Newfoundland in July

June through September is prime time, but each month serves up something different. June brings the first icebergs and wildflowers exploding across the landscape. The weather's unpredictable – pack for all four seasons in one day. July and August offer the warmest temperatures (15-20°C), peak whale watching, and festival season in St. John's. But also crowds and higher prices. September might be the sweet spot: fewer tourists, spectacular fall colors, whales still around, and you might catch the Northern Lights. The shoulder seasons have their charms too. May offers cheaper accommodations and the first puffins arriving at Witless Bay, though many tourist services aren't fully operational. October through April? Brutal weather but incredible Northern Lights, and you'll have the place mostly to yourself. Just know that many coastal accommodations close, and you're gambling with flight cancellations.
