Anyone ready for San Juan?

May be I am becoming too aclimatized to the Mediterranean climate but while day time temperatures have been comfortable in the shade, during the last week, nights have verged on being almost cool, (but at least we have not had any rain recently) given that the San Juan celebration is just two days away is it just here on the "Costa Tropical" or also in other areas which seem unseasonally chilly. Can't imagine that I will be going in the sea at midnight on Wednesday unless the temperature quickly increases a few degrees! Anyone planning on following tradition and going for a swim then?
