November 2007 Dry and Calm

Tawa’s climate during November 2007 was calmer than normal, much drier than 2006 but otherwise typical for the time of year.

November 2003 started with sunny days, until showers arrived mid-month, with a downpour on the 15th. Nor’westerly conditions then brought drizzly or rainy days for most of the rest of the month.

November 2004 featured sunny, calm days until northerly conditions brought rain on the 5th, and showery weather predominated for the next week. Muggy, still conditions on the 14th featured a downpour that evening before a north-west gale brought a mix of steady rain, intermittent downpours and sunshowers the following day.

Conditions slowly eased and milder weather prevailed for several days before a gusty northerly on the 20th moved to the north-west and rose to gale force. Winds then eased, with a spell of showers on the 23rd, steady rain on the 25th, and a cold southerly with showers and hail on the 26th. The southerly slowly eased, and the 29th was a drizzly foggy day following a brief westerly gale around dawn.

November 2005 started with cool, still conditions, with a gusty northerly rising for a few hours on the 3rd and 5th. Calm cool conditions returned until the 16th when a gusty nor’easter blew for a few hours late in the day. A gusty northerly arose on the 19th and blew steadily until abruptly changing to the south early on the morning of the 22nd when a brief spell of showers arrived. The wind dropped but still blew from the south, bringing cool, drizzly conditions until the 28th when it increased in force for a few hours before dropping completely.

November 2006 also started with cool calm conditions, but these were soon replaced by a gusty northerly which arrived on the 4th and increased in strength on the 5th, bringing showers. The wind eased but left gloomy days of showers, low cloud and fog on the 6th and 7th. The 8th was showery, and a cold southerly brought showers, hail and intermittent downpours of rain on the 9th.

The wind changed to the north on the 11th, then turned to the north-west and rose to gale force during the evening, bringing drizzle and low cloud the next day. The wind dropped for most of the 13th, but returned as a gale northerly on the morning of the 14th, rising to severe gale force during the afternoon. Gusts up to 150 km/h were recorded on the Rimutaka Hill Road, closing it to most traffic while gusts to 125 km/h were recorded at Mt Kaukau at about 4 p.m. The Mount Victoria Tunnel was closed by a fallen tree and, as evening fell, wind gusts peaked at 150 km/h at Mt Kaukau and 120 km/h in downtown Wellington. Hanmer Springs in the northern South Island bore the brunt of the storm, where a man was killed by a falling tree, many trees were uprooted and house rooves were lifted.

Back in Tawa the wind blew strongly through the night, easing just before dawn but leaving showers and misty low cloud. The respite was short-lived with a short period of sun on the afternoon of the 15th being replaced with showers and a strong northerly on the 16th, 17th and 18th. 21 mm of rain fell on the 17th, and a downpour contributed most of the 18 mm which fell on the 18th. As the wind abruptly dropped just after midnight on the 18th, some locals wondered “What next?” The magnitude 5.5 earthquake in the Marlborough Sounds at 3:38 a.m. on the 19th answered that question by eagerly rattling doors and windows as it rumbled through in the unexpectedly quiet conditions.

The still conditions continued through the 20th and 21st, with periods of drizzle, but the northerly returned on the 22nd, rising to gale force on the 23rd and 24th. The wind eased on the 25th but returned to gale force on the 26th, bringing showers. A brief thunderstorm on the evening of the 27th, cast hail about before easing back to showers. Calm returned until the 30th, when a northerly gale returned with steady rain to usher in a dismal start to December.

November 2007 began with 4 days of low cloud and showers. Things improved dramatically on the 5th and sunny days with little or no wind predominated until the 12th when a northerly wind began rising. Strong gusts brought showers on the 13th, and an impressive thunderstorm at 10 p.m. was followed by a 22 mm downpour early the next morning as the wind changed to the south and rose to gale force.

Having been spoilt with slowly rising temperatures, Tawa residents noticed the chilling effect of the southerly gale which slowly eased late on the 14th. Steady rain with banks of fog set in on the evening of the 15th and the morning of the 16th, giving way to calmer sunny days. The pleasant conditions persisted until a strong northerly arrived on the 21st bringing cloudy windy days until 24th when the sun broke through again. Sunny, dry conditions then prevailed until the month’s end with brief periods of gusty northerlies on the 25th and 26th and southerlies on the 28th.
