Barcelona, Spain has a Mediterranean climate with mild, wet winters and warm, dry summers. Spring and fall are transition seasons with varying weather.
Barcelona's pollen season typically starts in late February with tree pollen, followed by grass pollen in May and weed pollen in June. Levels vary yearly, influenced by temperature, rainfall and wind.
Winds from the sea can bring relief from pollen, but onshore winds can increase pollen concentrations. Allergy sufferers should monitor pollen forecasts and limit outdoor activities during peak times.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
