Big waves, Aloha and broken boards are staple fare in surfing's hometown. Whilst more chilled breaks do exist away from the Oahu's legendary North Shore it is the shallow powerful reefbreaks, big wave spots and points which pull in thousands of surfers, if only to watch. Throughout the year the islands receive swell, peaking in the primary October to March winter season when powerful north-west swell hammers the coastline. All the Hawaiian islands receive excellent swell and by no means is surfing constricted to just the well known spots. Southerly and easterly swells dominate during the summer months lighting up the other sides of the island chain. Consistent trade winds blow predominantly from the east apart from when the less frequent southerly Kona wind blows. These volcanic mountains in the sea have no continental shelf to impede the waves here which grace the cover of so many magazines. Surfing was first documented here in 1779 but in all likelihood the Polynesian people had been surfing here since 400AD. Water temperatures are a warm 25 to 27ºC or 77 to 81ºF year-round.
