Vigo and Galicia feature birch (February-April), alder (January-March), milder grasses than the plateau and a plantain peak in May-June. Pine pollen abundant but poorly allergenic. WhatAWeather displays the typical calendar based on multi-year records of the Spanish Aerobiology Network (REA) coordinated by the SEAIC Aerobiology Committee (Spanish Society of Allergology and Clinical Immunology).
Pollen is the leading trigger of seasonal allergic rhinitis and allergic asthma in Spain, with a 21.5% prevalence in adults according to the Alergologica 2015 study. In recent decades climate change has lengthened and brought forward the pollination periods of several key species such as cypress and London plane, while intermittent drought intensifies grass peaks after spring rainfall.
This tool combines hourly weather forecast (temperature, humidity, wind and rain) with concentrations modelled by CAMS (Copernicus Atmosphere Monitoring Service) and the Aerobiology seasonal pattern in Vigo. It does not replace an allergist's assessment or individual medical diagnosis. Also check polenes.com from SEAIC and your regional network to validate the data.
