Autumn from September to October is warm at 12 to 20 degrees with the vineyards harvesting and the Prague autumn cultural season. Summer from June to August is the most crowded period with temperatures of 20 to 28 degrees and the largest tourist numbers on Charles Bridge and in Old Town Square. Winter from November to March is cold at minus 5 to 5 degrees but the Prague Christmas markets in December are among the best in Europe.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
