I'm planning on a family trip to Orlando Florida sometime in September.
I hear that it rains alot in Orlando during the month of September.
I visited the following websites to find out if there was a rain
pattern for the month of September in Orlando.
1) weather.com - http://www.weather.com/weather/wxclimatology/daily/USFL0372?climoMonth=9&x=9&y=8
2) weather.gov - http://www.weather.gov/climate/index.php?wfo=tbw

I'm having a hard time finding the "Daily rain archives" I see the
average high and low temperatures for each day for the month of
September for the last 30 years, but I can't find whether it rained
during that particular day or not. Can anyone help me?
