A pair of troughs will bring increasing cloud and rain across Fiji, with a moist northerly wind flow developing from later today and showers and isolated thunderstorms spreading from the west. Afternoon and evening thunderstorms are likely to produce heavy falls in places, and some low-lying areas should be prepared for the chance of flash flooding.
Issued from the National Weather Forecasting Centre, Nadi at 3:30pm on Sunday 19 April 2026: through to midnight tomorrow most areas can expect cloudy periods with showers and isolated thunderstorms. Rain is forecast to develop from the west and spread across the group from later today. Viti Levu and Vanua Levu are highlighted for afternoon or evening thunderstorms with heavy falls that could be locally intense. Winds are moderate northeasterly, turning northerly later today, and seas will be moderate to rough.
The outlook for Tuesday is for occasional rain and isolated thunderstorms with heavy falls still possible across most places before rain gradually clears from the west later in the day. Northerly winds will freshen, then gradually shift to the southwest later in the day. Seas are expected to remain moderate to rough. Localised heavy falls may lead to flash flooding of low-lying and flood-prone areas during the period.
Most centers — including Navua, Suva and Nausori; Nadi, Lautoka and Ba; Sigatoka and the Coral Coast; Yasawa and Mamanuca; Tavua and Rakiraki; Labasa, Savusavu and Nabouwalu; Taveuni; the Lau and Lomaiviti groups; and Kadavu — should prepare for cloudy periods with showers and the possibility of afternoon or evening thunderstorms and heavy falls. Daytime maximums are generally around 30–32°C with nighttime minimums near 23°C as noted for each locality in the bulletin.
Rotuma remains under an easterly wind flow and is expected to be fine apart from brief showers, with moderate easterly winds and moderate seas. Minimum temperatures are around 24–25°C and daytime highs near 31–32°C.
