Among allergenic trees nearby, olive leads, followed by ash. Compared with most places, olive is especially widespread here, which makes it one of the key local allergens.
Olive and ash lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grass pollen follows, peaking in late spring and easing off by early fall. Pigweed and plantain bring a final peak from early summer into early fall. The olive period in late spring is usually the most intense time of year here.
