It Was an Ideal September

    September was “an ideal late-summer month,” Richard G. Hendrickson wrote in his monthly weather report from Bridgehampton.       

     Mr. Hendrickson, a United States Cooperative weather observer, recorded daytime highs in the 70s during the first half of the month and mainly in the 60s in the second half. Nights began mainly in the 60s, then dropped mostly into the 40s by month’s end.

    The hottest day last month was Sept. 11, when it was 85 degrees. The coldest temperature of the month was 38 degrees on the 18th.
    Mr. Hendrickson recorded measurable rain on four days, with the heaviest — 3.35 inches — falling on Sept. 3. The total for the month was 5.13 inches, quite a difference from September 2004, when he recorded a whopping 11.13 inches of rain. “Many people had a cellar full of water or overflowing,” he recalled.

    There were 10 clear days last month, 5 partly cloudy, and 14 cloudy.
