Parts of the United States and Europe are suffering under blistering temperatures as another round of record-breaking heatwaves takes hold of the northern hemisphere. Here’s what you need to know about the current heatwaves, when they might end, and how to stay cool while traveling.
The National Weather Service (NWS) continues to issue excessive heat alerts this week, particularly in the southwest and central areas of the US, with no indication yet as to when the unrelenting triple-digit temperatures and high humidity will lessen. Additionally, the northeast region is experiencing scorching conditions, with Amtrak warning of service disruptions as the heat causes the rails and overhead wires to expand.
Countries in Western Europe are facing similar issues as the region endures its second heatwave in less than a month, which threatens glaciers in the Alps and worsens drought conditions across the continent. In southwest France, wildfires are raging as the country continues to break heat records, following the hottest June recorded in France since 1850. Towns near Bordeaux have been placed on high alert, with thousands of people evacuated this week due to wildfires engulfing an area the size of Paris in Gironde.
Elsewhere, Spain is confronted with “suffocating” temperatures and wildfires along the Portuguese border. The hottest provinces, namely Andalusia, Extremadura, and Galicia, are witnessing temperatures reaching approximately 113 degrees Fahrenheit (45 degrees Celsius). Weather forecasters project a slight easing of temperatures this week, yet increases are still anticipated in parts of France and the UK.
The frequency of heatwaves this year has been correlated with climate change, as the UK Met Office confirms that this “historic, even unprecedented” season of high temperatures will likely continue throughout the summer. Furthermore, Germany, Switzerland, Poland, and other European nations are preparing for hotter-than-average temperatures in July, with officials encouraging visitors to take necessary precautions to stay cool.
Given the surge in heat records globally amid the climate crisis, staying cool while traveling has become increasingly challenging. This is particularly true in locations lacking efficient air conditioning systems, where buildings are not designed for frequent and prolonged high temperatures. However, aside from wearing loose clothing made of natural fibers and staying hydrated, how can you ensure comfort while continuing to enjoy your adventures?
Bring a fan, a battery pack… and a mini spritz bottle
For anyone traveling, particularly on planes, my primary recommendation is to acquire a USB fan that can plug into your external battery pack. My preferred model is the Arctic Breeze Mobile — it boasts a flexible neck, and the blades are constructed to balance noise and air circulation effectively. This gadget can prove invaluable in stuffy hotel rooms.
Additionally, I recommend carrying a mini-spritz bottle to fill with water during the summer months. It’s an eco-friendly and cost-effective alternative to expensive spray cans of Evian water. A quick spritz on your face, followed by letting the fan do its job, will help provide a refreshing cool down.
If you are planning a road trip, seriously consider packing a small desk fan from home or investing in one if you will be spending extended time on the ground overseas. Hotels often have a limited supply of fans, and having one readily available in your vehicle can be a lifesaver at night.
Travel early in the day, and siesta, siesta, siesta
Regardless of whether you’re flying, taking the train, hopping on a bus, or enjoying a road trip, aim to travel early. This is slightly more complicated if you’re dealing with jet lag and need to adjust your body clock, especially when heading east. Nevertheless, mornings tend to be the coolest times for travel, which helps to minimize disruptions from high temperatures.
Additionally, an early start allows more room in your schedule to accommodate potential delays, rather than getting stuck in an uncomfortable location. Should you find yourself delayed, make the most of the situation and explore your surroundings if possible. Consider breaking the day in two with a proper siesta; retreat to your (hopefully well-cooled) hotel room for a nap, a refreshing shower, and then take full advantage of the latter part of your day. Ensuring that your body can cool off for a few hours daily is crucial.
Pick a plane with air vents
As a staunch advocate of the #WeWantAirVents movement on Twitter, I understand how challenging it can be to find planes equipped with overhead nozzles. Generally, older and smaller aircraft are more likely to have these amenities that direct cool air onto passengers, making summer travel more comfortable.
If you have a choice during the warmer months, opt for smaller planes like the Airbus A220, A320, or Boeing 737, or comfortable regional jets such as the Embraer E170, E175, E190, or E195. Although not a guarantee, these aircraft typically offer improved cooling conditions.
Pack a handkerchief… and a shirt
One of my favorite cultural aspects of Japan is the customary carrying of handkerchiefs. This practice proves incredibly beneficial for wiping sweat away, avoiding the hassle of tissues that can stick to your face. It also serves as a convenient tool for drying your hands in public restrooms or providing relief during intense heat. You might even consider dampening it and draping it over your head and neck, or chilling it in the freezer for extra comfort.
If space permits, include an extra shirt in your bag for the day. Having a dry, clean shirt available to change into can be incredibly refreshing when you are feeling sticky and uncomfortable due to the heat.
Always bring a bottle… of water
It’s widely recognized that consuming alcohol during a heatwave is inadvisable, while staying hydrated is crucial. However, due to security restrictions, large filled bottles cannot be brought through, and onboard water can be expensive. I suggest packing a large empty bottle in your carry-on luggage, so you can refill it after passing through security.
Don’t expect free water or for bottles to be widely available
In countries such as Germany, it’s surprisingly common not to receive complimentary water with meals or drinks. I recall an oppressively hot summer day in Hamburg, where I found myself at a beer bar, desperately needing a large glass of water. However, the only option was to purchase an expensive five-euro half-liter bottle.
Furthermore, even in France, it is quite rare for shops to offer fridges stocked with bottles of water compared to other countries. Therefore, do keep this in mind: fill your bottle in the morning and seek refills whenever possible throughout the day.
Pick a hotel with AC, but try and ensure it has an actual unit
Determining whether a European hotel genuinely offers air conditioning can be a tricky endeavor. Those misleadingly labeled small vents that emit warm air hardly qualify as adequate air conditioning, even though they are legally permitted to use that designation. There is often little opportunity to open the windows sufficiently to provide relief either.
The key is to examine room pictures and online reviews to confirm the presence of a genuine air conditioning unit. Make sure to verify you’re looking at the appropriate room category, as securing a comfortable space will likely make your stay more enjoyable.
A bonus recommendation is to choose a low-floor room situated on the north or east side of the hotel (in the northern hemisphere; south or east in the southern hemisphere) to maximize exposure to morning sunlight or even minimize heat altogether. Remember to draw the blackout blinds before departing for the day!
Shower multiple times a day, including at the airport
There’s a delightful sensation associated with showering in lukewarm or cool water, especially when you feel the temperature of the water gradually warming up as it cascades down your body. This method effectively cools you off.
An increasing number of airports now provide showers, even without requiring access to a lounge. In the summertime, having the chance to rehydrate and find a comfortable spot can justify the cost of lounge entry. Additionally, don’t feel obligated to dry your hair thoroughly; leaving it damp can aid in dissipating heat from your body, so feel free to wet it during the day to alleviate discomfort.
Good luck — and remember to stay cool!
