Your Weather Chart

Your Weather Chart

Now that you have collected temperature and precipitation data, it is time to put it all together by creating a weather chart.

Having a weather chart will help you organize all of the weather data you collect. Make sure you fill out your weather chart at the end of every day that you collect data.

Here is an example of a weather chart that has been filled in.

Weather Chart

Draw your own weather chart or print off the one we made. You will need one weather chart for the week.

For weather observations write down anything you notice about the weather for that day. Answer questions such as:

  • Was it cloudy? What did the clouds look like?
  • What colour was the sky?
  • Was it windy? What direction was the wind coming from?
  • Was it sunny or dark?
  • Did it feel hot or cold outside?
  • Did it rain or snow?
  • Was there a storm or some type of big weather event?

To fill in "temperature" section look at your Temperature Chart for the day. Write down the highest temperature and the lowest temperature.

To fill in precipitation look at your Precipitation Chart. Write down the amount in centimeters (cm). If it rained, put an "R" beside the amount. If snowed, put an "S"' beside the amount. If it didn't rain or snow, write down 0.

If there is a day that you didn't take weather observations and measurements write down "DK" for "Don't Know" for that day.

At the end of the week, figure out the "average temperature" and the "average percipitation." To get the "average temperature," add up all of the temperatures you wrote down. Divide the total by the number of times you wrote down a temperature for the entire week. To determine the "average high", add up all of the "high temperatures" and divide the total by the number of days that you have data for. To figure out the "average low," do the same thing but with the "low temperatures."

To figure out the "average precipitation," add up the amount of rain or snowfall from each day and divide the total by the number of days you have data for.

Average Temperature

= (12+5+13+4+12+4+
17+7+14+4+11+3+
11+2)÷14
= 119÷14
= 8.5°C

Average High

= (12+13+12+17+14+11+11)÷7
= 90÷7
= 12.9°C

Average Low

= (5+4+4+7+4+3+2)÷7
= 29÷7
= 4.1°C

Average Precipitation

2+0.5+0+0+1+0+0
= 3.5 cm
= 3.5÷7
= 0.5 cm
