Why is it still cold in may?

Cold weather in May can occur due to various factors, including lingering effects of winter, regional climate patterns, and geographical location. In some areas, late-season cold fronts can bring chilly air, while higher elevations may still experience snow. Additionally, variations in ocean currents and atmospheric conditions can influence temperature, leading to unseasonably cool weather. Local phenomena, like the jet stream positioning, can also contribute to these fluctuations.
