Another heatwave is on the way for Adelaide, with temperatures set to rise above 40 degrees by the weekend.

From tomorrow, temps will start to creep into the mid-thirties and will peak to 41 for three days from Saturday.

And the nights will be very warm, with the mercury not expected to fall below the mid-twenties.

Dick Whitaker from The Weather Channel says we'll have to be patient for the extreme heat to go away. The cause of the heatwave is due to a very hot mass of air drifting slowly south from central Australia.

Here are some Tips to keep cool if you don't have airconditioning

Windows
Windows and blinds should be closed while the sun is up. Keeping windows and doors closed up will allow the house to stay as cool as possible for the longest amount of time.

Head downstairs
Stay downstairs can also keep your cooler. Heat rises so the upper floors of your household so staying downstairs makes a big difference. If you have a basement you should consider taking breaks during the daytime to get a break from the heat.

Water and Ice
Water is a great way to cool off. Take a cool bath or shower during the day. You can also soak your feet in an ice bath to cool down. Get a spray bottle that is filled with cold water and spray bursts on your face and neck throughout the day.

Lights out
Keeping unnecessary lights on in your home can actually raise the temperature of your indoor air. Also avoid using ovens and stoves during the day which can also up the heat factor during a heat wave.

Go out
On the days that are the hottest you should take advantage of your local businesses that have air conditioning.

Also keep in mind that pets are affected by heat. Make sure that you keep there safety and comfort in mind. Avoid eating large meals since they will make your metabolism increase which will raise your body temperature.

Dehydration and even death can occur from not taking necessary precautions during a heatwave. Make sure to check on elderly neighbours and relatives during heatwaves also. The elderly are especially susceptible to heatwave related illnesses. Keep yourself cool this summer and have fun in the sun but do it safely.
