Pollen Count & Forecast for Shizuoka

Shizuoka’s spring allergy season (February–May) is dominated by Japanese Cedar (Cryptomeria japonica) and Japanese Cypress (Chamaecyparis obtusa); Cedar is prolific on the slopes of Mount Abe and the Nihondaira plateau; Cypress is common across the northern hills. Summer and autumn see high Grass (Poaceae) and Mugwort (Artemisia) counts; these originate from the banks of the Abe River and Warashina River.

The surrounding mountains and coastal winds trap pollen in the city basin. High humidity from Suruga Bay increases Mould (Alternaria, Cladosporium) spore counts throughout the rainy season and autumn; spores are common near damp tea plantations and coastal parklands.
