Weather - Get Daily Forecast

Use to get a daily detailed weather forecast for the next 1, 5, 10, 15, 25, or 45 days.

The Get Daily Forecast API is an HTTP GET request that returns detailed weather forecast such as temperature and wind by day for the next 1, 5, 10, 15, 25, or 45 days for a given coordinate location. The response includes details such as temperature, wind, precipitation, air quality, and UV index. For more information, see Request daily weather forecast data.

If you are using the Gen1 S0 pricing tier, you can request daily forecast for the next 1, 5, 10, and 15 days. If you are using Gen1 S1 or Gen2 pricing tier, you can also request daily forecast for the next 25 days, and 45 days.

Request Header

Name Required Type Description
x-ms-client-id

Security

AADToken

These are the Microsoft Entra OAuth 2.0 Flows. When paired with Azure role-based access control it can be used to control access to Azure Maps REST APIs. Azure role-based access controls are used to designate access to one or more Azure Maps resource account or sub-resources. Any user, group, or service principal can be granted access via a built-in role or a custom role composed of one or more permissions to Azure Maps REST APIs.

To implement scenarios, we recommend viewing authentication concepts. In summary, this security definition provides a solution for modeling application(s) via objects capable of access control on specific APIs and scopes.

Notes

  • This security definition requires the use of the x-ms-client-id header to indicate which Azure Maps resource the application is requesting access to. This can be acquired from the Maps management API.

The Authorization URL is specific to the Azure public cloud instance. Sovereign clouds have unique Authorization URLs and Microsoft Entra ID configurations. * The Azure role-based access control is configured from the Azure management plane via Azure portal, PowerShell, CLI, Azure SDKs, or REST APIs. * Usage of the Azure Maps Web SDK allows for configuration based setup of an application for multiple use cases.

Type: oauth2
Flow: implicit
Authorization URL: https://login.microsoftonline.com/common/oauth2/authorize

Name Description
https://atlas.microsoft.com/.default https://atlas.microsoft.com/.default

subscription-key

This is a shared key that is provisioned when you Create an Azure Maps account in the Azure portal or using PowerShell, CLI, Azure SDKs, or REST API.

With this key, any application can access all REST API. In other words, this key can be used as a master key in the account that they are issued in.

For publicly exposed applications, our recommendation is to use the confidential client applications approach to access Azure Maps REST APIs so your key can be securely stored.

Type: apiKey
In: query

SAS Token

This is a shared access signature token is created from the List SAS operation on the Azure Maps resource through the Azure management plane via Azure portal, PowerShell, CLI, Azure SDKs, or REST APIs.

With this token, any application is authorized to access with Azure role-based access controls and fine-grain control to the expiration, rate, and region(s) of use for the particular token. In other words, the SAS Token can be used to allow applications to control access in a more secured way than the shared key.

For publicly exposed applications, our recommendation is to configure a specific list of allowed origins on the Map account resource to limit rendering abuse and regularly renew the SAS Token.

AirAndPollen

The AirAndPollen object provides comprehensive environmental data. It identifies various pollen types such as tree, grass, ragweed, and mold, and pollutants including PM2.5, PM10, O3, NO2, SO2, and CO. Additionally, it reports the UV Index on a scale from 1 to 10, offers qualitative descriptions of air quality or pollen levels, and provides numerical measurements of the concentration of pollutants or pollen in the air. This detailed information helps users assess air quality and pollen conditions along their travel route.

Name Type Description
category

string

Provides a one-word qualitative description of the air quality or pollen level for the forecast period in the specified language.

integer (int32)

Provides a numerical representation of the air quality or pollen level. This value corresponds to the qualitative category property, offering a precise way to quantify the air quality or pollen level. These values range from 1 to 6, with 1 implying good conditions and 6 implying hazardous conditions.

name

string

For pollen: Returns the name of the pollen, such as tree, grass, ragweed, or mold.

For pollutants: When the name property is AirQuality, the name of the pollutant is returned in the type property. Valid pollutants include: PM2.5, PM10, O3, NO2, SO2, and CO.

For UV Index: When the name property is UVIndex, the UV index is returned in the value property. Valid UV Index values range from 0 to 11+ and represent the intensity of ultraviolet radiation. UV Index values are categorized as follows:

  • 0-2: Low
  • 3-5: Moderate
  • 6-7: High

value

integer (int32)

Provides a numerical measurement of the concentration of pollutants or pollen in the air. This value is typically expressed in units relevant to the type of pollutant or pollen being measured, such as micrograms per cubic meter (µg/m³) for particulate matter or parts per billion (ppb) for gases like ozone. Both air quality and UV are indices, so they are unitless.
