Windy conditions come from the atmosphere's response to heating at the surface. As the sun shines, the ground heats up faster than the air above it, causing the warm air to rise and air from surrounding areas to rush in to replace it. This creates convection and more vigorous mixing in the lower atmosphere, which translates to stronger winds. This heating and mixing peak around midday when solar energy is greatest and the surface is hottest, so winds tend to be strongest then. At night, the ground cools and the air becomes more stable, reducing vertical mixing and wind speeds. Dawn and dusk are transitional times with variable winds, not typically the windiest period. So, midday is the best answer because it aligns with the strongest surface heating driving the strongest wind.
