The weather and temperature can both change quickly in the mountains, and that usually means it gets colder or starts to rain with little warning. This is especially true in higher elevations, where hikers are more exposed to the elements.
Below is brief primer on what to expect during each season. This is just an overview, so always check the weather forecast before heading out. It can snow in June! For more information on what to bring on your adventure, check out our What's In Your Pack? page. (Link to page)
Summer: Think warm days and cool nights, especially in higher elevations. Daytime temps can creep into the 80s in July and August, but they can also dip into the low 60s, especially when it's raining. Don't be surprised if you're swimming one day and wearing long sleeves the next! If you're heading for a summit, be aware that thunder and lightning storms can roll in fast. Avoid open summits if there's any hint of a storm.
Fall: Think cool days and chilly nights. Some people think fall is the perfect hiking weather. The daytime temperatures usually stay below 80, making for cool breezes on difficult hikes, and the foliage is simply amazing to behold. It's true that it can snow during a chilly summer night here, but that's fairly uncommon. As fall descends on the region, the chance of waking up to a white dusting increases considerably.
Winter: Think cold days and even colder nights. Winter is our longest season. Sometimes it's mild, with daytime temperatures staying in the double digits, but the mercury is more than capable of diving below zero, especially in January and February. Expect deep snow, bring plenty of extra layers, and make sure you know your abilities before setting out. Nights are particularly cold in the winter, so if you're camping be sure to consult with someone familiar with the region to make sure you're fully prepared.
Spring: Think cool days and chilly nights. Locals here joke that we go straight from winter to summer in the Adirondacks, and some years it does feel that way. As the snow melts you'll encounter muddy trails in the valleys and winter-like conditions in higher elevations, meaning you'll probably be pulling out the microspikes as you near a summit. It's important to bring extra layers this time of year, and to avoid our highest mountains to give their trails time to harden after enduring the long winter.
In the Adirondacks, most regulations are aimed at protecting our natural resources so future generations can enjoy them, too. The rules are simple and easy to follow, so please take a minute to familiarize yourself with them before planning your trip. Note: this list does not include everything.
