How to read a METAR

A METAR is the routine weather report every airfield issues, every half hour or hour. It reads left to right as a series of groups, each with a fixed format. This is the station's own report as of the newest line in the log. The home page moves it on every half hour after that.

GroupWhat it meansAt this station
METAR Routine weather report, issued on a regular schedule. Routine, at 20 and 50 past every hour, as at many real airports. Each report is worked out from the observation log for its own half hour.
XSTR Station identifier, the four-letter ICAO location code. Storm Tracker itself. Each project has its own code, listed in the station directory on Station info.
140208Z Observed on day 14 of the month at 02:08 UTC. The newest line in the log, then every half hour after it. Between lines the weather only settles, so the page knows it ahead of time.
24016KT Wind from 240° (southwest) at 16 knots. Storm energy. Every line in the log adds the energy of its status's wind, and the energy halves every 4 hours. 16 knots is the one wind that carries all of it.
8000 Visibility 8,000 m. The sky that goes with the wind: clear below 6 knots, then partly cloudy, drizzle from 14, thunderstorms from 22, a tropical storm from 34, and a hurricane from 64, the real thresholds for both.
-DZ Light drizzle.
BKN020 Broken clouds (5 to 7 eighths) at 2,000 ft.
09/24 Temperature 9 °C, dew point 24 °C. 9 active systems and 24 cleared or dissipated.
Q1026 Pressure 1,026 hPa, reduced to sea level (QNH). 1022 hPa when the log is calm, deeper as the wind rises, the way a real storm deepens, and up to 8 hPa higher for a day or so after a system clears.
BECMG Becoming: a lasting change is expected within two hours. The groups after it describe the change. The forecast for the next two hours. Between lines the storm energy only fades, so unless something new is logged, this comes true.
9999 Visibility 10 km or more.
NSW No significant weather: the weather reported before it ends.
SCT040 Scattered clouds (3 to 4 eighths) at 4,000 ft.
RMK Remarks follow, in contractions and plain language.
STMP XSTR 012033Z SECRET Not part of any real report: a Stormy Fans stamp code. STMP, then the station, the day and time the code was made in UTC, and a word. A stamp for Stormy Fans members, who enter the whole group at stormyfans.com/code/.

Each system's METAR follows the same pattern. Its temperature and dew point are a fixed pair chosen for the project, and its wind, cloud, and weather come from its status. Pilots are taught to read a report more than once, and the coded lines on this site reward the habit.

Other coded lines on this site

SPECI
A special report, issued between routine ones when conditions change sharply. Systems in a thunderstorm, wind shift, or tornado report this way.
TAF
Terminal aerodrome forecast. The station's outlook for the next day or two sits at the end of the forecast discussion, with BECMG for lasting changes and TEMPO for passing ones.
FXST01 XSTR · AFDSTR
The header at the top of every page, as on a product from a real forecast office. FX marks a miscellaneous forecast, ST the area, and 01 the sequence. The six digits after the station are the issue time as day, hour, and minute in UTC. AFDSTR names the product: an area forecast discussion from STR.
/////
Missing data. A private station reports its status but withholds everything else, so each group of its METAR is replaced with slashes of the same length.
UA /OV /TM /TP
A pilot report, which heads each visitor comment. UA marks a routine report, /OV the location, /TM the time in UTC, and /TP the aircraft type, which here is always FAN.
STMP
A Stormy Fans stamp code, at the end of the remarks in some reports: STMP, the station, the day and time the code was made in UTC, and a word. It is not part of any real report. Members of Stormy Fans enter the whole group at stormyfans.com/code/ for that station's stamp.
&& and $$
Section and product endings in a forecast discussion. The station signs off with $$ FORECASTER...STORMY.

Station directory

Every identifier begins with X. ICAO assigns no location codes beginning with X, so none of these can be mistaken for a real airfield. J is unassigned as well, with one exception.
