Weather
Fiji is a tropical country with two seasons: wet (rainy) and dry. January is right in the middle of the wet season, also sometimes called Fiji's summer. You should expect some rain daily, but this might vary between a short, sharp shower and torrential rain all day. Being "summer," January is also hot and humid in Fiji; the sun can be scorching when it's not raining. Although temperatures are fairly uniform year-round, expect high temperatures of up to 86°F (30°C).
As well as "normal" wet weather in January, there's the threat from cyclones, which bring heavy rains and wind and can be very destructive. Luckily, there's usually plenty of warning when a cyclone is on its way to Fiji. Buy flexible flights and accommodation if possible, and be prepared to change your plans with a few days' notice if you end up in the path of an approaching cyclone.
Crowds & Costs
Although January is right in the middle of Fiji's wet season, which is generally the low season, Christmas and New Year are one of the busiest times in Fiji, with the highest prices. This peak within the broader low season extends into early January when travelers from North America and Europe, but particularly Australia and New Zealand, are still on vacation.
By mid-to-late January, this rush is over. Prices drop, as does the number of visitors, and you're most likely to get a bargain on accommodation and flights in late January and February.

Where to Go
Although you shouldn't be put off a beach vacation in Fiji in the rainy season, it's a good idea to choose your location wisely. In January, head to a resort around Nadi, on the west coast of Viti Levu. This is the drier side of the island, and many resorts cluster here precisely for this reason, so you won't be short of options. For an exceptionally luxurious experience, head to Denarau Island (not technically an island), west of Nadi.
Another advantage of staying in or around Nadi is that this is where boat transfers to the Mamanuca and Yasawa islands depart from. When visiting these tiny islands, consider staying in a humble local homestay rather than a large resort. Learn about everyday life in Fiji and get to know the local people in a way that's impossible from a regular hotel. Living quarters are usually basic but clean and comfortable, and activities typically include a village tour.
What to Do
Surfing can be done in Fiji year-round. Aside from surfers not being bothered by the rain when they're getting wet anyway, tropical storms around northeastern Australia bring excellent waves and shorter swells to Fiji. Plus, as this is the low season for tourism, you won't have to compete with other surfers for space. The Mamanuca Islands are especially famous for their surfing. The waves here are primarily suited to intermediate and advanced surfers, but there are some beginner-friendly spots too.
Another fun adventure ideal in January is joining a half or full-day safari tour of the Sigatoka River on Viti Levu's southwest coast. Enjoy the refreshing breeze from a jet boat ride up the river into the island's jungle-covered interior. Visit a local village and enjoy a cultural performance.
Events in January
Fiji Coral Coast Sevens Tournament, Lawaqa Park, Sigatoka. Whether or not you're already a rugby fan, attending this rugby tournament in late January is a good way to have some fun, meet local people, and learn more about a sport that's a way of life for many Fijians.
