Being so close to the sea, the Sueve range is greatly influenced by the maritime climate. Temperatures are moderate year-round, with gentle summers and wet winters, lacking the strong contrasts of areas further inland. Clouds coming from the sea can condense on the northern slopes, cloaking them in thick fog, and giving that area a higher annual rainfall than anywhere else along the Asturian coast. The southern slopes of therange, above Arriondas, enjoy a warmer drier climate due to the rain-shadow effect of the range itself, and to their southern orientation. While the northern side is prone to sea fogs, thesouthern side commonly experiences valley mists, especially in the early morning, usually foretelling of a glorious day ahead. It is quite common for the coastal and inland sides of the Sueve to experience very different weather on the same day, with rain or cloudon one side but not the other.
A good indicator of weather on the southern slopes of the range is the "Canal del Fito", the small valley separating the Fito hills from the Sueve range. When cold wet air moves inland from the coast it fills this small valley, before spilling over the Fito hills and down the southern slopes ofthe Sueve. When seen in late afternoon or early evening this predicts good weather tomorrow, but seen in the morning it could mean rain onthe way.
While the Sueve often gets a sprinkling of snow in winter, it gets far less than mountains further inland, and the snow doesn't linger long due to warm sea breezes.
