With a low temperature of 52°F on Thursday, Dubuque tied the daily record for 23 July. The featured chart presents the daily high and low temperature climatology for Dubuque along with the 2026 observations. Any set or tied records are denoted with the small dot. What's interesting about Thursday's record is that the value is also the warmest minimum low temperature record for the site. So perhaps you may consider it as the easiest low temperature record to tie during the month of July. That aside, our very enjoyable respite from typical Iowa summer weather ends on Saturday, so hopefully you can enjoy the nice temperatures today!
