Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Ivo Lukacovic launches Windyty as a personal amateur project built on Cameron Beccario's open-source earth project, focusing solely on wind visualization using GFS data. There is no business model, no team, no monetization, and no users beyond early adopters. The product is a single-purpose tool driven entirely by its creator's personal passion for kiting and flying.
Windyty rebrands to Windy, launches iOS and Android apps, expands from wind-only to 50+ weather layers, and grows to 300,000 daily users by mid-2018. The team grows to six employees and opens its first sales position. An API and community forum are launched, building developer and user ecosystems. The product remains entirely free with no subscription tier.
Windy introduces Premium subscriptions at $19.99/year with a 7-day auto-renewing free trial, its first monetization beyond the Windy API. Lukacovic leaves the Seznam.cz board to focus full-time on Windy. The Copernicus CAMS air quality partnership and webcams.travel integration significantly expand the platform. Bloomberg profiles Windy as a mainstream favorite. The free tier remains ad-free and high-quality, but the auto-renewing trial introduces the first dark pattern concerns.
Windy moves previously free features behind the Premium paywall in late 2022, including satellite archives, extended comparison forecasts, and higher resolution maps. Free favorites are capped at 3. Revenue reaches CZK 217 million in 2023 with profit doubling to CZK 60 million. Version 39's major UI redesign in July 2023 draws significant user backlash. Despite the friction, the product continues improving with a redesigned Hurricane Tracker, Waves & Tides features, and the core free tier remains fully functional and ad-free.
Windy acquires meteoblue to expand B2B capabilities, integrates AIFS AI forecasting for 15-day predictions, and launches the Radar+ combined layer. Premium pricing increases 35% in December 2024 and another 24% regionally in mid-2025, the first price changes since launch. The app reaches 59 million downloads. Despite pricing increases and the paywall tightening from 2023, the product remains healthy: the free tier is ad-free, high-quality, and continuously improved, scoring just 10/100 on the enshittification scale.

Windy discontinues API v2.3 and transitions to the v4 API built on the Leaflet mapping library. The new API allows developers to embed animated weather maps on websites using the open-source Leaflet ecosystem. A free tier is available for non-commercial use, with a paid version at 720 USD/year for commercial applications.
Lukacovic Leaves Seznam.cz Board to Focus on Windy
Ivo Lukacovic steps down from the board of directors of Seznam.cz, the Czech Republic's largest internet portal, to dedicate himself fully to Windy.com and his other technology projects. He remains sole owner of Seznam.cz. The move signals Windy's transition from a side project to his primary professional focus.
Copernicus CAMS Air Quality Partnership Signed
Windy signs a partnership with the Copernicus Atmosphere Monitoring Service (CAMS), operated by ECMWF on behalf of the EU, to integrate air quality forecasts. The partnership adds nitrogen dioxide, fine particulate matter, and Aerosol Optical Depth layers to Windy, making it one of the first weather apps to offer consistent air quality and wind forecasts in animated format.
Windy Plugin System Launched for Third-Party Developers

Plugins run inside the Windy.com environment, are developed in JavaScript, and published as npm packages. Examples include sounding displays for paraglider pilots and sun/moon position tools for photographers.
Webcams.travel and Lookr.com Merged into Windy
Windy integrates webcams.travel (founded 2007 by Jorg Eugster) and lookr.com into the Windy platform, redirecting both sites to windy.com/webcams. The merger brings a global network of community-contributed webcams providing real-time visual weather confirmation. Windy commits to continuing the free webcam API for developers.
Bloomberg Profiles Windy as Favorite Weather Site for Climate-Obsessed
Bloomberg Businessweek publishes a feature article about Windy.com, describing it as the new favorite website for people interested in detailed weather and climate data. The article profiles founder Ivo Lukacovic and his obsessive approach to weather visualization, bringing significant mainstream attention to the platform.
Windy Premium Subscription Launched at $19.99/Year
Windy introduces its first paid tier, Windy Premium, at $19.99/year with a 7-day free trial. Premium features include 1-hour forecast steps, extended 10-day forecasts, 4 model updates per day (vs 2 for free), and higher resolution maps. The free tier remains fully functional and ad-free. The launch is described as costing 'just the price of a lunch.'
Major Sea Currents and Tidal Currents Update Released
Windy version 28.1.1 significantly improves sea current maps and adds tidal currents as a new data layer, using Copernicus Marine Service (CMEMS) data. The update provides satellite-derived tidal current data at 0.25-degree resolution, expanding Windy's marine forecasting capabilities for sailors and boaters.
Previously Free Features Moved Behind Premium Paywall
Windy restructures its free and premium tiers, moving several previously free features behind the paywall: satellite archive (12 months), compare forecast extended to 10 days, and higher resolution for ECMWF, NAM, and AROME maps. Free users also see favorites limited to 3 (from unlimited). Community backlash is significant, with users calling it a negative-value paywall strategy rather than genuine premium additions.
Hurricane Tracker Redesigned with Multi-Agency Forecasts
Windy releases a redesigned Hurricane Tracker featuring storm movement cones from multiple national meteorological agencies, satellite archive compatibility, and forecast track lines with waypoint details including wind speed, pressure, and timing. The tracker works with any Windy layer and forecast model, and automatically displays the storm closest to the user's location.
Version 39 Major UI Redesign Draws Polarized User Response
Windy version 39 introduces a sweeping redesign of the app interface including a reworked picker system, new layer pinning, and relocated navigation elements. Community reaction is sharply divided: some users call it '15 steps back' and 'very mid-grade,' while professional meteorologists report lost functionality like scrubbing through Skewt forecast profiles. iPad users lose their browser-like interface in favor of the phone layout.
Waves and Tides Feature Added with Global Coverage
Windy adds tidal forecasts across the globe using data from WorldTides.info, integrated into a Waves & Tides table in the detailed forecast view. The feature provides tide height predictions at official tide stations and adds wave energy as both a new layer and forecast detail, expanding utility for marine users.
Webcams Map Feature Launched with Live Preview
Windy introduces a Webcams Map feature that displays live thumbnail previews of all webcams directly on the interactive map. Users can toggle the preview layer on and off to see actual weather conditions at locations worldwide. The feature is free for all users, consistent with Windy's commitment to developing both premium and free features.
Version 42 Launches with New Plugin System
Windy version 42 introduces a completely rebuilt plugin system, allowing developers to extend Windy.com by building JavaScript plugins served from the windy-plugins.com domain. The update includes a plugin template, developer documentation, and deployment via GitHub Actions. The revamped system replaces the older internal plugin architecture.
Windyty Acquires Majority Stake in Meteoblue
Windyty SE acquires a majority stake in meteoblue AG, a Basel-based weather forecasting company spun off from the University of Basel in 2006. Meteoblue specializes in high-precision B2B and B2G weather services with customers in 60+ countries. The acquisition complements Windy's B2C strength with meteoblue's business and government market presence. Financial terms are not disclosed.
New Windyty Prague Office Showcased with Nature-Inspired Design
Office Snapshots profiles Windyty's Prague headquarters, designed by UNLIMIT DB with sea, kiting, and wind-inspired elements including cloud-shaped acoustic ceiling panels and kiting-themed meeting room wallpaper. The modern workspace reflects the company's growth from a one-person project to a mid-size team with dedicated office space.
AIFS-Powered 15-Day Premium Forecast Launched
Windy integrates ECMWF's Artificial Intelligence Integrated Forecasting System (AIFS) to extend the ECMWF forecast from 10 to 15 days. AIFS runs at 28km resolution and uses approximately 1,000 times less energy than traditional forecasting methods. The extended forecast is Premium-only, providing temperature trends, precipitation probabilities, and wind speed predictions beyond the standard 10-day window.
Radar+ Layer Launched Combining Satellite and Radar Imagery
Windy introduces Radar+, a combined layer merging satellite and weather radar data into a single visualization. The feature includes Hurricane Tracker compatibility and a 365-day historical archive for Premium users. Radar coverage is expanded to Croatia, Turkey, the Bahamas, Cayman Islands, Tonga, and other regions during 2024.
Meteosat Third Generation Satellite Imagery Integrated
Windy integrates imagery from the Meteosat Third Generation (MTG) satellite, providing significantly higher resolution views of weather patterns. The new satellite data enhances the Satellite layer across the platform, offering more detailed cloud, precipitation, and atmospheric observations for European and African coverage areas.
First-Ever Premium Price Increase: $25.99 to $34.99 (35%)
Windy raises its Premium annual subscription price from $25.99 to $34.99, a 35% increase and the first price change since Premium launched in March 2020. The company attributes the increase to rising data costs after years of absorbing inflation. Community reaction is mixed: some users accept the rationale while others criticize the steep jump after years of stable pricing.
Second Regional Premium Price Increase of 24.3%
Windy implements a second regional price increase, raising the UK annual subscription from 18.49 GBP to 22.99 GBP (24.3%) and the US annual subscription from $18.99 to $24.99 (31.6%). The increase comes just seven months after the December 2024 hike, accelerating the pricing trajectory after four years of stable rates.
