During late summer months (June through September) caution is advised while recreating in Big Thicket. The combination of high temperatures and humidity create extreme heat indices that can lead to heat stress or heat stroke. For example, an air temperature of 95° F and a relative humidity of 65% equates to a heat index of 114° F.
To avoid heat stress you should acclimatize yourself to the environment you are visiting. Avoid outdoor activities between 11 a.m. and 3 to 4 p.m. An early morning or late afternoon hike is much wiser during the summer months. Drink plenty of water; keep yourself hydrated. Wear a wide-brimmed hat, light clothing (color and weight), and use a sun screen with a high Sun Protection Factor (SPF) rating. Rest often and do not over exercise in any activity.
Spring, fall, and many winter days are near perfect for outdoor activities in the Big Thicket, Hiking, wildlife observing, nature study, canoeing, and picnicking all add to your enjoyment of the Big Thicket.
