Best: Mar-Apr, Oct-Nov · Great: May
Rain is a non-factor here almost every month — the real story of the year is temperature, swinging from December's cooler stretch to July's peak heat. In March, expect highs around 20°C with rain on roughly 3 days of the month.
The Strip itself is the main draw for most visitors, but Red Rock Canyon and Valley of Fire State Park offer dramatic desert scenery within an hour's drive, and the Hoover Dam and Lake Mead are a classic half-day trip. Summer heat (regularly 40°C+) makes outdoor activities genuinely risky in the middle of the day — spring and fall are far more comfortable for anything beyond the casino floor.
Las Vegas has become a genuine culinary destination in its own right, with celebrity-chef restaurants concentrated on the Strip alongside classic all-you-can-eat buffets.
