Best time to visit Hawaii from Australia

Summer from June to August is peak season with the busiest beaches and highest hotel rates. Shoulder season from April to May and September to October offers good weather with fewer crowds and lower prices. The winter season from November to March brings more rain and larger surf on the North Shore of Oahu, which draws surfers for the famous Triple Crown of Surfing. Humpback whales visit Hawaiian waters from December to April. Australian school holidays from December to January coincide with Hawaii's busy winter whale-watching season.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
