How is the Strongest Crosswind calculated for airports?

Crosswind values are mathematically calculated using vector decomposition of current wind speed and direction relative to the active runway's magnetic heading.

How many airports are listed in the adverse weather rankings?

Each of the four categories contains a total of 25 ranked airports worldwide. By default, the top 10 are displayed, and clicking the 'Show all' button reveals the full top 25 list.

What layers are included in the interactive airport weather map?

The map displays airports worldwide with flight categories (VFR, MVFR, IFR, LIFR), live satellite weather info, a 24-hour satellite forecast, and Flight Information Region (FIR) boundaries.

Adverse Weather Airports & Statistics Guide

The Adverse Weather Conditions page on Atmolix provides live specialized statistical data for airports worldwide that are currently impacted by adverse meteorological conditions.

Global Record Highlights

At the top of the page, two critical real-time aviation metrics are prominently highlighted:

Airport with the Strongest Wind in the World: Displays the airport currently reporting the highest sustained wind speed and gusts globally.
Airport with the Strongest Crosswind in the World: Highlights the location experiencing the highest crosswind component relative to the active runway.

Ranking Categories

The page features 4 ranking categories. Each category contains a total of 25 ranked airports. To ensure optimal page layout, the top 10 airports are shown by default, and clicking the Show all button expands the list to display all 25.

Strongest Winds: Ranks airports reporting the highest overall wind speeds and peak gusts according to the latest METAR observation.
Strongest Crosswind: Ranks airports experiencing the highest crosswind components. Key Note: Crosswind values are not pulled directly as raw observation values; instead, they are automatically calculated by vectorially decomposing current wind direction and speed against the magnetic heading of the active runway (RWY).
Poor Weather: A composite category featuring airports affected by severe weather conditions, such as thunderstorms, heavy precipitation, low cloud bases, and atmospheric instability.
Low Visibility: A targeted ranking focusing on airports reporting the lowest horizontal and vertical visibility (heavy fog, dense snowfall, blowing dust).

The crosswind component calculation uses the trigonometric formula: Crosswind = Wind Speed × sin(Wind Angle - Runway Heading). This delivers an accurate assessment for pilot situational awareness and landing safety.

Interactive Airport Map & Weather Layers

At the bottom of the page, a full interactive map displays airports worldwide, enriched with essential aviation layers:

Flight Categories: Color-coded status indicators for every airport based on flight rules – VFR (Green), MVFR (Blue), IFR (Red), and LIFR (Magenta).
Satellite Weather Info: Real-time satellite overlays highlighting cloud cover, precipitation cells, and frontal systems.
24-Hour Satellite Forecast: An animated 24-hour forecast tracking air mass movements and severe weather progression for the day ahead.
FIR (Flight Information Regions): Official boundaries of Flight Information Regions, allowing pilots and flight planners to identify affected airspace control sectors.
