Manchester and Nashua Record Highest Temperatures in New Hampshire

Parts of southern New Hampshire experienced summerlike heat on April 14, 2026, with temperatures exceeding 80 degrees for the first time since October 7, 2025.

According to reporting from WMUR, the warmth was nearly 30 degrees above the average temperature for this time of year. Nashua recorded the highest temperature in the region at 86 degrees, while Manchester reached 85 degrees.

Other cities in the state also saw temperatures in the 80s. Concord and Keene both reached 83 degrees, and Lebanon and Jaffrey recorded highs of 81 degrees.

The spike in temperature occurred after a period of 189 days since the region last saw temperatures of 80 degrees or higher.

While the warmth was significant for the date, it did not break any state records. The all-time highest temperature ever recorded in New Hampshire was 106 degrees, which occurred in Nashua on July 4, 1911.

Regional Temperature Variations

The heat was primarily concentrated in the valley areas of southern New Hampshire. In contrast, coastal areas remained significantly cooler, with temperatures in the 50s along the beaches and shore roads during the afternoon of April 14, 2026.

Historical Weather Context

The recent temperatures in Manchester and Nashua remain well below their historical maximums. In Manchester, the highest temperature ever recorded was 105 degrees on August 3, 1988.

Data from the NOAA’s State Climate Extremes Committee (SCEC) provides further context on the state’s temperature extremes. Beyond the record high in Nashua, New Hampshire’s all-time lowest temperature was -50 degrees, recorded at Mount Washington on January 22, 1885.

Mount Washington has also been the site of other significant weather records, including an all-time high 24-hour snowfall of 49.3 inches on February 25, 1969, and an all-time high 24-hour precipitation record of 11.07 inches on October 20, 1996.
