Real Sociedad supporters will have the opportunity to enjoy the Copa del Rey final outdoors, despite a predominantly cloudy sky. For Saturday, mild temperatures are expected, with highs around 20 degrees Celsius, and no significant rainfall is forecast. However, in typical Gipuzkoan fashion, a light drizzle (sirimiri) might appear towards the late afternoon or evening, coinciding with the match, though it is not expected to dampen the festive atmosphere.

Friday's weather will set the stage for Saturday's conditions. Gipuzkoa will wake up to fog, which will gradually clear to reveal medium and high clouds throughout the day. The thermal sensation will be spring-like and pleasant, with maximum temperatures around 20 degrees along the coast and slightly higher inland. From midday onwards, a northerly wind could cause a slight drop in temperatures.

This pleasant feeling will continue into Saturday, albeit with slightly lower temperatures. Along the coast, highs will not reach 20 degrees, unlike previous days, while inland areas could see temperatures up to 22 degrees. The big day for the txuri-urdin will be meteorologically calm, inviting fans to enjoy the streets. Nevertheless, caution is advised, as cloudiness could bring some scattered showers in the second half of the day. Drizzle and umbrellas might be present at the final, but the rain will be light and not enough to spoil the event.

Sunday will also start with abundant cloudiness. Clear spells will appear in the morning, but as the hours pass, the sky will become overcast again, potentially leading to numerous stormy showers in the second half of the day.

And if Real Sociedad lifts the Cup on Saturday, Gipuzkoa will rally behind the team next Monday to welcome the players in the center of the provincial capital. Initial forecasts suggest that this reception might be marked by clouds and some showers, which is nothing out of the ordinary for the people of Gipuzkoa.
