WeatherArb calculates Z-Score, HDD and CDD against the NASA POWER 25-year baseline for Amsterdam (52.37°N, 4.9°E). EN ISO 15927 standard.
Cos'è lo Z-Score climatico?
Misura quante deviazioni standard la temperatura attuale di Amsterdam si allontana dalla media storica dello stesso mese. Sopra +2σ indica caldo anomalo raro; sotto -2σ indica freddo anomalo.
Cosa sono HDD e CDD?
Heating e Cooling Degree Days, standard EN ISO 15927, misurano la domanda energetica per riscaldamento/raffrescamento confrontando la temperatura con una soglia di 18°C.
Con quale frequenza si aggiornano i dati di Amsterdam?
WeatherArb aggiorna i dati meteo di Amsterdam ogni ora tramite MET Norway, NOAA NWS e WeatherAPI.
Weather Amsterdam Today — Temperature and Climate Anomalies
WeatherArb monitors current temperature in Amsterdam against the NASA POWER 25-year climate baseline. When an extreme heat event, unusual rainfall or cold snap occurs, the Z-Score is automatically updated.
Humidity, wind speed and feels-like temperature in Amsterdam are updated hourly. During heatwave conditions (July: elevated heat anomaly risk), the anomaly level rises to EXTREME or CRITICAL — a statistically rare climate event.
A Changing Climate — Amsterdam
In the Amsterdam area, the mean annual temperature has risen by 1.1°C since 2001. Days with highs above 30°C went from an average of 0.0 in 2001–2010 to 1.1 in 2015–2024. The highest recorded value was 32.1°C (2019-07-24).
Methodology: Data comes from the NASA POWER reanalysis (MERRA-2) at roughly 50 km grid resolution: figures describe the surrounding area rather than a single urban station.
