Stockholm has a cold oceanic climate — mild by high-latitude standards but persistently cool, grey, and damp. Summer highs typically reach 18–24°C with long daylight hours; winters hover near or just above freezing with frequent overcast skies. The year-round moderate temperatures mean ventilation is rarely an emergency decision in either direction: outdoor air is almost never dangerously hot and rarely too cold to open briefly.
The primary ventilation challenge in Stockholm is humidity. Maritime cold air carries substantial moisture, and indoor humidity management matters more than temperature. On cold, damp days common from October through March, opening windows for extended periods raises indoor moisture and can cause condensation on cold surfaces. Burst ventilation — 5 minutes fully open — achieves complete air exchange without sustained moisture loading, and is the standard technique. Summer is the most straightforward ventilation season: long daylight hours and mild temperatures make extended ventilation comfortable on the warmest days. Air quality in Nordic and cold oceanic cities is generally excellent by global standards, with clean Atlantic air and low industrial pollution. The main exception is occasional temperature inversions in winter; OpenWindow.live tracks real-time AQI for those episodes.
À Stockholm, les meilleurs moments pour aérer sont généralement tôt le matin (5–8h) et le soir tard, quand la température extérieure passe sous celle de l'intérieur.
Oui, dans la plupart des cas. Ouvrir les fenêtres peut faire baisser la température intérieure de 2–5°C en 30 minutes si l'air extérieur est plus frais.
Au-dessus de 80%, ouvrir les fenêtres rend l'air collant. Mieux vaut attendre des heures plus sèches.
