New York Climate – June 2026 Update
Top 5 Cities: New York City, Buffalo, Rochester, Yonkers, and Syracuse
New York experienced a significantly warmer-than-average start to summer, with the April–June 2026 period ranking as the 15th warmest on record in 77 years, with an average temperature of 13.07°C, an anomaly of +1.1°C above the 1961–1990 baseline. June 2026 itself was also notably warm, ranking 23rd warmest with an average temperature of 18.33°C, which is +1°C above the baseline. Maximum temperatures followed a similar trend, with April–June ranking 14th warmest at 19.46°C, a +1.3°C anomaly, and June 2026 ranking 22nd warmest at 24.78°C, a +1.1°C anomaly. Globally, land temperatures for June 2026 ranked as the 3rd warmest on record, and the April–June period ranked as the 2nd warmest, highlighting a widespread warming trend.
What changed
The past three months have seen New York experiencing considerably warmer conditions compared to its historical average. This regional warming aligns with a broader national and global trend, as evidenced by the global land temperature ranking 2nd warmest for the April–June period. New York's 3-month anomaly of +1.1°C places it 153rd out of 234 regions globally, indicating that while it is warmer, many other regions are experiencing even more pronounced warming. The Northeast US climate region, to which New York belongs, also saw a group mean anomaly of +1.42°C for the three-month period, with New York being slightly cooler than the group average.
What’s driving change?
A significant warming driver for New York this period is the strong El Niño event currently underway, with a weekly Niño 3.4 SST anomaly of +1.8°C as of July 1, 2026. This El Niño is forecast to persist and strengthen through the end of 2026, with a 100% probability of remaining in an El Niño state through October–December 2026. Historically, El Niño events typically bring warmer-than-average winters to the Northeast US, and while the primary impact is often felt in winter, a strong El Niño can influence summer weather patterns, potentially leading to hotter summers. Additionally, New York has experienced an unusual concentration of extreme weather events recently, with four wildfires and one flood event occurring in the past month, representing 100% of the annual total for both types of events. Wildfires, particularly those from Canada, have led to significant smoke and air quality issues in New York, with climate change contributing to drier forests and hotter summers that fuel these fires. Flash flooding also occurred in late June and early July, following a heatwave. More information on these events can be found at Extreme Weather tracker.
Looking ahead
The strong El Niño is expected to continue intensifying through 2026 and into early 2027, suggesting a likelihood of continued warmer-than-average temperatures for New York, particularly during the upcoming winter months, and potentially more severe weather systems.
