How weather affects long covid
Not every weather factor hits every condition the same way. These are the inputs our Long COVID scoring model weighs most heavily — and in San Francisco (West Coast), they interact with the local climate pattern: Seattle, San Francisco, and Los Angeles — Pacific coast weather trends and body-forecast scores.
Air quality
28% of scoreLong COVID patients with persistent respiratory symptoms are especially vulnerable to air pollution, which can worsen breathlessness, cough, and chest tightness.
Heat index
22% of scoreMany Long COVID patients develop autonomic dysfunction (including POTS), making heat intolerance a significant trigger for fatigue, tachycardia, and brain fog.
Barometric pressure changes
22% of scoreWeather sensitivity is commonly reported in Long COVID, with pressure changes triggering headaches, fatigue, and cognitive symptoms similar to ME/CFS.
Daily temperature swings
16% of scoreUnstable weather conditions require physiological adaptation that can trigger post-exertional malaise and fatigue crashes in Long COVID patients.
Humidity
12% of scoreRetained at reduced weight for non-thermal effects: humidity independently affects airway moisture and respiratory comfort, which is particularly relevant for Long COVID patients with persistent lung involvement.

Felt That is not a medical service. Forecast scores describe weather conditions associated with symptom changes in published research and community-reported patterns — they are not medical advice, diagnosis, or treatment. Individual responses to weather vary widely. Always consult your healthcare provider about managing your condition.
