June ushers in coastal and cultural events in southern New England while marking the transition to hotter weather in Tucson. In the Providence area, select WaterFire evenings, outdoor concerts, farmers markets, and waterfront events can increase local hotel and car rental demand. Newport begins its summer season with sailing regattas and historic house tours, and Cape Cod attractions open up for the season. In Tucson, June signals the approach of monsoon season—while there are fewer major festivals compared with spring, local markets and outdoor evening events continue. If your itinerary includes festival weekends, book flights, hotels, and rental cars well in advance.
