The official start date of summer may be a few weeks away, but the temperatures are heating up, with the heat index projected to reach more than 100 degrees this weekend.
The forecasted high temperatures are expected to reach the mid and upper 90s today and Sunday with heat indexes of 102 and 108 degrees, respectively.
According to the National Weather Service, the heat index tells how it feels outside when the relative humidity is included with the actual air temperature.
Based on the NWS heat index chart, a feels-like temperature of 108 degrees is in the danger category.
Sunday’s high of 97 degrees will be the hottest day of the year so far, but it does not set a record for June 9. That was set in 1917, when the thermometer showed a reading of 100 degrees.
Though a cold front will drop next week’s temperatures into the upper 80s and lower 90s, the upper 90s are expected to return next weekend.
According to the NWS, people should limit strenuous outdoor activities during the day, especially between 10 a.m. and 4 p.m., when the sun’s rays are strongest. When outside, people should find shade and stay hydrated.
The service also suggests people check on the elderly and sick, as well as those without air conditioning.
Finally, the NWS promotes a “look before you lock” mentality to ensure children and pets are never left unattended in cars.
According to a San Francisco State University graph, a turned-off locked car in direct sunlight on an 80-degree day can go from 80 degrees inside the car to 123 degrees in one hour.
In two minutes, the university found, the vehicle can go from 80 degrees to a dangerous 94.3 degrees Fahrenheit. Within 10 minutes the temperature reached 99 degrees.
Objects in the car, such as the dashboard, steering wheel and child’s car seats, can get even hotter, reaching temperatures of between 180 and 200 degrees Fahrenheit.
Leaving windows cracked does not make a significant impact in how hot the interior of the cars get, the NWS notes.
When it comes to heat safety, there are signs people can look for to identify heat exhaustion and heat stroke.
A NWS graphic lists the symptoms of heat exhaustion as feeling faint or dizzy; excessive sweating; cool, pale or clammy skin; nausea or vomiting; a rapid, weak pulse; and muscle cramps.
If someone is showing signs of heat exhaustion, they should get to a cooler, air-conditioned location, drink water if fully conscious and take a cool shower or use a cold compress, according to the service.
The Centers for Disease Control and Prevention also encourages people to get immediate medical help if the person is throwing up or if the symptoms get worse or last longer than one hour.
Heat stroke symptoms are identified as a throbbing headache; no sweating; a body temperature of more than 103 degrees with red, hot, dry skin; nausea or vomiting; a rapid, strong pulse; and possible loss of consciousness.
If someone shows signs of heat stroke, the best course of action, the NWS states, is to call 911 and take immediate action to cool the person until help arrives.
People should not try to give someone suffering a heat stroke anything to drink.
