Warmtegetallen sinds 1901 in De Bilt
Het warmtegetal is een maat voor de warmte in het tijdvak van 1 april tot en met 31 oktober van het genoemde jaar. Het warmtegetal wordt berekend door het aantal graden dat de gemiddelde etmaaltemperatuur van elke dag boven de 18,0 °C ligt, op te tellen. Een dag met gemiddeld over 24 uur een temperatuur van 20,2 °C draagt dus 2,2 bij aan het warmtegetal. Zo komen we uiteindelijk tot een totale som die het mogelijk maakt de warmte in het jaar te classificeren.Actuele stand 2024: 126.7 (t/m 31 oktober)
