Families planning to celebrate the July 3 fireworks across the Mississippi River in the Dubuque area should be prepared for very warm summer weather. The annual July 3 Fireworks & Air Show is expected to draw large crowds along the riverfront for an evening of patriotic entertainment and fireworks.

The forecast calls for hot and humid conditions on Friday, July 3, with afternoon temperatures reaching the low 90s. A few afternoon thunderstorms are possible before evening festivities, so those attending should keep an eye on the latest forecast. By Saturday, July 4, conditions are expected to remain mostly sunny, humid, and hot, with highs again in the low 90s.

If you’re heading to the celebration, stay hydrated by drinking plenty of water throughout the day. The combination of heat and humidity can increase the risk of dehydration, especially if you’re spending several hours outdoors. Wear lightweight clothing, seek shade when possible, and check on children and older adults during the hottest part of the day. With fireworks, warm weather, and thousands of people expected along the riverfront, planning ahead and staying cool will help make for a safe and enjoyable Independence Day weekend.
