MetService NZ @metservice.com · 4hGood morning Aotearoa!☀️☁️ These are your minimum temperatures since midnight! It's been a cooler night for those in the North Island, with frosty temps inland. 🧊 It's a warmer story in the South Island, as a blanket of high cloud has kept those frosts away. 🌡️ For your forecast, metservice.com 021

MetService NZ @metservice.com · 20hThis idea is still incredibly useful today. Take today’s setup, as shown above. A front is moving across the Tasman Sea, giving us a feature to watch as it tracks east towards us. By following its movement upstream, you can start building an idea of what may be heading our way before it arrives. 131
MetService NZ @metservice.com · 20hBefore the weather models we use today were created, forecasters often relied on observations from upstream locations. They would watch what was happening across Australia and the Tasman Sea to identify approaching fronts, lows and other features that could later affect New Zealand. 202
MetService NZ @metservice.com · 20h🌦️ Upstream forecasting in New Zealand New Zealand sits in a predominantly westerly flow (i.e. from the west), which means one of the best places to look when forecasting our weather is to the west. 161
MetService NZ @metservice.com · 29/09/2026The leaves on a tree are hanging in that warmer air, so unless you live somewhere that regularly gets severe frosts, those leaves are not going to freeze. Photo taken by one of our Meteorologists 041
MetService NZ @metservice.com · 29/09/2026At night, winds often die down, so within the first 10 metres or so off the ground, air naturally forms layers where the coldest air is touching the ground, and temperatures gradually increases as you reach higher. 131
MetService NZ @metservice.com · 29/09/2026Why does grass frost but not trees? 🤔 Have you ever opened your fridge or freezer and felt cold air brush by your feet? As air cools, it shrinks and becomes denser. If left undisturbed, cold air will flow towards the lowest place it can find, just like water. 1111
MetService NZ @metservice.com · 29/09/2026Ata mārie! 🌡️ This graphic shows observed temperatures from midday yesterday through to 7am today. Blenheim and Masterton saw the biggest temperature drops, falling 16°C. Invercargill was the most stable, cooling by just 2°C. ❄️ How cold did it get where you are this morning? 021
MetService NZ @metservice.com · 29/09/2026🎢 The east coast of the South Island is instore for a changeable week of temperatures. 🌡️ Highs will rise, with most places along the coast forecast to reach over 20 degrees on Thursday and Friday. 📉 A cold front moves up the country on Saturday, causing highs to plummet to around 14 degrees. 051
MetService NZ @metservice.com · 29/09/2026From the ground, you may experience periods of gloomy, overcast conditions as a cloud band passes overhead, followed by stretches of clear blue sky before the next band arrives. 021
MetService NZ @metservice.com · 29/09/2026As the wave dips back down, the cloud dries up revealing blue skies. Ultimately resulting in the stripey patterns you can see from the satellite imagery. 111
MetService NZ @metservice.com · 29/09/2026This traps the airflow into a repeating up-and-down motion. The atmosphere is full of waves, which we can’t normally see. This is what makes wave clouds so interesting, as we can see the peaks of the wave as that is where the cloud forms. 111
MetService NZ @metservice.com · 29/09/2026This causes the air to take on the shape of a wave, like what you would see on the water's surface if you dropped a stone in a pool. A layer of more stable air above acts like a lid, preventing the wave from moving higher, while the mountains or terrain stop it from sinking lower. 111
MetService NZ @metservice.com · 29/09/2026Wave clouds are formed when air is forced to flow over a mountain range or other elevated terrain and then forced back down by the atmosphere above it. 194
MetService NZ @metservice.com · 28/09/2026Cold temperatures are doubly necessary as the colder air gets, the less moisture it can hold, so the cold both extracts the moisture out of the air and freezes it. Image taken from Nelson Lakes by N. Wotherspoon 030
MetService NZ @metservice.com · 28/09/2026Ata mārie! It’s a chilly start to the day across the country with a few areas of frost, but how do frosts develop? Frosts form through moisture being squeezed out of the atmosphere onto objects near the ground, and then that moisture subsequently freezes. 1101
MetService NZ @metservice.com · 28/09/2026It's the perfect week for school holiday fun in the sun, as showers clear out and temperatures creep up into the low twenties along the east coast by Friday 🏜️ Our pick of the week for most folks is Wednesday, but check out the full forecast to decide for yourself: www.metservice.com/towns-cities 071
