I live a five-ish minute walk from a beach. May to September dogs are baned, so it a 2 hour walk to the dog allowed part. But there is a promenade to walk along. So every day mirni g and evening I get to see the sea and the way it changes. In winter us a bit difficult especially if storms roll in, or when it's snowing so you got to have appropriate boots and waterproofs. On windy days all year around you get sandblasted, which is a bit gritty. Also you've got to brush the sand out if the dogs coats. Walking on dry sand can be a bit hard going on the ankles, my preference is right on the waterline where the wet sand is firm but you've got to contend every now and then with waves washing over you. Also sand in your footware is not nice. Occasionally I'll go barefoot
If you've got a water dog, then you've got to wash the salt out of their coats, mine hate water they look at the seafoam and then run away from the ebb and flow.
Even on really hot days there is enough of a cool breeze coming off the sea to keep the dogs cool. But not in the middle of the day, then you've got to watch out incase the dogs overheat.
After doing it daily for two years, can I recommend it? Will it live up to your expectations? Doubt it. It becomes a chore, in winter you've got to be careful of the sea state, in summer there are people who moan about dogs on a beach and depending on what they are wearing something's you can't unsee. Best times to do it? sunrise and sunset, in winter that's a pita, in sumner, you get next to no sleep. Mid spring and mid autumn are fairly ok as long as the weather is fair.
You do get to see some people behaving like absolute idiots on a beach, which can be amusing or irritating depending on what they are doing. Sunrise pissheads loaded up on gear after an all night party trying to play with the dogs is annoying (surprisingly frequent this time if year at the weekends), other dog walkers with off lead aggressive dogs is annoying. The gods of exercise doing their workout in the sand can be amusing as well as the sunrise worshipers. The Instagramers trying to lifestyle and pose are somewhere in between.
Oddly given I have a very consistent routine for walking the dogs, I really see the same people. At the weekend there are the once a week dog walkers who drive to the beach and let them loose.
Would I recommend it? Not sure, it really does depend on your commitments. If I didn't have an obligation to walk the dogs, even living as close as I do I don't think I'd be going there daily or even weekly. Did I move close to a beach to walk my dogs no. Did I get dogs to go to the beach daily, no. In hindsight would I have purposefully got dogs and moved to near a beach god no.
