1896 (Monday)
This was the last day of a seven-day streak with very mild temperatures, with an average high/low of 81°/61°. This followed a six-day stretch ending 4/8 that experienced a cold average high/low of 41°/29°.
1927 (Wednesday)
The day after a pleasant high of 64°, today's was a summer-like 90°, nearly 30 degrees above average, and a record for the date (which still stands). At the time, it was the second earliest date for a 90-degree reading (on April 18, 1896 the high was 90°). After today it would be seven weeks before the next 80-degree reading was reached and the next 90-degree high wouldn't be until July 13.
1972 (Thursday)
The temperature at 4 PM was a quite chilly 43°, a drop of forty-three degrees from yesterday afternoon's 4 PM reading of 86°.
1990 (Friday)
Although showers that fell between 11 PM and midnight amounted to just 0.02", it was the first measurable precipitation to fall on this date since 1978.
2005 (Wednesday)
Today's high and low of 87°/64° was 22 degrees above average, making this the warmest day of the month. It would be seven weeks before a hotter temperature was reached (93° on June 8).
2006 (Thursday)
Today's high of 83° was the warmest reading of the month (and came five days after the year's first reading in the 80s), but what was even more notable was the afternoon's bone-dry humidity, which fell to 10% at 4 PM. Air this dry in NYC is rare. (Typical late afternoon humidity in April is around 45%.)
2009 (Monday)
Rain during the PM hours amounted to 1.79", with 0.87" falling between 8:19-10:19 PM. More precipitation fell today than in the entire month of March (1.75"). Temperatures were on the chilly side, with a high/low of 50°/42°, ten degrees below average.
2015 (Monday)
Dreary, windy, and damp, with rain thru early afternoon that amounted to 1.37". This was comparable to the amount that fell in the previous 30 days (and it was the biggest rainstorm in three months). After the wind died down, fog rolled in during the afternoon. Today's rainfall accounted for nearly two-thirds of April's total precipitation (2.08").
2016 (Wednesday)
Today was the seventh day in a row with clear skies and unusually dry conditions, with relative humidity below 20% during the afternoon and early evening (normal is in the 45%-50% range). And today saw the lowest humidity level of all the days, as it bottomed out at 9% at 6 PM - very similar to ten years earlier on this date.
2025 (Sunday)
It was a beautiful Easter Sunday, with nary a cloud in the sky. Afternoon temperatures were slightly above average, rising into the upper 60s (however, the day's official high was 73°, occurring between midnight and 1 AM). Late in the afternoon the humidity fell to 15%, which was similar to the humidity level on Easter Sunday two years ago.
