AccuWeather API

Overview

The AccuWeather API, developed by AccuWeather, Inc., offers developers a programmatic interface to integrate a wide array of weather-related data into their applications. Established in 1962, AccuWeather has a long history in meteorological services, and its API reflects this foundational expertise by providing access to both real-time observations and predictive models. The API is designed for a diverse set of applications, from displaying local weather conditions on consumer-facing websites and mobile applications to powering back-end analytics for sectors like logistics, agriculture, and real estate.

Key offerings include granular current conditions, multi-day forecasts, historical weather data stretching back several years, and critical severe weather alerts. This allows developers to build features such as dynamic weather displays, location-aware services that respond to changing conditions, and tools for climate research or operational planning. For instance, a travel application might use the API to suggest optimal travel times based on weather forecasts, or an agricultural platform could integrate historical precipitation data for crop management. The API supports various data formats, primarily JSON, and is accessed via standard HTTP requests, making it compatible with most programming environments. The AccuWeather API documentation provides detailed guides for getting started and utilizing specific endpoints.

The service offers a free Developer package, which includes 50 API calls per day, making it suitable for testing and small-scale personal projects. Paid plans are structured to accommodate higher traffic volumes, scaling based on the number of calls, which supports applications from startups to enterprises. The AccuWeather pricing structure details these tiers. The API's reliability and global coverage are central to its value proposition, as accurate and timely weather data is often critical for applications where environmental factors play a significant role. According to a Google Trends comparison for weather APIs, AccuWeather consistently shows high interest alongside other major global providers, indicating its broad recognition and usage in the developer community.

Key features

• Current Conditions API: Provides real-time weather observations for specific locations, including temperature, humidity, wind speed, precipitation, and visibility. This is essential for displaying up-to-the-minute weather information.
• Forecast API: Offers hourly, daily, and 5-day forecasts, as well as 10-day and 15-day forecasts, including details on temperature ranges, precipitation chances, and significant weather events. This feature supports planning and predictive analytics.
• Historical Weather API: Access to past weather data, invaluable for trend analysis, research, and validating models. Historical data can be retrieved for specific dates or date ranges.
• Weather Alerts API: Delivers severe weather warnings and advisories issued by national meteorological services. This is crucial for applications requiring timely notifications for user safety or operational adjustments.
• Location Search API: Allows developers to find specific locations (cities, towns, points of interest) by name or geographic coordinates, returning unique location keys required by other API endpoints.
• MinuteCast API: Provides hyper-local, minute-by-minute precipitation forecasts for the next two hours, useful for highly localized and immediate weather impacts.
• Indices API: Offers specialized indices such as the UV Index, Air Quality Index, and Pollen Index, which are relevant for health-related applications and outdoor activity planning.
• Tropical API: Provides information on tropical storms and hurricanes, including current positions, forecast tracks, and intensity predictions.

Pricing

AccuWeather offers a tiered pricing model designed to accommodate varying usage levels, from testing to enterprise-scale applications. The details below are current as of May 2026.

Common integrations

The AccuWeather API is built on standard web technologies, allowing it to integrate with virtually any platform or application that can make HTTP requests. Common integration scenarios include:

• Web Applications: Embedding real-time weather widgets, forecast displays, or location-based weather information on websites using JavaScript, React, Angular, or Vue.js.
• Mobile Applications: Incorporating localized current conditions and forecasts into iOS or Android apps, often for travel, outdoor activities, or daily planning.
• IoT Devices: Connecting smart home devices, agricultural sensors, or industrial monitoring systems to retrieve environmental data that can trigger actions or provide insights.
• Data Analytics Platforms: Feeding historical weather data into business intelligence tools for correlation with sales data, energy consumption, or supply chain optimization.
• Mapping Services: Overlaying weather conditions, radar data, or severe weather alerts onto maps provided by services like Google Maps Platform or Mapbox.
• CRM and ERP Systems: Integrating weather data to inform customer service, logistics planning, or resource management within enterprise software. Salesforce developers, for example, might integrate weather data to inform field service operations, as detailed in Salesforce's documentation on external data integrations.

Alternatives

• OpenWeatherMap: Offers a wide range of weather data, including current, forecast, and historical data, with a popular free tier and extensive community support.
• Tomorrow.io: Specializes in hyper-local, minute-by-minute weather forecasting using proprietary radar and AI, catering to specific industry needs with high-resolution data.
• Weatherbit.io: Provides global weather data, including current, forecast, and historical, alongside specialized APIs for air quality, marine, and agricultural data.
• Google Maps Platform (Weather Layer): While not a standalone weather API, Google Maps offers a weather layer that can be integrated into mapping applications for visual weather representation.
• AWS Weather Service: Amazon Web Services provides various data services, and while not a direct competitor as an API, it offers infrastructure that can host weather data solutions.

Getting started

To begin using the AccuWeather API, developers typically register on the AccuWeather Developer Portal to obtain an API key. Once registered, the first step is often to find the unique AccuWeather Location Key for the desired geographic area. This key is used across most API requests to specify the target location.

Here's a cURL example to retrieve the current conditions for a specific location (e.g., London, which might have a Location Key like 328328). Replace YOUR_API_KEY with your actual key and LOCATION_KEY with the appropriate integer for your target city:

curl -X GET \
  'http://dataservice.accuweather.com/currentconditions/v1/LOCATION_KEY?apikey=YOUR_API_KEY&details=true' \
  -H 'Accept: application/json'

This request fetches detailed current weather conditions for the specified location. The details=true parameter ensures that additional information, such as RealFeel® Temperature, wind particulars, and precipitation types, is included in the JSON response. After executing this cURL command, the API will return a JSON object containing the current weather observations, which can then be parsed and displayed in an application. For more advanced requests, such as forecasts or historical data, different endpoints would be used, as detailed in the AccuWeather API reference documentation.
