Depending on the season, temperatures can reach extremes of heat and humidity in summer and a damp, wet cold in winter. During summer, visitors should wear light, comfortable clothing and shoes and use sunscreen, because high temperatures and humidity increase the risk of heat cramps, heat exhaustion, and heatstroke. During fall, visitors should have a light jacket available because temperatures can drop suddenly. Winter temperatures can range from mild to extremely cold.
