Duties and responsibilities

  • Perform routine surface weather observations every hour and issue special observations when conditions change significantly
  • Observe and record temperature, dew point, wind speed and direction, atmospheric pressure, visibility, sky condition, and present weather
  • Encode observations in METAR format for aviation weather products and SYNOP format for international meteorological data exchange
  • Operate and monitor the Automated Surface Observing System (ASOS) and supplement automated observations with manual assessments
  • Issue pilot weather reports (PIREPs), wind shear alerts, and other special aviation weather advisories as conditions warrant
  • Maintain accurate station logs, equipment calibration records, and data quality documentation
  • Transmit observations to NWS, FAA, and other authorized users within required timing windows
  • Identify and report equipment malfunctions or sensor anomalies that may affect observation quality
  • Coordinate with air traffic control, pilots, and dispatchers to provide current field weather conditions on request
  • Conduct climatological data collection—precipitation measurements, evaporation pan readings, and soil temperature when assigned

Overview

A Weather Observer is the person responsible for the official weather record at an observing station—the certified, transmitted measurement that pilots depend on for approach minimums decisions and that meteorologists rely on to anchor their forecasts. When the METAR shows 1-mile visibility with fog at an airport at 6 AM, those numbers came from a Weather Observer who looked out at the field, assessed conditions against established criteria, and encoded and transmitted the observation within the required time window.

The core work is disciplined measurement applied consistently. Temperature and barometric pressure come from instruments; visibility and sky condition come from trained human assessment combined with ASOS sensor data. An experienced observer develops calibrated judgment for estimating visibility—knowing what 3/4 of a mile looks like through different types of precipitation, fog, haze, and dust—and for accurately classifying sky condition coverage and cloud heights across multiple layers.

Special observations are where the Weather Observer's judgment matters most. ASOS systems are programmed to detect broad threshold crossings, but the human observer is the authority when conditions are complex, rapidly changing, or at the edge of the automated system's detection capability. A pilot deciding whether to attempt an instrument approach in marginal conditions is partly making that decision based on the Weather Observer's most recent SPECI. That responsibility is real and demands serious attention to accuracy.

Airport-based observers work in direct coordination with air traffic control, pilots on frequency, and dispatchers calling for field conditions. The ability to communicate weather information clearly, accurately, and without delay is a practical skill that the job requires in addition to the observation competency itself.

For candidates who value precision work, a low-drama professional environment, and the satisfaction of producing data that demonstrably matters for safety, Weather Observer is a role with genuine appeal.

Qualifications

Certifications:

  • FAA Certificated Weather Observer (CWO) certificate (required for official observation stations; some employers train and sponsor candidates)
  • Current CPR certification (required at some facilities)

Education:

  • High school diploma or equivalent (minimum for entry-level positions)
  • Associate or bachelor's degree in meteorology, atmospheric science, or physical science strengthens candidacy for federal NWS positions
  • Military weather training (Air Force 1W0X1, Navy AG, or equivalent) is a recognized pathway

Federal position requirements:

  • U.S. citizenship for NWS and FAA positions
  • Background investigation
  • Drug screening
  • 15+ semester hours of physical science for federal Weather Technician/Observer classifications

Technical skills:

  • METAR and SYNOP encoding from memory — accuracy and speed matter in an ATC environment
  • ASOS operation: sensor monitoring, maintenance alerts, augmentation procedures
  • Visibility estimation technique: knowing reference objects and calibrated distance assessment
  • Sky condition observation: estimating cloud coverage (oktas or tenths), layer heights, and cloud types
  • Station equipment: thermometers, barometers, ceilometers, present weather detectors, anemometers

Physical and scheduling requirements:

  • Shift work: nights, weekends, holidays; 24/7 coverage at active observation stations
  • Ability to work in a small, often isolated facility
  • Visual acuity sufficient for visibility and sky condition observation

Career outlook

Weather Observer positions exist primarily in two employment contexts: NWS-affiliated federal positions (GS-classified, strong benefits, slower hiring process) and contractor positions at FAA weather service stations (faster to access, lower pay, fewer advancement paths). Both segments are relatively stable but not growing—automation has absorbed the routine observation functions at many smaller airports, and budget pressure on federal agencies limits new position creation.

The remaining human observer positions are concentrated at airports with significant commercial traffic and at specialized NWS facilities where the complexity of weather or the criticality of aviation operations requires human judgment alongside ASOS automation. These positions are not going away in the near term—the FAA's own regulations require human certification and observation at certain airports—but they are not expanding meaningfully either.

Military weather observer training remains one of the best pipelines into the civilian field. Veterans with Air Force 1W0 or comparable ratings leave service with training that directly satisfies federal hiring requirements, and veterans' preference in federal hiring gives them an additional advantage in NWS and FAA position competitions.

For workers who want to advance beyond the observer level, the path runs toward Weather Technician (which requires more education and training) and Meteorologist (which requires a bachelor's degree with heavy meteorology coursework or the equivalent). Some observers pursue the NWS's internal development programs while working, completing coursework that qualifies them for higher GS classifications.

Private sector weather companies (commercial airlines' meteorology departments, energy company weather risk units, private forecasting firms) hire from the same pool of trained observers and technicians, typically paying less than federal positions but offering more varied work and faster hiring timelines.

Sample cover letter

Dear Hiring Manager,

I'm applying for the Weather Observer position at [Station/Facility]. I hold a current FAA Certificated Weather Observer certificate and I have 18 months of observation experience at [Station], where I provide supplemental observations to the ASOS unit and maintain the station log.

My current station is a contract position at a general aviation airport with moderate traffic. I issue hourly METARs and SPECIs when conditions change, coordinate with the FBO and occasional itinerant pilots for current field conditions, and maintain the instrument calibration log. I've not had a reportable accuracy deviation in 18 months.

The aspect of the work I've taken most seriously is visibility estimation. Early in the position I realized that my distance calibration on marginal visibility days wasn't as precise as it needed to be for the threshold values that matter to pilots—the half-mile, three-quarter-mile, and one-mile thresholds where approach minimums decisions turn. I spent time systematically calibrating against known reference objects at different times of day and in different precipitation types, and I now have genuine confidence in my assessments in the conditions that matter most.

I'm applying to [Station] because the traffic volume is higher and the observation environment is more operationally demanding than my current station. I want to work in an environment where the observations I produce are being used in real time by ATC and commercial aviation, not just logged for the record.

I'm available for shift work and can begin within 30 days of an offer.

Frequently asked questions

What FAA certification is required for official weather observers?
The FAA Certificated Weather Observer (CWO) certificate is required for anyone who takes official weather observations at FAA-certified weather observing stations. The certification requires passing written and practical examinations that test knowledge of observation methodology, METAR encoding, equipment operation, and regulatory requirements. Some employers (particularly NWS contractors) provide training and sponsor candidates through the certification process.
What does a METAR include and why is it important?
A METAR (Meteorological Aerodrome Report) is the standardized aviation weather observation format used worldwide. It includes station identifier, observation time, wind direction and speed, visibility, current weather phenomena, sky condition (cloud layers and heights), temperature and dew point, and altimeter setting. Pilots use METARs to determine whether an airport is above minimums for instrument approaches, and ATC uses them for traffic management. An inaccurate METAR can directly affect flight safety decisions.
Are Weather Observers at airports considered government employees?
Not always. Many FAA weather observation stations at airports are staffed by contract employees working for Lockheed Martin or other government contractors rather than directly by federal agencies. These positions provide similar duties to federal NWS observer positions but typically have different pay scales, benefits structures, and advancement opportunities. NWS positions are federal GS-classified roles; contractor positions are private sector employment.
What is a special observation and when is one issued?
A special observation (SPECI) is issued between regular hourly METARs when conditions change significantly enough to affect aviation safety—when visibility drops or rises through a reporting threshold, when ceiling height crosses a minimums category, when a thunderstorm moves on or off the field, when wind shifts significantly, or when precipitation type changes. Weather Observers monitor conditions continuously and issue SPECIs without waiting for the scheduled hourly observation time.
How much does automation affect Weather Observer employment?
ASOS has automated routine hourly observations at most certificated airports, reducing but not eliminating the need for human observers. Certificated Weather Observers remain required at many airports to supplement ASOS with observations that the automated system cannot accurately measure—precipitation type identification (the distinction between freezing rain and ice pellets, for example), certain visibility conditions, and tornado or waterspout sightings. The role has shifted from primary observation to ASOS oversight and supplemental observation.
