2025: Leaps instead of increments

A year of deeper data and experience overhaul, 2025 was one of the most important years in the history of Ventusky.

Throughout the year, the platform expanded both in depth and precision—adding new global models, higher-resolution data, faster updates, and tools aimed not just at enthusiasts, but also at professionals.

Below is a clear overview of what changed and why we're excited about it:

Higher Resolution, More Models, Better Accuracy

Forecast accuracy took a major step forward in 2025 thanks to the addition of several advanced numerical weather models:

• ECMWF high-resolution model with hourly forecast steps, offering one of the most trusted global forecasts in unprecedented detail.
• ICON-CH, improving alpine and mountainous forecasts, especially in complex terrain.
• HARMONIE, bringing higher-precision short-range forecasts to parts of Europe.
• NAM high-resolution model, expanding detailed forecasting across North America.

Together, these models allow users to compare forecasts, understand uncertainty, and choose the most relevant data for their location.

Radar, Rain, and Faster Updates

Precipitation data and radar coverage received major upgrades in 2025:

• Radar refresh rate improved to 5-minute intervals, allowing faster and more precise storm tracking.
• A major expansion in worldwide rainfall coverage, providing more complete precipitation data across the globe.
• AI-based hail probability forecasts, helping users anticipate severe convective storms earlier.

These improvements strengthened Ventusky as both a planning tool and a real-time weather companion.

Ultra-High Resolution Satellite Imagery

Ventusky introduced high-resolution satellite imagery from Meteosat Third Generation (MTG).

This brought sharper cloud detail, faster updates, and better insight into storm development across Europe and Africa, especially during rapidly evolving weather situations.

New Layers for Advanced Analysis

Several additions in 2025 were aimed at users who want to understand the atmosphere in greater depth:

• Geopotential height layers at 850, 500, and 300 hPa.
• Isobars and professional synoptic maps.
• Improved weather graphs with clearer trends and additional data insights.

These tools make Ventusky more useful for advanced users while remaining accessible.

Maps Built for the Real World

Ventusky expanded its map foundation beyond meteorology:

• New hiking maps optimized for outdoor activities.
• Street maps for easier orientation in cities and during travel.
• Expanded camera coverage, offering visual confirmation of real-world conditions.

These updates help bridge the gap between weather data and real-life decision-making.

Weather and Health

In 2025, Ventusky also added features focused on everyday health:

• UV Index layer, helping users assess sun exposure risks anywhere in the world.

A small addition with practical impact, especially during summer months.

Version 50: A Cleaner, Smarter Interface

All these features culminated in Ventusky Version 50, a major redesign of the app interface.

• Cleaner layout and improved navigation.
• Better organization of layers and data.
• A modern design built to scale with growing complexity.

The new interface makes powerful data easier to explore without sacrificing clarity.

Looking Ahead

2025 was about building stronger foundations and pushing Ventusky forward in meaningful ways.

As we move into the new year, our goal remains the same: to keep making complex weather data clearer, more accurate, and easier to use - whether you rely on Ventusky out of curiosity, passion, or necessity.

We’re excited to continue improving the platform in 2026 and to explore new ways of helping you better understand what’s happening in the atmosphere around you.
