Washington celebrated the 250th anniversary of U.S. independence on Saturday with fireworks and official events despite a dangerous heat wave [1, 2].

The milestone anniversary, known as the semiquincentennial, represents a historic national landmark, but extreme weather forced officials to prioritize public health over tradition.

City officials canceled the traditional July 4 parade after temperatures in the region surpassed 100°F [3, 4]. The decision came as a severe heat wave swept across the country, with some areas reporting maximum temperatures as high as 46°C, or 115°F [5].

Despite the cancellation of the parade, President Donald Trump organized a fireworks display at the National Mall [2]. The event was described as an unprecedented spectacle intended to commemorate the 250 years of independence [2].

Safety concerns extended beyond the weather. Prior to the holiday, officials removed 100,620 fireworks across the U.S. due to defects that posed a risk of accidental explosions [6]. This mass recall occurred as the nation prepared for the high-profile celebrations in 2026 [1].

The National Mall served as the primary hub for the remaining activities, where crowds gathered to observe the festivities while navigating the extreme heat [2, 3]. Local authorities said the temperature peaked during the holiday week, posing a risk to public health [4, 5].
