The Loo (Hindi: लू, Urdu: لُو‎, Punjabi Gurmukhi: ਲੂ) is a strong, hot and dry summer afternoon wind from the west which blows over the western Indo-Gangetic Plain region of North India and Pakistan. It is especially strong in the months of May and June. Due to its very high temperatures (45 °C–50 °C or 115°F-120°F), exposure to it often leads to fatal heatstrokes. Since it causes extremely low humidity and high temperatures, the Loo also has a severe drying effect on vegetation leading to widespread browning in the areas affected by it during the months of May and June.
