How do I mark where my group is sitting on a beach?

Use something tall and visible from a distance - a bright umbrella, a flag, or a windbreak in an unusual colour. Then note the nearest fixed reference on the promenade, such as a lifeguard tower number or a named beach bar, because your visual marker disappears the moment you are at sea level in the water.

What is the best way to describe a spot on a beach?

Use the fixed infrastructure, not the sand. Lifeguard tower numbers, groyne or breakwater numbers, beach access gate numbers, and named bars are all countable and signposted. "Twenty metres left of tower 4" is findable; "near the middle" is not.

How do I keep my phone safe at the beach and still stay reachable?

Nominate one phone as the group phone and keep it with whoever is not swimming, in a dry bag. Everyone else can leave theirs in a bag. One reachable phone with an agreed marker beats six phones buried under towels.

How to find your group on a crowded beach

Beaches are deceptively difficult. There are no walls, no corridors, and no signs, so there is nothing to describe. Every stretch of sand looks like every other stretch of sand, especially from the water, where your eyeline is about thirty centimetres above sea level and every umbrella on the beach looks the same.

Then someone goes for a swim, drifts two hundred metres down the coast with the current without noticing, and comes out somewhere completely unfamiliar.

Use the infrastructure, not the sand

Beaches do have a coordinate system. It is just on the edges rather than in the middle.

Lifeguard towers are numbered. This is the single best reference on any managed beach.
Groynes and breakwaters - those wooden or stone barriers running into the sea - are countable and fixed.
Access gates and steps from the promenade are usually numbered or named.
Named beach bars, kiosks, and hotels behind the beach are visible from the water and on every map.

“We’re between tower 4 and tower 5, up near the steps” is a location. “We’re on the beach near the middle bit” is not.

Plant a flag, literally

From sea level, or from a hundred metres down a packed beach, you cannot see people. You can see tall objects.

Bring something vertical and ugly: a brightly coloured umbrella, a flag on a pole, a windbreak in a colour nobody else has chosen. Boring beige is invisible; neon orange is a landmark. Take a photo of your setup and the view behind it when you arrive, so latecomers get a picture rather than a description.

Before anyone gets in the water

Tell someone you are going in, and roughly how long. Not for drama - so that if you come out further along, someone knows to look rather than assuming you are at the kiosk.

Look behind you before you swim out. Pick your reference on land - the tower number, the hotel with the blue roof - and check it again while you are in the water. Longshore drift moves people along a coast steadily and invisibly. Coming out two hundred metres from where you went in is completely normal, and it is why people “lose” their group.

Swim between the flags where they exist, and follow the lifeguards’ instructions. That is a safety matter first and a findability matter second.

Phones and water do not mix, so plan around it

The beach is the one meetup where the expected answer - “just text them” - is often unavailable. Phones are in bags, under towels, or deliberately left in the car.

The practical fix is one nominated group phone, held by whoever is on the sand at any given time, ideally in a dry bag. Everyone knows which phone is live. Latecomers message that one. It removes the situation where six people each assume someone else is watching the chat.

Set a check-in time too: “everyone back at the umbrella at 3pm for food.” A time-based regroup needs no signal and no battery.

For latecomers and big groups

This is where a shared map genuinely helps, and it helps at the edges rather than in the middle.

Someone arriving two hours late on a two-kilometre beach has a real search problem. Sending them a pin drops the search radius from “the whole beach” to “walk twenty metres”. Same for the group that splits between the water, the bar, and the car park.

Where Nearby fits

We build Nearby, so read this accordingly.

The beach fit is specific: the pin, and the no-install part. You drop a pin exactly where the umbrella is planted and share one link in the group chat. Whoever is coming later opens that link - in the app if they have it, or straight in their phone’s browser if they do not - and walks to the pin. They do not need an account or an app store, which matters when someone is arriving on a beach in a foreign country on patchy data.

Where it does not help: nobody is taking a phone into the sea, and a map will not find a person who is swimming. That part is solved by the tall umbrella, the tower number, and telling someone before you go in.

It also expires on its own, which suits a day out - nothing keeps running after you have driven home.

The beach checklist

Pick your spot by tower, groyne, or gate number, and say the number out loud.
Plant something tall and garish. Photograph it.
Nominate one group phone and put it in a dry bag.
Before swimming, tell someone and fix a landmark on shore.
Agree one regroup time so the day does not need coordinating.

Nearby is free on Google Play, and latecomers can join your map from any browser.
