Here’s How Much Water to Pack When You Go to the Beach
If you’re heading to the beach, you’ve probably packed your things (a book, some sand toys for the kids) and food (the best beach sandwich , of course). But did you forget to drink something? If you’re like most of us, you probably didn’t bring enough water with you.
Keeping hydrated in daily life is somewhat overrated: regular fluid intake is enough and we don’t need reminders to “drink water” while we sip when we’re thirsty. But when you’re heading out on a hike, a day at the beach, or any other outdoor adventure where resupply options will be limited, it’s important to make sure you pack enough.
How to calculate the required amount of water
Although there is not much scientific research on how much water our body needs when relaxing on the beach, there are calculations of how much water people need when exercising, hiking or camping, and they give us a guideline.
For “moderate” activities at “moderate” temperatures, REI recommends half a liter per person per hour. A typical beach day is hotter than “moderate” temperatures, but we don’t necessarily get a lot of exercise either. A half liter is the size of a disposable water bottle, so imagine a case of 12 for two people spending six hours on the beach. , or four people spend three hours. (Of course, refillable bottles would be more environmentally friendly. This is just an example to illustrate.)
However, on a hot day, you will need more. We lose water through sweating (plus some through breathing), so the more we sweat, the more water we need. A more generous rule of thumb is that travelers should take one full liter per hour (two disposable bottles) with them.
Which rule should be used? This is the verdict. If you’re always thirsty at the end of a day at the beach, take more than you think you’ll need with you.
Do other liquids count?
Good news: yes! While water is the easiest way to stay hydrated, other fluids matter too. Sodas, fruit drinks, juices, lemonade, and even aquatic products like popsicles and watermelon provide our body with water. This includes caffeinated drinks; they are not as dehydrating as you may have heard .
But I would exclude alcohol from the list. Alcohol does dehydrate you, and you should still alternate between water and alcoholic beverages when you drink throughout the day. Pack the recommended amount of water in addition to the beers or cocktails you plan to drink.
