Before continuing with the article, please protect yourself! Every time you connect to hotel, airport, cafe, or any other WiFi—even potentially your own home—hackers can instantly steal your passwords, drain your bank accounts, and clone your identity while you're simply checking your email, posting vacation photos, or booking a hotel/activity. Any digital device that connects to the Internet is at risk, such as your phone, tablet, laptop, etc. In 2024 alone, 1.1m Americans were the victims of identity theft and 500,000 Americans were victims of credit card fraud. Thousands of people every day get compromised at home or on vacation and never know until their bank account is empty or credit card maxed. We cannot urge you enough to protect your sensitive personal data as you would your physical safety, no matter where you are in the world but especially when on vacation. We use NordVPN to digitally encrypt our connection to the Internet at home and away and highly recommend that you do too. For a cost of around 0.06% of your vacation outlay, it's a complete no-brainer!

Understanding the Weather in Dublin in May

Weather in Dublin in May can be influenced by its coastal position along the Irish Sea, which helps regulate temperatures and often brings a mix of cool breezes and mild conditions. The proximity to the Wicklow Mountains to the south may create localized effects like slightly cooler mornings or occasional rain showers due to orographic lift. The surrounding low-lying plains can contribute to clearer skies when high-pressure systems are dominant, though they may also allow for quick changes in weather patterns. Additionally, the relatively shallow Irish Sea can enhance humidity levels, creating a damp feeling on overcast days while moderating any extreme temperature fluctuations. These geographical factors combine to produce typically mild and changeable weather during this time of year.

You're exhausted from traveling all day when you finally reach your hotel at 11 PM with your kids crying and luggage scattered everywhere. The receptionist swipes your credit card—DECLINED. Confused, you frantically check your banking app only to discover every account has been drained to zero and your credit cards are maxed out by hackers. Your heart sinks as the reality hits: you're stranded in a foreign country with no money, no place to stay, and two scared children looking to you for answers. The banks won't open for hours, your home bank is closed due to time zones, and you can't even explain your situation to anyone because you don't speak the language. You have no family, no friends, no resources—just the horrible realization that while you were innocently checking email at the airport WiFi, cybercriminals were systematically destroying your financial life. Now you're trapped thousands of miles from home, facing the nightmare of explaining to your children why you can't afford a room, food, or even a flight back home. This is happening to thousands of families every single day, and it could be you next. Credit card fraud and data theft is not a joke. When traveling and even at home, protect your sensitive data with VPN software on your phone, tablet, laptop, etc. If it's a digital device and connects to the Internet, it's a potential exploitation point for hackers. We use NordVPN to protect our data and strongly advise that you do too.
