The document outlines a school's procedures for determining indoor and outdoor play based on temperature and heat index. It notes that the school nurse takes temperature readings twice daily and that outdoor play is restricted when the temperature exceeds 40 degrees Celsius. It also details that students have a maximum of 20 minutes outside with access to shade and swimming lessons are the only activities held outside currently. The document concludes by reviewing the school's sun and heat policy which emphasizes staying hydrated, wearing hats and sunscreen, and following notices about outdoor play.

Dear Parents / Guardians,
We have been very fortunate in the sense that up until very recently the outside temperatures have not been as extreme as in previous years. However, as we head into the last three weeks of term we feel it is important to reinforce the approach we take to determine inside or outside play.
Procedure for monitoring the temperature and ensuring student well-being.
 Our PYP nurse takes the outside temperature twice a day using our combined thermometer/hygrometer, at 9:45am and 11:45am respectively. This is a measure of the air temperature together with the relative humidity. From this the Heat Index is calculated. Please see http://www.hpc.ncep.noaa.gov/html/heatindex.shtml as a reference.
 The heat index is an accurate measure of how hot it really feels when the effects of humidity are added to high temperature. It’s a measurement of the air temperature in relation to the relative humidity, used as an indicator of discomfort. The heat index is higher when high air temperatures occur with high humidity, and lower when they occur with low humidity. The heat index is based on studies of skin cooling caused by the evaporation of sweat. Also called apparent temperature.

 Whilst many other schools in Dubai do not adhere to any strict temperature guidelines and hence permit students to play outside throughout the school year, we at GCS (having consulted a Doctor and Dubai Health Authority) have installed an upper limit of 40 degrees centigrade as the cut-off point for outdoor play to ensure that our students’ prolonged exposure to the heat is restricted.
 The maximum time our students are outside is 20 minutes, during which they have access to several shaded areas at all times.
 Our PE Department follow the same procedure as above and only swimming lessons are currently being held outside.

2. Please take a moment to review our Sun and Heat Policy below.
Sun and Heat Policy
At Greenfield Community School we want staff and children to enjoy the sun safely. As we all know Dubai’s temperatures are very high. During the hot months be prepared for midday temperatures to reach to 42°C to 45°C (95°F to 108°F). On the hottest days the temperatures can reach 48°C (120°F).
To protect ourselves from the harmful effects of the sun, we need to:-
 Always wear a hat when outside
 Stay in the shade as much as possible
 Make sure you never burn
 Apply sun cream at home before coming to school
 Remember a water bottle for school and drink from it regularly
 Then observe the outside play notices
This will help you be A SMART sun child
