Spring is one of the busier times to visit Tulsa, and temperatures become noticeably warmer from March into May. It is generally comfortable for driving Route 66, stopping for photos and walking around different parts of the city. Rain and thunderstorms become more frequent as the season progresses, with May being Tulsa’s wettest month on average. Severe weather is possible too, so checking the forecast is useful if you are planning a full day on the road.
Summer in Tulsa is hot and often humid, with July and August regularly reaching the low-to-mid 30s Celsius during the afternoon. Route 66 remains active with road trips and local events, but outdoor stops are more comfortable earlier in the morning or later in the day. Thunderstorms still occur during summer, although rainfall becomes less frequent after June. Air-conditioned restaurants and indoor stops make it easy to break up longer stretches of sightseeing.
Autumn becomes much more comfortable once Tulsa’s summer heat starts easing. September can still be warm, while October usually brings milder afternoons and cooler evenings that work well for exploring Route 66. Rain is still possible, but there are plenty of clear days for driving and outdoor stops. Temperatures drop more quickly in November, particularly after dark, so layers become useful later in the season. Snow is uncommon this early, although occasional November snowfall does happen.
Winter is quieter along Tulsa’s Route 66 stretch, with cold mornings, shorter days and occasional snow or ice. Daytime temperatures often remain above freezing, but nights can become much colder, particularly in January. Tulsa averages relatively little snow compared with northern Route 66 cities, though winter storms can still affect driving for short periods. Most of the city remains active throughout the season, so restaurants and indoor stops are useful when the weather is too cold for extended sightseeing.
