The destination weather pages on this site (Antigua, Lake Atitlán, Tikal, Acatenango) are model forecasts. Guatemala City also has an observing station: La Aurora International Airport (ICAO code MGGT), 6.4 km south of the city centre according to Wikipedia. In the 24 hours to 11 PM on 24 September 2026 it filed 31 reports: one on every hour, plus seven between the hours, five of them SPECI (unscheduled) reports (our feed file of that evening, saved in our research captures). This page shows what that station actually recorded over the last 24 hours, what the airport’s own forecast says for the next day, and, last, OpenWeather’s rain chance for each 3-hour step, so you can see observation and forecast side by side.

METAR (scheduled) and SPECI (unscheduled, issued when a significant change is observed) reports from station MGGT, read from aviationweather.gov. An observation, not a forecast. Temperature in °C (°F), wind in km/h (mph) converted from knots, visibility in km converted from statute miles; + means that distance or more. A dash (—) under weather means the report carried no present-weather group. For the latest report, open MGGT on aviationweather.gov.

How to read it. Each row is one report. Rows with a thunderstorm at or near the airport are shaded. The weather reported column decodes the report’s present-weather group using the aviationweather.gov code table: for example -RA is light rain, -TSRA a thunderstorm with light rain, VCTS a thunderstorm in the vicinity and BR mist. Cloud heights are above the airport, as the reports code them.

The TAF (terminal aerodrome forecast) is written for the airport and its surroundings. Rows whose forecast weather includes a thunderstorm (TS) are shaded. In aviationweather.gov’s guide, a TEMPO group marks temporary fluctuations expected to have a greater than 50 percent probability, to last one hour or less each time and to cover less than half of the period; a PROB30 group is a 30 percent chance of the event; an FM (from) group marks a significant change in prevailing conditions expected in less than an hour, and everything after it applies from that time. Other change codes (such as BECMG) are shown as the forecaster coded them, and the full original text is printed under the table.

OpenWeather's rain chance for each step of its forecast, which moves in 3-hour steps, at the La Aurora airport point. The thunder column says whether MET Norway's forecast symbol for those hours names thunder. A model, not an observation.

What this page is, and is not

  • One point. Every number here is for La Aurora airport. It does not describe every zone of the city, and it does not describe Antigua or the lake: see Antigua weather and Lake Atitlán weather.
  • Refreshed once a day. Our data pipeline reads the airport reports and the forecast once a day. The stamp above each table says when; if a day’s read fails, the previous data stays up and the stamp turns red after 26 hours. For the report issued in the last hour, open MGGT on aviationweather.gov.
  • Not an alert service. Official warnings come from INSIVUMEH and CONRED: see weather alerts today and, for tropical storms, the hurricane tracker.

Frequently Asked Questions

Is it raining in Guatemala City right now?

The first table on this page lists every report La Aurora airport issued in the 24 hours before the feed was pulled, with the weather it recorded (rain, drizzle, thunderstorm, mist). The page refreshes once a day, so for the report issued in the last hour use the aviationweather.gov link in the note under the table.

What is the difference between the airport reports and the forecast?

The METAR reports are observations: what the station at La Aurora measured and saw at that time. The TAF is the airport’s official forecast for roughly the next 24 hours. The rain chance at the bottom is OpenWeather’s forecast for the same point, in 3-hour steps, not an observation.

What does TEMPO mean in the airport forecast?

In aviationweather.gov’s guide, a TEMPO group marks temporary fluctuations expected to have a greater than 50 percent probability of occurrence, to last one hour or less each time, and in total to cover less than half of the period shown. A PROB30 group is the forecaster’s 30 percent chance of the event.

Does the airport weather apply to all of Guatemala City?

No. It is one station, at the airport south of the city centre. A report from La Aurora describes the airport, not every zone of the city.
