The best time to visit Kobuk Valley is generally July and August. It is a national park in Alaska.
July and August tend to bring the best balance of weather, access and conditions. Around then, daytime highs average about 55°F and overnight lows near 45°F.
Snow, rain, and freezing temperatures can occur any time of the year. Always travel with good quality rain gear and warm layers. Be especially careful to stay dry. Hypothermia can set in on a windy, wet day, even when it doesn't feel that cold.
