5 Things to Look for in a Weather API
and 5 Things to Avoid
With so many options on the market, how do you know which Weather API is right for you? The answer is, “it depends.” Pricing, ease of access, latency, and amount of data are all things to consider, but most important is your application. How will you be using the information, and what features are most important to you?
We’ve highlighted some tips to consider when selecting a solution, and some things to avoid.
What to Look for When Selecting a Weather API
1. Access to Real-Time, In-Situ Data – Many APIs rely heavily on model-based or gridded data. Sometimes that’s good enough, but when it comes to protecting lives and property, you need data at specific locations. High-resolution, local data captures nuances that gridded data may smooth out or miss.
Accuracy and ground-truth are not things to overlook, especially during extreme weather conditions. In-situ observations are also available in real-time, with no delays for processing or modeling. This is crucial for time-sensitive applications, such as emergency response or forecast warnings. When timely decisions and localization matter, choose a solution with real-time data.
Things to Avoid
1. Over-Reliance on Modeled Data – Some providers prioritize gridded models over real-world observations, which can introduce errors or be less accurate. If accuracy matters, choose an API that emphasizes observed station data.
2. Hidden Data Gaps – Not all APIs disclose where their data comes from. Some lack coverage in critical regions, leading to unreliable insights. Look for a vendor that offers transparent metadata so users know exactly where their data originates.
3. Slow or Inconsistent Updates – Delays in weather data can make it unusable for fast-paced decision-making. Avoid APIs that refresh infrequently or lag. Real-time updates are critical when timing matters.
4. Lack of Quality Control– Some APIs provide raw data without any filtering, leaving users to sort through inaccuracies or manually quality control the data themselves, which takes time away from decision-making and monitoring the current situation. Choose a vendor with quality-controlled data to ensure dependable information.
5. No Customer Support – While a certain price point may be attractive, be aware that a low-cost provider may lack support. This can result in not getting notified about network outages or taking days to respond to requests when a timely answer is needed. Make sure you have a clear understanding about what to expect for support responses from your API vendor.
2. Comprehensive Data Coverage – A great API should aggregate data from multiple sources, including government networks, private networks, and research institutions. There are free and inexpensive data sources that all APIs pull from, but an API that prioritizes diverse datasets and works directly with data providers to share data will ensure you have the most accurate, complete information available.
3. Quality-Controlled Data – Raw weather data can contain errors, which is no surprise to those who view/use weather data. This makes quality control essential. Always research or speak with the API vendor about their quality control processes. What kind of quality checks are they doing? It’s not always the number of checks that’s important, it’s about their approach, their data integrity, transparency, and the amount of historical data they can reference. You want access to clean data, without the hassle of cleaning it yourself, and you want to ensure it’s accurate.
4. Low Latency & High Reliability – How quickly data is available and getting it reliably makes a huge difference if you’re responsible for lives and property. Minutes matter for time-sensitive applications, such as evacuations, sending out restoration crews, or air quality updates. Conditions can change quickly, and delayed data can increase the risk of dangerous situations. If your application requires having the most up-to-date data, you’ll want to look for an API with minimal latency and guaranteed uptime.
5. Scalability & Flexibility – A top-tier API should work for everything from individual developers to larger teams. The API should be flexible where you can tailor data retrieval to your specific needs. This includes being able to request only the variables or stations you need, work seamlessly with various applications and in easy to use formats (JSON, CSV, etc.), and evolve without disrupting developers integrating the data.
When researching APIs, consider the features above, but also spend time to demo your top choices and see which one is the best fit for your application. All Weather APIs are not created equal! Read on to learn five things to avoid when selecting your API.
