Seasons/Climate/Recommended Clothing: In summer, the weather can be variable. Morning fog can blanket the grove and cool the air while afternoon temperatures can warm up quite nicely. Many trails lead into the upper hills of Austin Creek where temperatures can soar above 100 degrees. Layered clothing, a fully charged cell phone and plenty of water is highly recommended. Cellphone coverage is not available in all locations. In the springtime, wildflowers are prolific, temperatures are mild and the fog is less frequent. In winter, temperatures drop but remain moderate. Rain nourishes the grove and brings life to the many plants and ferns, turning the understory into a green, lush carpet. A sweater and rain jacket will allow you to enjoy the special tranquility found in the grove as water drops work their magic.
