How the ClimaCell Microweather API Is Changing the Game

If you're a developer looking for a weather API, you're probably overwhelmed by the number of options out there. Some paid, some free, some new, some old — it's very hard to see the differences. One reason they all look the same is that, up until now, all of the weather APIs in the world used the same basic sources of data from the government — radar, satellites, and weather stations. This means that the main way to differentiate between them is in how they take the public data available and model and package it.

The ClimaCell Micro Weather API is different. Every traditional API maxes out at about 12,000 reliable data sensing points worldwide between radar, weather stations and satellites, while ClimaCell uses those same sensing points along with 1.5 million more and counting. It's the first API that uses all of those same sources used by other APIs, but adds millions of proprietary data sources from wireless networks and other (still in stealth mode) sensing technologies. So how does this affect the API itself? The difference is in the granularity of the data. ClimaCell can sense more weather, so it can deliver more granular real-time and forecast insights through its API. Here's a look at the differences.

ClimaCell Micro Weather API vs. other weather APIs

It's no longer acceptable to use a weather API that can only deliver updated information every 10 minutes or that can only zoom in to a 2-mile area. Nor is it ok to see a forecast out in hour increments when some critical weather changes happen in between hour intervals. Companies and apps in the new economy need more; they need street-level, minute-by-minute data. ClimaCell's Micro Weather API is the first to deliver the granular level of data needed to power drones, guide autonomous cars, and give businesses the ability to make up-to-the minute decisions based on micro weather in a specific location. Companies using the API are already seeing the difference.

Unique Functionality

In addition to delivering data not available through other weather APIs, the ClimaCell Micro Weather API has functionality that sets it apart. Here are three features not available in most other weather APIs:


ClimaCell's API has powerful alerting capabilities designed to proactively inform you of weather conditions at a given location. Each alert can be defined using multiple layered rules; for example "if it's below 32 degrees and winds gusts are over 20 mph." Alerts can be sent to different groups of people that you define and can be communicated in three ways: 1. back to your system, 2. email, or 3. SMS. You can also specify that you want the alert to be communicated at the time of the event or as far out as 6 hours. (Soon you'll be able to set alerts for days in advance).


When selecting locations to track with the ClimaCell API, you can choose a specific location based on latitude/longitude or street address. In addition, ClimaCell's API offers the unique ability to create a rectangular grid around an area, and track weather within equally sized rectangular areas inside the grid. This allows for easy analysis of multiple "zones" within a grid without having to create a separate polygon for each zone.


Some apps need more than just the raw weather data. For developers that want to build apps with a visual representation of the data, ClimaCell's API can deliver visual tiles on a weather map, showing precipitation, and soon other weather parameters as a colorful layer. This is ideal for any company that relies on a map visual as part of their business and would benefit from having the weather overlaid on the map.

Getting Started

ClimaCell has both a free version and paid versions of it's API. To find more information about the weather API, visit If you feel like you have enough information and you're ready to try the free version, or take a free trial of a paid version, please follow these steps:

  • Visit our API Options Page to choose the options best suited for you
  • After you choose the plan that works for you, you'll register here.
  • You'll then receive your Token/Key by email and can begin using the API
