Lisbon, Portugal has a Mediterranean climate with mild, wet winters and warm, dry summers. Spring and fall are pleasant transition seasons.

Lisbon's pollen season typically starts in late February with tree pollen, followed by grass pollen in March and lasts until late September. Weed pollen can also be present year-round but is most common in the fall.

The city's location near the Atlantic Ocean moderates temperatures and humidity, with breezes helping to disperse pollen, which can be beneficial for allergy sufferers. However, increased air pollution in urban areas can worsen allergy symptoms.
