Best time to visit Hawaii
Average temperatures vary little between summer and winter in Hawaii, but rainfall can be heavier in the winter between November to March, though is often very localised. The average daytime highs range from 27-32°C, while average lows are 18-24°C. For the best all-round weather, aim to visit Hawaii in the dry summer season from April to October, which is ideal for hiking and snorkelling.
However, the wet, winter season is the best time for whale watching, with migratory humpbacks arriving in the coastal waters during late November and December often staying until May.
July and August are peak months in summer and as you’d expect, Hawaii is busy (and more expensive) during Christmas and the New Year. With the school holidays over, September is an excellent month to visit with fewer crowds and idyllic sea conditions for snorkelling.
