Asthma manifested by wheezing and breathlessness can be triggered by weather changes like a change in humidity, barometric pressure and temperature. It is possible that a change from dry to rainy or from hot to cold and vice versa caused your symptoms. This is a common problem that can be prevented with medication or by staying in places where you have less exposure to these elements. Since colds and other respiratory problems can also trigger asthma, you can lower your risk of attack also by preventing them or getting treatment.
