"temp":{
        "day":297.77,  //daily averaged temperature
        "min":293.52, //daily min temperature
        "max":297.77, //daily max temperature
        "night":293.52, //night temperature
        "eve":297.77, //evening temperature
        "morn":297.77}, //morning temperature

Format

Description:

JSON format is used by default. To get data in XML or HTML formats just set up mode = xml or html.

Parameters:

mode - possible values are xml and html. If mode parameter is empty the format is JSON by default.

Examples of API calls:

JSON api.openweathermap.org/data/2.5/weather?q=London

XML api.openweathermap.org/data/2.5/weather?q=London&mode=xml

HTML api.openweathermap.org/data/2.5/weather?q=London&mode=html

Search accuracy

Description:

You can use our geocoding system to find cities by name, country, zip-code or geographic coordinates. You can call also by part of the city name. To make the result more accurate just put the city name and country divided by comma.

To set the accuracy level either use the 'accurate' or 'like' type parameter. 'accurate' returns exact match values. 'like' returns results by searching for that substring.

Call API by city ID instead of city name, city coordinates or zip code. In this case you get precise respond exactly for your city.

Parameters:

like close result

accurate accurate result

Examples of API calls:

Like api.openweathermap.org/data/2.5/find?q=London&type=like&mode=xml

Accurate api.openweathermap.org/data/2.5/find?q=London&type=accurate&mode=xml

Units format

Description:

Standard, metric, and imperial units are available.

Parameters:

units metric, imperial. When you do not use units parameter, format is Standard by default.

Temperature is available in Fahrenheit, Celsius and Kelvin units.

For temperature in Fahrenheit use units=imperial
For temperature in Celsius use units=metric
Temperature in Kelvin is used by default, no need to use units parameter in API call
