About Belém in December
Belém's wide-open riverside esplanade and proximity to the Tagus mouth give it Lisbon's most maritime-influenced microclimate, with persistent Atlantic breezes and frequent morning fog. The expansive green spaces of Jardim de Belém and the Jerónimos monastery grounds provide significant cooling, keeping summer temperatures 3–4°C below dense inland neighborhoods.
