2009–10 South Pacific cyclone season#Severe Tropical Cyclone Rene

Ahead of the cyclone season, RSMC Nadi, TCWC Wellington, the Australian Bureau of Meteorology (BoM), the New Zealand National Institute of Water and Atmospheric Research (NIWA) and various other Pacific Meteorological services, all contributed towards the Island Climate Update tropical cyclone outlook that was released during October 2009. The outlook took into account the El Niño conditions and normal developments during a near-normal season. The outlook called for a near average number of tropical cyclones for the 2009–10 season, with eight to eleven tropical cyclones, to occur between 135°E and 120°W compared to an average of about nine. At least two of the tropical cyclones were expected to become category 3 severe tropical cyclones, while one was likely to become a category 4 severe tropical cyclone. The outlook also noted that it was likely that the first storm would develop prior to the end of December. During February 2010, a seasonal forecast update was issued which maintained the original forecast of eight to eleven named tropical cyclones.{{cite web|url=http://www.niwa.co.nz/news/tropical-cyclone-outlook-update-normal |title=Tropical cyclone outlook update: normal |publisher=The National Institute of Water and Atmospheric Research |date=February 15, 2010 |access-date=January 20, 2014 |archive-url=https://web.archive.org/web/20100524051814/http://www.niwa.co.nz/news-and-publications/news/all/tropical-cyclone-outlook-normal2 |archive-date=May 24, 2010 |url-status=live |df=mdy }} In addition to contributing towards the Island Climate Update outlooks, RSMC Nadi issued their own seasonal forecast for their area of responsibility. Within their outlook RSMC Nadi predicted that between eight and eleven tropical cyclones, would occur within the basin compared to an average of around 9. At least two of the tropical cyclones were expected to become category 3 severe tropical cyclones, while one was likely to become a category 4 severe tropical cyclone.

Both the Island Climate Update and RSMC Nadi's tropical cyclone outlooks assessed the risk of a tropical cyclone affecting a certain island or territory. Regional sea surface temperatures indicated that the Coral Sea was warmer than normal, but this was not expected to increase the risk of tropical cyclones in the western South Pacific. As a result, it was predicted that the island nations located to the west of the International Date Line, would face a near average risk of being affected by a tropical cyclone. However island nations to the east of the dateline such as Niue and Tonga, faced an increased risk of being affected by a tropical cyclone. It was also noted that cyclones could affect parts of southwest French Polynesia and the southern Cook Islands during an El Niño, while the number of ex tropical cyclones coming to within {{convert|550|km|mi|round=5|abbr=on}} of New Zealand was expected to remain about normal. Within the Island Climate Update forecast update it was reported that the Solomon Islands faced an increased risk of tropical cyclones affecting them.

The 2009–10 South Pacific cyclone season was near its climatological average, with eight tropical depressions intensifying into tropical cyclones within the South Pacific to the east of 160°E, while another system became a tropical cyclone after it had left the basin.{{Cite web |url=http://www.pacificdisasterclimatemeeting2013.net/docs/pmc/work_papers/WP_4.0_Att._2._Report_from_14RMSD_and_PMC-1_2011.pdf |title=Archived copy |access-date=January 20, 2014 |archive-url=https://web.archive.org/web/20140202101730/http://www.pacificdisasterclimatemeeting2013.net/docs/pmc/work_papers/WP_4.0_Att._2._Report_from_14RMSD_and_PMC-1_2011.pdf |archive-date=February 2, 2014 |url-status=dead |df=mdy-all }} a warm ENSO episode persisted during the season through April, peaking in late December. The El Niño event slowly decayed due to consistently negative SOI values and weak trade winds in the tropics. The active Madden–Julian oscillation phases generally occurred during periods of increased convective activity in the region, but in March, only a weak pulse traversed the region but at the same time an Equatorial Rossby wave tracked westwards and triggered Cyclones Tomas and Ului.

Tropical Cyclone Mick was the first tropical disturbance to grace the waters of the South Pacific Ocean during the season. Tropical Cyclone Mick originally developed as a Tropical Disturbance on December 3, and gradually developed before it was named Tropical Cyclone Mick late on December 12. During the next couple of days the disturbance, the system accelerated towards the southeast while gradually intensifying further before peaking on December 14, with 10-minute sustained windspeeds of 110 km/h, (65 mph) and 1-minute winds of 130 km/h, (80 mph). Later that day, Mick made landfall on Viti Levu to the northeast of Nadi and as a result of land interaction, Mick rapidly weakened and became an extratropical depression early the next day. On December 6, Tropical Disturbance 02F developed about 1000 km (620 mi) to the north of Suva, Fiji.

Late on December 3, RSMC Nadi reported that Tropical Disturbance 01F had developed out of a weak area of low pressure to the northeast of Fiji. Over the next few days the disturbance gradually developed before RSMC Nadi reported that it had intensified into a tropical depression late on December 11. During the next day the system intensified further with the JTWC starting to issue warnings declaring it as Tropical Cyclone 04P. Later that day RSMC Nadi reported that Mick had intensified into a category one tropical cyclone and named it as Mick, while it was located about 225 km, (140 mi) to the west of Rotuma. During the next day Tropical Cyclone Mick accelerated towards the southeast while gradually intensifying further, before during December 14, as Mick approached the Fijian island of Viti Levu, the cyclone developed an eye. RSMC Nadi then declared that Mick had peaked with 10 minute windspeeds of 110 km/h, (65 mph) while the JTWC reported that it had peaked with 1 minute winds of 130 km/h, (80 mph). Later that day, Mick made landfall on Viti Levu to the northeast of Nadi. As a result of land interaction, Tropical Cyclone Mick rapidly weakened and became an extratropical depression early the next day. The extratropical remnants of Tropical Cyclone Mick were tracked by RSMC Nadi and TCWC Wellington for another 2 days before they dissipated early on December 18 Just inside TCWC Wellington's area of responsibility.

At least 6 fatalities have been attributed to Mick.{{cite web |url=http://www.rnzi.com/pages/news.php?op=read&id=50984 |title=4,000 people in Fiji displaced by cyclone |date=December 16, 2009 |work=Radio New Zealand International |access-date=September 18, 2011}}
