Thessaloniki weather in May

In May 2023 (from 20.05 to 31.05) my family and I vacationed in Greece, Thessaloniki, with friends. The trip turned out to be very informative and interesting. The weather was not entirely favorable, but we were still pleased. The temperature during the daytime did not rise above +25, but in the evening it was already completely cold for us (the temperature dropped to +16). Sometimes it rained a little during the day, but this did not stop us from seeing the city in all its glory. The Aegean Sea was still cold for swimming, but it warmed up to +19. In general, it's always a pleasure to relax. We will definitely return to Greece, to Thessaloniki, but in the summer, to be sure to swim in the sea and enjoy its beauty
