Today in New York Weather History: June 9


1915 (Wednesday)

Today's high/low of 81°/58° was preceded by two days with a high/low of 77°/60°, and would be followed by two days with highs/lows 77°/59° and 77°/60°.

1933 (Friday)

It was a hot and very humid day, with a high/low of 97°/76°.  The high was a record and the heat index reached 110° during lunchtime.

1973 (Saturday)

Today's high was 92°, the year's first day in the 90s and the first day of a four-day heat wave. 

1980 (Monday)

This morning's low of 47°, a record for the date, was the coolest reading in June in eight years - and there hasn't been a chillier reading since.

1984 (Saturday)

Today's high of 96° was the hottest reading of the summer, eighteen degrees above average.  It came in the midst of an early summer heat wave which lasted ten days (June 5-14).  The average high/low during these days was 91°/73°, twelve degrees hotter than average.  Six of the days were in the 90s.




1989 (Friday)

2.55" of rain fell today, with 0.75" of it pouring down between 11 AM-1 PM; another 1.15" fell between 8-11 PM.  This was a record amount for the date.  Furthermore, this was the sixth day in a row with rain, totaling 4.95". 

1997 (Monday)

Twenty of the past twenty-one days had below-average temperatures, resulting in temperatures that were six degrees below average.

2003 (Monday)

Four of the past five days had a low of 57°; the other day had a low of 58°.  Also, twenty-eight of the past thirty days were cooler than average.

2004 (Wednesday)

Today's high was 91°, which would be the hottest reading of the year, and the first of just two 90-degree days all summer (the other would be on Aug. 28).  2004 joined four other years that had 91° or 90° as their hottest reading: 1884, 1889, 1902 and 1960.  A typical New York summer has eighteen days with highs of 90+, and the hottest temperature is usually around 97°.




2008 (Monday)

Today was a scorcher, with a high/low of 96°/76°, sixteen degrees above average.  This was the third day in a row with highs in the 90s, and tomorrow would be the fourth.

2009 (Tuesday)

In just fifteen minutes time, in the wee hours of the morning, 0.75" of rain thundered down between 2:41-2:56 AM.  Rain continued until 8 AM and totaled 1.80".




2010 (Wednesday)

0.89" of rain fell, beginning early in the afternoon and continuing until a little past midnight, breaking a three-week dry spell in which only 0.11" of rain had fallen.

2011 (Thursday)

The day after a high of 93°, today's high reached a sizzling 95°.  Meanwhile, Newark, as usual, out-fried NYC, with highs of 99° and 102°, both which were records. 

2017 (Friday)

For the first time this month the high reached 80°, the deepest into June that the first 80°+ reading occurred since 2003, when it also happened on 6/9.  Additionally, this was the first reading in the 80s since the three-day heat wave of 5/17-19 ended.

2021 (Wednesday)

With a high of 90°, this was the fourth, and last, day of a four-day heat wave.  (And the day before the heat wave started, the high reached 89°.)  This was the first heat wave of this length in June since 2008.  And although that heat wave's average high was significantly hotter (95° vs. 91°), this June's heat wave had low temperatures that were significantly warmer (75° vs 70°).  It was also very humid, with dew points largely in the 68°-72° range, producing afternoon heat indices in the mid-90s.  With four days in the 90s through 6/9, this was the earliest date for that number of days since 2000, when the fourth reading in the 90s occurred on 6/2 (ironically, that year would have only seven in total).

You noted that "Newark, as usual, outfried NYC". I always wondered why.....


I believe two factors come into play: 1) Newark has no body of water to its west like Central Park does (Hudson River, New York Harbor), so winds coming from out of the west or southwest aren't cooled off, and 2) Central Park is surrounded by grass which holds moisture and suppresses the temperature somewhat, as opposed to concrete runways surrounding an airport which heat up more quickly.
