Answer:
Long-term climate data.
Step-by-step explanation:
Any data, whether precipitation, clouds or extreme weather data over the past 30 days doesn´t serve you when you´re moving to a place where you are going to live for years to come. Example, when you take the 30 days of july in Mexico you probably won´t move because of the rain season in the summer. But apart from these 2 to 3 months, the rest of the year you have sunshine all year around.
