Frankfurt weather reports and daily highs since 2020

Each row is one METAR or SPECI weather report from Frankfurt (EDDF), since January 2020, via Iowa Environmental Mesonet. 117,227 reports of temperature, wind, pressure, visibility with the day's highest and lowest reading.

Coverage

• Window: 2020-01-01 to the most recent completed day, refreshed each morning. Report times are UTC; the calendar date is on Central European Time (UTC+1) all year, no daylight saving shift, so every day is the same 24 hours.
• Grain: one row per report; 2,443 days from 2020-01-01 to 2026-09-08 at the first build. Routine METAR reports arrive about hourly; special SPECI reports arrive when conditions change. A typical month holds 1,295 to 1,583 rows.
• Cadence: one new day of reports each morning; the day's high and low are final once the day's last report is in.
• Station: Frankfurt Airport, ICAO code EDDF, the station whose reports settle daily temperature questions for Frankfurt.

Columns

• station — the ICAO code of the reporting station, always EDDF.
• event_time_utc — the report time in UTC.
• observation_type — METAR for a routine report, SPECI for a special report.
• local_standard_date — the calendar date on Central European Time.
• temp_f, dewpoint_f — air temperature and dew point, degrees Fahrenheit. temp_c — air temperature, degrees Celsius.
• relative_humidity_pct — relative humidity, percent.
• wind_direction_degrees, wind_speed_kt, wind_gust_kt — wind direction clockwise from true north, sustained speed and gust, knots.
• altimeter_inhg, sea_level_pressure_hpa — altimeter setting in inches of mercury and sea-level pressure in hectopascals.
• sky_cover_1 to sky_cover_4, sky_base_1_ft to sky_base_4_ft — up to four sky-cover layers with their base height in feet.
• visibility_miles — horizontal visibility, statute miles.
• weather_codes — present-weather codes such as RA, SN, FG, TS.
• precipitation_in_1h — one-hour precipitation, inches.
• peak_wind_gust_kt, peak_wind_direction_degrees, peak_wind_time — peak wind from the report remarks.
• snow_depth_inches — snow depth, inches.
• raw_metar — the original report text.
• metar_high_f, metar_low_f, metar_high_c, metar_low_c — the highest and lowest temperature in any report on the same calendar date, in Fahrenheit and Celsius, derived from the rows.
• cli_high_f, cli_low_f, cli_product, cli_report_type — always null: no National Weather Service climate report exists outside the United States. Kept so every city table shares one schema.

Missing values

Absent fields are null, never zero. A trace of precipitation is null. Sky layers beyond those reported are null. The derived daily range is null only on a day with no parsable temperature.

Suitable for

• Reading the day's highest and lowest reported temperature at EDDF for any date since 2020, in Fahrenheit and Celsius.
• Reconstructing Frankfurt conditions at any hour since 2020.
• Building daily temperature, wind and precipitation series for Frankfurt Airport.
• Checking what EDDF reported around a settlement time or a forecast.
