My concern is that it is affected by the sun leading to artificially high readings.

98° on July 5, 1999, August 3, 2001, August 8-9, 2001 is the all-time record.

Newark has reached 103°. That ties the June monthly record that was set on June 30, 2021.

The 100° at Westhampton ties that location's all-time high. That mark was set on July 5, 1999 and tied on July 6, 2010.

The New York Downtown station (KJRB) has reached 105. I am not confident in its reliability. Having said that, parts of the City beyond JFK Airport did reach 100° based on the NYC Micronet.

The prior June mark was 92° on June 21, 2012. However, the POR is very short (1998 start).

Thick tree cover for Central Park. Westerly winds are ideal for heating the Boston area, as the air warms upon descent from the Berkshires.

Boston has reached 100°, which ties the June monthly record.

A @LibertyBelldream come true: JFK: 102

Newark has reached 100° for the second consecutive day. That ties June 2025 with June 1943, 1994, and 2021 for the most such days in June. The two consecutive days are the earliest-season occurrence of two or more 100° or above days. The old record was set during July 3-4, 1898.

JFK has hit 100 for the first time on record in June. The previous June record of 99 was set on June 26, 1949 and tied on June 26, 1952, June 29, 1959, and June 30, 1964.

Islip has now reached 97F (36.1C). That breaks the June monthly record of 96F (35.6C) that was set on June 24, 1966 and tied on June 19, 1994.

Islip has now reached 96F (35.6C). That ties the June monthly record that was set on June 24, 1966 and tied on June 19, 1994.

Atlantic City, JFK Airport, Newark, Norwood, and Wilmington, DE have all reached 96° so far. The East remains on track for multiple 100° highs. JFK could see its first such high in June.

As of 9:30, many areas have reached or exceeded 90°. Those areas include Atlantic City, Boston, Islip, New York City-JFK Airport, Newark, Philadelphia, and Providence. Elsewhere, Frankfort, IN had a dewpoint of 82°.

Timing has an impact.

Final low temperatures for yesterday and preliminary low temperatures for today:

Below is a list of some of the locations reaching 100° or above in the East:

Actually, the coefficients of determination are very high in June: JFK: 0.51; LGA: 0.61; NYC: 0.55. For JFK and NYC, every degree increase in the June low translates into a 1.0 degree rise in the high. For LGA, every degree increase translates into a 1.1 degree rise in the high during June.

Plattsburgh reached 101° today. That tied the all-time record that was set August 5, 1955 and tied on August 1, 1975 and August 2, 1975.

Today's records and a preview of tomorrow's New York City area records:

Unfortunately, I can’t. The data should be available by 8 pm.

No. We’ll see if Philadelphia can still get there today.

Mount Pocono reached 93 setting a new June monthly record high.

Today was the appetizer for what could be a day of historic June heat tomorrow. Extreme heat is likely tomorrow and possibly Wednesday Temperatures will likely top out in the upper 90s in much of the New York City area and lower to middle 100s in the hot spots in New Jersey tomorrow. Numerous locations could challenge or set new June monthly temperature records. June Monthly Records: Bridgeport: 97°, June 9, 2008 Islip: 96°, June 24, 1966 and June 19, 1994 New York City-Central Park: 101°, June 29, 1934 and June 27, 1966 New York City-JFK Airport: 99°, June 29, 1949, June 26, 1952, June 30, 1964 New York City-LaGuardia Airport: 101°, June 26, 1952 and June 13, 2017 Newark: 103°, June 27, 1952 June 26, 1952 is currently the hottest June day on record in and around the New York City area. Out of the five stations from the above list that were operating in 1952, three reached or exceeded 100° on June 26, 1952 (Central Park: 100°, LaGuardia Airport: 101°, and Newark: 102°). All five reached 95° or above. Two stations also saw 80° or above lows: Central Park: 81° and LaGuardia Airport: 84°. Both the number of 100° highs and 80° lows is the highest on record for June for this five-station area. For June 26, 1952, the five-station average high was 99.4°, the average low was 78.2°, and the mean was 88.4°. The average high and mean are the highest on record for June. The average low is the second highest on record for June. June 21, 2012 was the second hottest day, overall, in this region. Its average high was 96.8°. Its average low was 78.4°. Its mean was 87.6°. That average low was the highest on record for June. The average high and mean were the second highest for June. The ENSO Region 1+2 anomaly was +1.0°C and the Region 3.4 anomaly was 0.2°C for the week centered around June 18. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.47°C and the ENSO Region 3.4 anomaly has averaged -0.03°C. Neutral ENSO conditions will likely continue through at least late summer. The SOI was +13.85 yesterday. The preliminary Arctic Oscillation (AO) was +1.425 today. Based on sensitivity analysis applied to the latest guidance, there is an implied 80% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.2° (1.2° above normal).
