I don’t have live access to weather feeds right now, but here’s a quick update based on recent typical conditions for Paris around late May: it’s commonly hot and sunny during the day, with temperatures often in the high 20s Celsius (near 30°C) and cooling at night.
If you’d like, I can guide you on how to get the exact current temperature for Paris right now from reliable sources, or I can fetch a short, up-to-the-minute summary if you enable a web lookup.
