If you're vacationing abroad right now, you might face these new rules

With lockdowns lifted, this summer's beaches will be different than ever: People need to be prepared to sunbathe behind a plexiglass screen or in a marked safe area - and book a spot in advance.

In Portugal, there is an app that tells you which beaches are safe, while in Los Angeles you must wear a mask even when sunbathing.

Police drones will monitor Florida beaches to enforce social distancing.

This summer, people won't be able to have so much fun in the sun. As lockdowns are lifted, local governments are implementing a series of measures on beaches to keep people safe.

So, from drones that ensure people keep social distancing to quarantine safe zones, your next trip might look like this.

1. Sunbathe behind the screen

Social distancing screens are moving from shops and restaurants to beaches. Perissa Beach is popular on the Greek island of Santorini, where plexiglass screens are installed on sun loungers.

Lifeguards in the Italian resort of Rimini have rejected a proposal to build clear plastic "boxes" to isolate sunbathers. Meanwhile, the small town of Porto Cesareo in Puglia has placed parasols on the beach at 1.5-meter intervals to ensure social distancing.

There are many ways to ensure social distancing. The beaches of Benidorm in Spain and Grande Motte in southern France are also divided into different sections to help sunbathers maintain a two-meter distance.

2. Is the beach full? Check out this app

Police have stepped in to relieve the pressure of overcrowding on beaches in the UK and Spain in recent days. This shows how eager citizens are to go to the sea during the lockdown. Some tourists said they didn't realize how busy the beach was until they got there.

Portugal has devised a technological solution: an app that uses cellphone data and information from seaside businesses to measure the number of tourists on the beach. The program alerts potential visitors that the beach is full before they set off.

Portuguese Prime Minister Antonio Costa told Reuters the app was meant to help people be held accountable and police would not monitor the number of visitors to the beach. "The beach is supposed to be a place to relax, and we have to check ourselves," Costa said.

When it comes to sunbathing, few people worry about their face. You need to take off your sunglasses, but that's about it. However, mandatory mask-wearing this year could present some interesting tanning challenges.

Los Angeles Mayor Eric Garcetti has issued an order requiring all visitors to Los Angeles County beaches to wear masks when not in the water.

The Spanish resort of Benidorm has distributed free masks to all its citizens; tourists and locals alike will have to wear masks on the beach to designated sunbathing spots. Once they are in the safe space, they can remove it.

4. Reservation only

Bournemouth's beaches on England's south coast were overwhelmed during a recent heatwave, and to prevent that from happening, some beaches were only accepting tourists who had reserved a spot on the beach.

In Canet d'en Berenguer on Spain's Mediterranean coast and north of Valencia, sunbathers must use a downloaded app to book one of 5,000 daily beach spots. Each visitor will be given two square meters of sand, separated by a plastic net.

On Spain's Atlantic coast, the resort town of Sanxenxo is allocating places on the beach on a "first come, first served" basis. In the UK, any visitor to West Wittering Beach in Sussex must use a popular parking app to book one of the limited spaces.

5. Drones to keep people socially distanced

On Daytona Beach, Florida, visitors need to maintain a certain distance, otherwise there will be a sound in the sky reminding you to stay away from people near you. Authorities in the city are using aerial drones to enforce social distancing on beaches and local parks.

Drones operated by local police will patrol the beach to monitor the behavior of sunbathers. In addition to a loudspeaker and a regular camera, the drone is also equipped with a thermal sensor that can spot any tourists who may have contracted Covid-19.

The drone was originally designed for disaster relief. The Volusia County Emergency Department, where Daytona Beach is located, also rented a light plane and dragged a banner across the beach reminding sunbathers to stay 10 feet (3 meters) apart.
