If Saturday seemed like a real scorcher, it wasn’t just the heat going to your head. According to National Weather Service Boise, the Treasure Valley broke a nearly 50-year-old record for high temperatures recorded on July 8.
Just after 5 p.m., temperatures hit a high of 104 degrees, inching over the previous July 8 record that the Boise area has seen only twice in record-keeping history. Exactly 100 years ago on July 8, 1917, Boise weather-watchers noted down high temperatures of 103 degrees. In 1968, the Treasure Valley also endured 103-degree temperatures.
This time of year it’s normal for temperatures to hover around 90 degrees, explained Elizabeth Padian, a meteorologist with the Boise NWS.

Is more record-breaking heat on the way? Not likely, Padian said. As record high temperatures go, July 8’s 103 degrees was low-hanging fruit. Temperatures would really have to soar above projected highs of 100 degrees on Sunday to beat another record.
On Monday and Tuesday we’ll see some respite, Padian said. High temperatures for those days are expected to be 94 and 91 degrees, respectively. Later in the week, temperatures will “climb rapidly to near 100” again, Padian said.
The meteorologist said a ridge of high pressure to Idaho’s southeast is what’s keeping temperatures warm here, along with causing thunderstorms, particularly in the Magic Valley. Those types of systems are not unusual for summertime in Idaho, Padian explained.
