About lightning in Portugal
Portugal's lightning peaks in the shoulder seasons. Autumn and spring bring Atlantic cold fronts across a still-warm sea, firing thunderstorms along the coast from Lisbon to Porto, while summer stays mostly dry. Inland and northern areas see more frequent storms than the south. Because these storms move fast off the ocean and strike ahead of the rain, the live distance to the nearest flash — and whether it is approaching — beats waiting for thunder.
