The area surrounding Waukesha County is anticipated to have extremely high temperatures this coming weekend. Saturday, June 21 and Sunday, June 22, the temperature is expected to hit 90 degrees, with the ‘Feels Like’ temperature being either at or over 100 degrees. High levels of humidity may also play a factor in the intense heat. Even in the evenings, temperatures may not fall below the mid 70s, meaning that there will be little nighttime relief.
If the temperatures rise as high as they are expected to, this would be the warmest that southeastern Wisconsin has been so far in 2025. As a result, citizens should be prepared for the heatwave’s effects.
As with any major rise in temperature, it is important to be well informed about the potential for health risks. Prolonged exposure to high temperatures may increase the risks of heat exhaustion or heat stroke. These are often characterized by heavy sweating, dizziness, nausea, and headaches. Individuals suffering from these symptoms should be given immediate medical attention, especially if they become confused or lose consciousness. Children, older adults, and those with chronic illnesses are at the greatest risk of having health related complications due to heat, and should exercise extreme caution.
Although the heat may be intense, there are several ways to stay safe and cool. It’s important to drink plenty of water during this time, as staying properly hydrated reduces the likeliness of illness. Avoiding beverages such as alcohol, caffeine drinks, and sugary drinks may be helpful, as these drinks increase the risk of dehydration.
Staying cool is extremely important, and having access to air conditioning may be crucial to staying safe. For those with AC units in their home, it is recommended to use them during these periods of high heat. Other spaces, such as the Waukesha Public Library, may also offer cool spaces. Indoor fans will provide direct spacial relief. If you have to spend time outside, limit it as best as possible and void direct sunlight.
The National Weather Service may issue a Heat Warning if the heat index (Which factors in humidity, and is best represented by the ‘Feels Like’ temperature) reaches 100 degrees or higher. If a Warning is issued, ensuring public safety is of the utmost importance. Currently, temperatures are expected to be in the mid- to high- 90s through the weekend.
