How this service works
Fog and low-visibility risk at an airport from the temperature-dew point spread, wind and visibility.
Output
Returns a structured fog-risk verdict (likely/possible/unlikely or similar), the temperature in Celsius, dew point in Celsius, temperature-dew point spread, wind speed in knots, visibility in miles, a human-readable summary, a list of reasons contributing to the risk, thresholds used for the assessment, observation time, data source URL, data age in minutes, and optional disclaimer or degraded-mode flags.
Example use cases
Pre-dawn departure fog check
“Before my 6am departure from KORD, can you check the current fog risk there — I want to know if the dew point spread and winds suggest low visibility is likely this morning.”
Dispatch go/no-go visibility decision
“I'm dispatching a flight out of KBOS — what's the fog risk assessment right now? Give me the spread, wind, and a verdict on whether low-visibility conditions are likely.”
Monitoring multiple hub airports for fog
“Check the fog risk at KLAX for me — is the temperature-dew point spread tight enough to worry about, and what's the current visibility and wind situation?”
Technical details
Endpoint
GEThttps://aviation-weather.x402tookit.com/fog-risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a fog or low-visibility risk assessment derived from the temperature-dew point spread at a single airport. It is more targeted than a full METAR decode or forecast — choose it when the question is specifically about fog or IFR visibility risk, not general flight category or wind conditions. Ideal for pre-flight briefings focused on ground fog, radiation fog, or low-ceiling visibility hazards.
Side effects
- Invalid or unrecognized ICAO code returns an error or null fields
- Airport has no live METAR data — response may include degraded flag and null sensor values
- Stale observation data — ageMinutes may be high and disclaimer included
- Network timeout or upstream weather data source unavailable
- Missing required icao query parameter returns a validation error
