New Zealanders can now check their phone to see when they need to protect their skin from the sun. The Health Promotion Agency (HPA) has worked with MetService and NIWA to produce a range of ways the sun protection information can be easily accessed by the public. In this mix is the inclusion of the Sun Protection Alert on MetService's Towns and Cities smartphone weather apps.

If you look back to the Towns & Cities forecast tabs or the Rural forecasts, you will notice that at the bottom of the 10 day forecasts is this phrase: “Forecasts and temperatures for days 1-5 are produced by MetService meteorologists. Forecasts and temperatures for days 6-10 are automatically generated by MetService's computer weather modelling system.”

New Zealand is great for outdoor sports. Sometimes the weather is too. With summer approaching and long weekends on the calendar, the time is ripe for packing cars and heading off into the great outdoors. But how do you know if the weather is going to be any good when you’re planning a trip, particularly to places ‘off the beaten track’? This blog post is about how you can get a better idea of the weather in areas not covered by regular forecasts - the types of areas frequented by rock climbers, mountain bikers, kayakers etc.

It can be tricky here in New Zealand to fit all the weather for a day in just a few short sentences. Here are some phrases that you will often find in our forecasts and what they mean.

Wet Weather

Written by John Law, Meteorologist

Sitting out in the middle of the ocean, New Zealand is vulnerable to extremes of weather from all directions; from the remains of tropical systems barrelling in from the north, to cold winter southerlies bringing a blanket of snow.

As New Zealand’s designated national meteorological service to the World Meteorological Organisation (WMO), it is MetService's responsibility to provide clear, concise and timely warnings of severe weather that is likely to affect New Zealand.

When recruiting and training people to become meteorologists, MetService requires that trainees hold a university science degree in maths and physics. Why maths and physics? First and foremost, meteorology is a science, and we need people in our National Forecast Centre who are capable of applying the scientific thinking that they’ve developed at university to understand the state of the atmosphere. Let’s look at specific examples of why maths and physics are important to meteorology.  

The physics of fog

June 21st is the Northern Solstice and marks the shortest day here in the Southern Hemisphere.  On the 21st the sunrise is around 7:48am and sunset 5:00pm in Wellington, giving just over 9 hours of potential sunshine for the capital. The timing of sunrise and sunset varies from location to location, sunrise in Gisborne being almost an hour earlier than in Invercargill.  You can find the sunrise and sunset times on the forecast pages at www.metservice.com, just underneath the towns and cities forecasts.
