Inverness in June

May through September gives you the best weather odds, though 'best' is relative in the Highlands. Expect temperatures around 15-18°C (60-65°F) and pack layers regardless of the forecast. July and August bring crowds and higher prices, but also the Edinburgh Festival effect — more events, longer daylight (sunset after 9 PM), and everything actually open. Hotel rates jump 30-40% during peak summer. My pick? Early September. Tourist numbers drop after school starts, but weather stays decent into October. Plus, you might catch autumn colors in the surrounding glens. Hotel prices drop back to reasonable levels too. Winter (November-March) means short days, unpredictable weather, and limited daylight for sightseeing. But if you're chasing Northern Lights or want cozy pub evenings, it has its charm. Just know that some Highland attractions close or run reduced hours. Avoid late October through early November — you get winter weather without winter atmosphere, and many seasonal businesses shut down for maintenance.
