New York City's humid continental climate creates opposite challenges by season. Summers are hot and muggy — July averages 29°C with 65% humidity, and the urban heat island pushes some neighbourhoods 3–4°C above surrounding areas. The ideal ventilation window is early morning (5–7 AM) before heat builds, and potentially late evening if overnight temperatures drop below 22°C.
Winters are cold, dry, and windy — actually the best season for indoor air quality management. Cold dry outdoor air lowers indoor CO₂ and humidity effectively with brief ventilation bursts, and the dry air reduces mould risk considerably.
New York's growing exposure to Canadian wildfire smoke in summer is a serious air quality concern. AQI can jump from 30 to 150+ in hours during smoke events — exactly what OpenWindow.live's real-time AQI monitoring is designed to catch before you open a window. This has become a practical reality for New Yorkers in recent summers.
In New York sind frühmorgens (5–8 Uhr) und spätabends (nach Sonnenuntergang) meist am besten, wenn die Außentemperatur unter die Innentemperatur fällt.
In den meisten Fällen ja. Lüften kann die Innentemperatur in 30 Minuten um 2–5°C senken, wenn die Außenluft kühler ist.
Über 80% wird die Luft beim Lüften schwül. Besser auf trockenere Stunden warten.
