What a METAR report includes and why flight delays aren’t part of it

METAR Magic: What’s in a Standard Weather Snapshot and what isn’t

If you’ve ever flown or planned a trip that touches the sky, you know weather isn’t just background noise. It’s a real-time navigator, a safety check, and yes, a bit of theater up there. In the Limited Aviation Weather Reporting System world, METARs are the daily, fly-it-now kind of data. They give pilots and air traffic controllers a quick, precise picture of current conditions at a specific airport. But there’s a common question that comes up, especially for learners: what exactly is included in a METAR, and what’s not?

Let me explain it in plain terms. A METAR is a weather observation report. Think of it as a weather photo of the airfield at a particular moment. It’s concise, coded, and designed to be read fast—so you don’t have to fumble through a long paragraph to know if you can take off safely. With that in mind, here’s what you’ll typically find in a standard METAR.

What’s in a METAR (the essential menu)

• Wind direction and speed

This isn’t a guess. The report tells you the wind’s origin direction and how fast it’s blowing, sometimes with gusts. It’s practical because wind affects takeoff and landing performance, runway choice, and even how you handle a crosswind on rollout.

• Visibility

This is the clearest signal of how far you can see, usually expressed in statute miles (or meters in some regions). Reduced visibility can change decisions about takeoff clearance, approach minimums, and whether to divert.

• Cloud cover and weather phenomena

METARs describe cloud layers with exact coverage (scattered, broken, overcast) and often give a height for the base of the lowest significant layer. They also include weather phenomena like rain, snow, fog, drizzle, or thunderstorms. In short, this is the weather story—what you’ll actually be seeing if you look upward.

• Temperature, dew point, and altimeter

You’ll see the air temperature and dew point, which help pilots gauge humidity and potential icing conditions. The altimeter setting (how high the atmosphere reads on your pressure instrument) is included too, so you can set your cabin pressure and altimeter correctly for safe flight.

• A few extras that matter

Some METARs also carry indicators for rain, freezing rain, or ice pellets; sometimes there are remarks about recent weather that might affect the immediate past conditions. All of these bits help with quick risk assessment and flight planning.

If you’re familiar with aviation weather interfaces, you’ll notice METARs are designed to be fast to read, even when the weather changes by the minute. They’re a snapshot, not a diary. The collection of data points is tuned for what pilots and controllers need in real time.

What METAR does not include (the part that trips people up)

• Flight delays

Here’s the key distinction: METARs contain weather observations, not scheduling information. They don’t tell you how late a flight is, what the gate situation looks like, or how many planes are queuing up on the tarmac. If you’re after delays, you’re looking at a different data stream—airline operations systems, airport status boards, NOTAMs, or flight-tracking feeds.

Why this separation makes sense

Weather is a constant factor, but delays are a product of many moving parts—aircraft routing, crew availability, maintenance, ground handling, and air traffic flow. Keeping weather and operations separate reduces confusion and ensures each data type stays precise in its own lane. That way, a pilot can trust the METAR for weather while operations teams handle timing and logistics elsewhere.

Where METAR sits in the bigger weather picture

METAR is the weather observation backbone, but it doesn’t stand alone. It’s part of a broader ecosystem that keeps air travel safe and predictable.

• TAFs (Terminal Aerodrome Forecasts)

If METAR is a snapshot, TAF is the forecast version. While METAR shows what’s happening now, TAF looks ahead—useful for anticipating changes in wind, visibility, or cloud layers over the next 24 hours.

• Notams and notices to crews

These are notices about airspace restrictions, runway closures, or operational changes. They aren’t weather reports, but they drastically influence flight decisions alongside METARs and TAFs.

• Ground and air traffic updates

Real-time flight status, gate movements, and departure/arrival sequencing come from separate systems. Weather interacts with these, yes, but the weather data itself stays separate from scheduling.

A quick, practical read of a METAR

If you ever get a line like this in your weather feed, you’ll know where to focus:

KJFK 121651Z 27015G25KT 10SM -RA BKN020 OVC030 12/09 A2992

Here’s the mini-translation:

• KJFK: the airport (John F. Kennedy International, in this example)

• 121651Z: the observation time (12th day of the month at 1651 Zulu time)

• 27015G25KT: wind from 270 degrees at 15 knots, gusts to 25

• 10SM: visibility is 10 statute miles

• -RA: light rain

• BKN020 OVC030: broken clouds at 2,000 feet, overcast at 3,000 feet

• 12/09: temperature 12°C, dew point 9°C

• A2992: altimeter setting 29.92 inches of mercury

It’s a compact picture, but you can glean the big picture at a glance: wind, how far you can see, what the sky looks like, and whether rain or other weather is in play. The moment you notice lowering visibility or a rapid change in wind, you know there are decisions to be made—perhaps a different runway, a hold, or a cautious approach.

Common read-you-by lines and how to interpret them

• Wind from X degrees, Y knots

Flight operations depend on wind direction and speed. A crosswind on landing means you’ll need technique adjustments; a tailwind could alter takeoff performance. The numbers are there for you to translate into action, not guesswork.

• Visibility and weather phenomena

If the visibility drops, or if you see rain, snow, or fog indicators, you plan for instrument approaches, reduced visual cues, or potential deviations. Weather can escalate quickly, so the METAR read gives you the scoring sheet for that moment.

• Cloud bases

Cloud layers aren’t just “clouds.” They tell you about ceiling limits and how low you might be forced to fly if you must land under instrument conditions. Knowing the base heights helps you keep clear of restricted airspace ceilings.

A few digressions that still circle back

• Weather isn’t a static thing

On a sunlit afternoon, you can have near-perfect visibility. A few hours later, a front could sweep in and change everything. METARs refresh frequently enough to track those shifts, which is exactly what pilots and controllers rely on to stay safe.

• Weather and runway choices are linked

Sometimes it’s not just the weather that matters, but how a runway aligns with the wind. A headwind boosts takeoff and landing performance, while crosswinds demand more skill and a different approach. METAR data helps crews select the most forgiving runway when conditions are squirrely.

• It’s a team effort

Meteorologists from agencies like NOAA’s Aviation Weather Center prepare forecasts and observations. Airports feed METARs from automated stations or trained weather observers. Pilots interpret the data in the cockpit, and crews communicate with ATC in real time. It’s a coordinated ballet, with weather as the stage.

Tips to read METARs with confidence

• Start with the wind

Note the direction and speed, and check for gusts. A sudden gust can change approach speed and how you’ll hold the runway centerline.

• Scan visibility and weather together

If you see “RA” (rain) or “FG” (fog) or a drop in visibility, treat it as a signal to slow down, reassess approach performance, and confirm alternate plans if conditions worsen.

• Check cloud ceilings in sequence

Cloud heights affect minimums and instrument approach availability. If you’re curious about a conversion, you can mentally translate cloud bases into a ceiling that will affect your flight plan.

• Remember what METAR excludes

No flight status, no delays, no gate information. See those in separate sources so you don’t confuse weather with schedules.

Rounding out the picture for LAWRS learners

If you’re exploring LAWRS material, you’ll find METAR is a central thread. It’s the weather backbone that supports safer flight operations. Understanding what METAR includes—and what it does not—helps you interpret real-world weather with clarity. You’ll be better prepared to anticipate how conditions can influence takeoff performance, approach strategy, and flight safety decisions, all while keeping an eye on the bigger operational picture.

A gentle recap

• METAR gives you a current weather snapshot: wind direction and speed, visibility, cloud cover, weather phenomena, plus temperature, dew point, and altimeter.

• It does not include flight delays or scheduling information. Those belong to separate operational channels.

• For a forward-looking view, you pair METAR with forecasts (TAF), notices (NOTAMs), and real-time flight status feeds to understand the full picture.

• A quick read of a METAR, with practice, becomes second nature: you’re spotting wind shifts, visibility changes, and ceiling variations before the first stove-hot coffee cools down.

If you ever find yourself staring at a METAR line and wondering, “What does this mean for today’s flight?” remember this: the report is your weather compass for the moment. It tells you how the sky feels and what the air is doing, not how long a flight will be delayed. The two belong to different parts of the system, and together they help keep air travel as smooth and safe as possible.

And if you want to keep the concept alive in your mind, here’s a small mental trick: think W-V-C-W as a quick map—Wind, Visibility, Clouds/Weather, then the rest (temperature and pressure) that helps you fine-tune your understanding. It’s not a rule carved in stone, but a handy rhythm that makes METARs a little less intimidating and a lot more useful.

In the end, METARs aren’t about drama; they’re about accuracy, speed, and safety. They give the crew a shared, current view of the sky, so decisions can be made with confidence, not guesswork. That clarity is what keeps every leg of a journey from becoming a surprise, and that’s precisely the value of good aviation weather reporting.
