Install bamboo shades or porch blinds to block out the sun's rays and keep the space cooler. When the sun stops filtering through, pull the shades back up to enjoy the outdoor view.
Install a ceiling fan in the center of the outdoor patio, or place an oscillating fan at one end of the porch to circulate air and cool the space.
Set a small outdoor table fountain on the patio. The refreshing sound of bubbling water helps promote a cooling atmosphere.
Place large potted plants around the perimeter of the patio. Large plants block the sun's rays while allowing cool breezes to filter through.
Use low-watt yellow bulbs for outdoor lighting at night. The yellow bulbs attract fewer bugs than white lights, and the lower wattage gives off less heat.
