Many of us over-water our garden without knowing it's actual requirement. This not only wasteful, also we're doing more work than we need to. Every plant have different water need over the time and it depends on many factor like temperature, humidity & wind speed. During summer the evapotranspiration rate is more than the winter and hence water demand more in warm climatic conditions.
This simple tool is based on ambient temperature and area of garden which will give you a good estimate on your water demand.

Daily Minimum Temperature (°C)
The best time to water is early morning before the temperature begin to rise. Early morning tends to be a time of lower winds and thus reduced evaporation.

Daily Minimum Temperature is the minimum temperature recorded during day time.
