Flights to the U.S. are full these days, with those trying to maximize time with their near and dear. The weather is fine by U.S. standards, but as a visitor, you must know whether weather will affect you, if the trip is to be memorable for the right reasons. First and foremost, visitors insurance is not merely a luxury, it is almost a necessity. Medical care is expensive in the U.S., and it is best to be safe than sorry.
Second, keep in mind the weather of your destination. Pack appropriate clothing. Check the average temperature at the destination during the time of the year that you plan to visit. If you ever fall ill because of weather-related issues, you will be glad of that visitor health insurance.
Where possible, check whether your host has planned trips to places outside your primary destination. If so, make sure that you have appropriate clothing when traveling too. If you have any allergies or health problems related to higher altitudes, let your host know. Remember that being over-clothed can also become a problem.
If, after all precautions, you find yourself under the weather, let your host know immediately. Timely treatment is always better than delayed treatment. Also remember to give your host a copy of your visitor health insurance information/card upon arrival, or at the very least, provide information about the insurance.
