The weather affects my RA in that if it's too cold it hurts. Also if it gets too hot it hurts too. Then also if it's too dry it can trigger my RA. Come to think of it if it's too humid it can trigger my RA too. So lets just say that if the temperature and humidity isn't exactly right, things can go wrong - sufficed to say you are not alone! My best tip is don't set the air conditioner or heat too high and invest in a humidifier. It can help to maintain the environment best suited to your RA! Keep on keepin' on, DPM
