Spanish researchers have been investigating a longtime hypothesis of weather-watchers. The theory goes that human air pollution created during the week, when we all commute back and forth like madpeople, could cause an increase in rain on the weekends.

It turns out that, at least in Europe, the perception that weekends tend to be rainy more often may be supportable by long-term climate data. Correlating data from weather stations across Spain which was gathered between 1961 and 2004, the researchers found a pattern of fine weekdays and rainy weekends, and suggested that they might be able to point to weekly changes in air circulation across the broader landscape of Europe. (There goes that "rain in Spain" joke I was working towards...)

Travelers, take note: book your trips to Spain mid-week, or you might find yourself huddling in the rain instead of basking in the sun. (Or, don't book a trip to Spain at all, and cut down on the air pollution that causes the rain in the first place!)
