Pricing overview
Tomorrow.io offers a tiered pricing structure for its weather and climate APIs, designed to accommodate various user needs from individual developers to large enterprises. The model begins with a free developer plan, followed by several paid subscription tiers that scale with API call volume, data granularity, and feature access. Custom enterprise solutions are available for organizations with specialized requirements.
The core of Tomorrow.io's pricing revolves around access to its Weather API, offering current conditions, forecasts, and historical data, as well as the Climate API for long-term climate risk assessment. While the general structure is subscription-based, higher usage beyond plan limits typically incurs additional costs, which are detailed on the Tomorrow.io weather API pricing page.
Plans and tiers
Tomorrow.io provides predefined plans for API access, catering to different levels of usage and professional requirements. Each plan offers a set number of API calls, access to specific data layers, and varying levels of support. The plans are structured to allow users to upgrade as their needs expand.
| Plan | Price | Key Limits & Features | Best For |
|---|---|---|---|
| Developer Plan | Free | 500 API calls/day, basic data layers | Testing, small personal projects, initial integration |
| Startup Plan | $49/month | 5,000 API calls/day, additional data layers, 5-minute data resolution | Small businesses, startups, applications with moderate weather data needs |
| Growth Plan | $199/month | 25,000 API calls/day, all API layers (except premium), 1-minute data resolution, advanced support | Growing businesses, applications requiring higher data frequency and volume |
| Enterprise Plan | Custom pricing | Unlimited API calls, premium data layers, dedicated support, custom data formats, SLAs | Large organizations, critical operations, complex integrations, high-volume usage |
The API call limits define the maximum number of requests a user can make to the Tomorrow.io API within a 24-hour period. Data resolution refers to the temporal granularity of the weather data provided, with 1-minute resolution offering the most precise updates. For detailed information on specific feature sets included in each plan, refer to the Tomorrow.io pricing documentation.
Free tier and limits
Tomorrow.io offers a free tier, designated as the Developer Plan, which provides access to the API for personal use, testing, and initial development. This plan allows users to integrate weather data into applications without an upfront financial commitment.
- API Calls: The Developer Plan includes a limit of 500 API calls per day. This quota resets every 24 hours.
- Data Access: Users on the free tier can access basic weather data layers, which typically include current conditions, short-term forecasts, and some historical data points.
- Data Resolution: The temporal resolution for data on the Developer Plan may be less granular than paid tiers, suitable for general use cases.
- Support: Support for the free tier is generally community-based or limited to documentation resources.
This free tier is designed to enable developers to evaluate the API's capabilities and integrate it into non-commercial projects before committing to a paid subscription. For detailed terms and conditions pertaining to the free tier, users can consult the Tomorrow.io official documentation.
Real-world cost examples
Understanding the pricing structure through practical examples can help estimate potential costs:
-
Small Weather App (Startup Plan): A small business developing a mobile app that displays local weather for its users might require frequent updates. If the app serves 1,000 active users who check the weather 5 times a day, this would total 5,000 API calls daily (1,000 users * 5 calls/user). The Startup Plan, costing $49/month, provides 5,000 calls/day, making it suitable for this scenario without incurring overage charges. This plan offers a cost-effective entry point for applications with consistent, moderate usage.
-
Agricultural Monitoring (Growth Plan): An agricultural technology company that monitors weather conditions across 200 different farm locations every 15 minutes a day during peak growing season. This translates to (200 locations * 4 requests/hour * 24 hours/day) = 19,200 API calls daily. The Growth Plan, priced at $199/month, offers 25,000 API calls/day, accommodating this usage comfortably while providing higher data resolution for precise agricultural decisions. This scenario highlights the need for a higher-tier plan to support automated, frequent data retrieval.
-
Logistics & Delivery Optimization (Enterprise Plan): A large logistics firm needs real-time, hyperlocal weather data for thousands of delivery vehicles across multiple regions, requiring rapid updates and custom integration into their routing software. The sheer volume and critical nature of this data, potentially exceeding 100,000 API calls daily with specific data requirements, would necessitate an Enterprise Plan. This plan offers custom pricing, dedicated support, and tailored solutions for high-volume, mission-critical operations, going beyond the fixed limits of standard plans. For complex systems, a custom solution can be more cost-effective than managing overage fees on a fixed plan for high-volume cloud API consumption.
-
Energy Trading Platform (Enterprise Plan): An energy trading platform that uses weather forecasts to predict energy demand and supply across a national grid requires access to premium data layers, historical data for model training, and a high frequency of updates. This would likely involve millions of API calls per month and demand specific data formats for integration with specialized analytical models. Such a critical application would fall under the Enterprise Plan, where pricing is negotiated based on specific data needs, desired data resolution, and support level.
How the pricing compares
Tomorrow.io's pricing model can be evaluated against other weather API providers based on factors such as free tier generosity, cost per API call, data features, and resolution. Competitors often offer similar tiered structures, but the specifics of their free tiers and paid plans vary. For example, some providers might offer a higher volume of free calls but with less granular data or fewer features, while others may have higher starting prices but include more advanced analytics or integrations.
- OpenWeather: OpenWeather provides a free plan with 1,000,000 API calls/month (approximately 33,000 calls/day) for current weather data and a 5-day forecast, which is substantially higher than Tomorrow.io's 500 calls/day. However, OpenWeather's free tier often has limitations on forecast depth, historical data access, and data resolution compared to Tomorrow.io's paid tiers. Paid plans for OpenWeather start lower, such as their One Call API plan at $40/month for 1,000,000 calls/day, which is significantly more volume than Tomorrow.io's Startup Plan at $49/month for 5,000 calls/day. The OpenWeather pricing structure emphasizes high-volume, broad data access.
- AccuWeather: AccuWeather's developer program includes a free tier with 50 calls/day, which is more restrictive than Tomorrow.io's free tier. Their paid plans are generally tailored for commercial use and may involve higher starting costs, with a focus on their proprietary forecasting models and premium content. For instance, AccuWeather's Developer API packages often feature higher prices per call for specific data types.
- Weatherbit: Weatherbit offers a free tier with 500-1000 API calls/day, which is comparable to Tomorrow.io's Developer Plan. Their paid plans also follow a tiered structure, with prices starting from approximately $35/month for 10,000 calls/day. Weatherbit emphasizes global coverage and historical data access. The Weatherbit pricing details indicate competitive rates for similar data volumes.
When comparing pricing, developers and businesses typically consider not just the cost per call but also the quality and accuracy of the data, the range of available features (e.g., severe weather alerts, historical climate data, indices), the temporal and spatial resolution, and the level of technical support provided. Tomorrow.io's focus on hyperlocal forecasting and climate intelligence may justify its pricing for specific use cases where precision and advanced analytics are paramount, such as mission-critical operations leveraging cloud services.
