Traveller notes on Santander in January
Other months in Santander
Santander's forum describes July as mild rather than hot by Spanish standards, with beautiful sunshine possible but never guaranteed on the Bay of Biscay coast. Regulars are candid that this 'Green Coast' region stays damp and humid much of the time thanks to the surrounding mountains, and that a morning drizzle turning to afternoon sun (or the reverse) is a completely normal pattern.
