Almost an hour lasted the overthrow of the rain from the sky with hail. What is very pleasing in Pamplona is that the rainwater drainage system completely copes with the water flow. Several hours after the rain, and everything is dry - no puddles, no mud.
It would be fun to see such weather in the San Fermin period. And although July is already summer, but this is the north of Spain and during San Fermin (from 6th to 14th July) it is cold. The day can be 15-16 degrees Celsius, and at night the temperature can drop to 5-6 degrees.
Yesterday I looked at the "remains" of the apartments on airbnb for these dates - from 300 euros per day, the average price is about 800. Therefore, many tourists prefer to spend the night under the open sky, and such low temperatures can be a surprise.
