Stomata would be closed at the noon time to decrease the water loss through transpiration....
Also when sun sets each night, most terrestrial plants close their stomata. It is reasoned that plants open their stomata to acquire CO2. At night, with no photosynthesis, there is no need to acquire CO2, and so the stomata can close

In general, stomata open by day and close at night. During the day, photosynthesis requires that the leaf mesophyll be exposed to the air to get CO2. At night, the stomata close to avoid losing water when photosynthesis is not occurring
