You can almost hear the jokes already — it’s so hot chickens are laying hard-boiled eggs and cows are giving evaporated milk. That’s because for the next week, Baton Rouge can expect temperatures to approach or exceed 100 degrees, with the heat index zooming even higher.

Baton Rouge is looking at four days of temperatures hitting 100 degrees or more, only getting slightly cooler Wednesday when the high is expected to be near 97.

On Saturday, temperatures are forecast to reach 100 degrees, 101 on Sunday, 101 on Monday and another 100-degree day on Tuesday, bringing the hottest temperatures of the year to the area.

It’s important to note that these are the expected temperatures in the shade. When combined with humidity or standing in direct sunlight, it will feel much hotter.

The heat index, or how hot it feels when temperature and relative humidity are combined, could be up to 109 on Saturday, 110 on Sunday and 112 on Monday.

With school back in session, East Baton Rouge Parish Superintendent Warren Drake contacted principals and district departments with information on preventing heat illness and asked leaders to limit outdoor activities.

Part of the cause of the high temperatures is a large high-pressure dome over the area that limits cloud cover and rain, which would help bring the temperature down, said Tim Destri, meteorologist with the National Weather Service in the New Orleans/Baton Rouge office.

Temperatures won’t dip far overnight, reaching only the upper 70s or even lower 80s, according to the forecast.

“As a result, we are just baking in the sun day after day,” said Barry Keim, state climatologist. “There’s something about hitting the triple digits that just breaks your spirit.”

It’s the continuation of what has been a hotter summer compared with the last two years. In 2013, there were only three days when the temperature got to 96 degrees or above and in 2014, only two days.

So far in 2015, there have been 18 days of temperatures of at least 96 degrees, with some days registering 98, 99 or even 100 degrees, Keim said.

High temperatures like what’s expected in the coming week mean people need to take precautions. That includes wearing lightweight and light-colored clothing, drinking plenty of water, wearing sunscreen and making sure to never leave a child or pet in the car, even for a short time.

For people working outdoors, drink two to four cups of water every hour regardless if you’re thirsty. If possible, do work early in the morning or late in the afternoon and take frequent breaks.

“These are oppressive, dangerous temperatures,” Keim said. “My advice to anyone with outdoor activities planned is be smart about it.”

Symptoms of heat-related illnesses include weakness, fast and weak pulse, nausea, fainting or heavy sweating. Anyone suffering from these symptoms should get to a cooler location, apply cool and wet cloths to the body, and sip water, according to the Centers for Disease Control and Prevention.

The more serious heat stroke has symptoms of a body temperature above 103 degrees, rapid and strong pulse and possible unconsciousness. If someone experiences these symptoms, 911 should be called, as well as moving the person to a cooler place but not giving them fluids, according to the CDC.

For people trying to beat the heat, pools, splash pads and BREC’s Liberty Lagoon Waterpark will be popular attractions this weekend. A special last day of the season event is scheduled from 3 p.m. to 6 p.m. Aug. 23, where up to 100 dogs will be allowed to join in the fun as well.

BREC splash pads are open from 8 a.m. to 8 p.m. at City-Brooks Community Park, 1515 Dalrymple Drive; Forest Community Park, 13900 S. Harrell’s Ferry Road; Greenwood Community Park, 13350 La. 19, Baker; Highland Road Community Park, 14024 Highland Road; and Jackson Community Park, 12250 Sullivan Road, Central.
