This page documents all tornadoes confirmed by various weather forecast offices of the National Weather Service in the United States in June 2023. On average, there are 213 confirmed tornadoes during the month.^[1] These tornadoes are commonly focused across the Midwest and the central and northern Great Plains, and occasionally the Northeast, all due to their proximity to the late spring/early summer jet stream which continues to retreat farther north. Additionally, activity can sometimes increase in the Florida Peninsula as a result of early-season tropical activity.^[2]

The month began with relatively little tornado activity as there were only a small number of tornado reports in the first 10 days of June and all were weak. Thereafter, an unusual weather pattern for the season developed, with a displaced jet stream for mid-June resulting in multiple rounds of severe weather primarily across the Southern United States, which led to a significant increase in the month's tornado count. The weather pattern then shifted back northward, bringing more rounds of severe and tornadic weather to the Great Plains and Mississippi Valley in late June. During that period, well over 200 tornadoes occurred across the US. Overall, activity for the month finished somewhat above average with 252 tornadoes, making June the most active month of 2023 and the most active June since 2014.
