Instructions
The Portsea Pier weather forecast summary has general weather at the top, and more specific weather types underneath. Click on the tabs at the top of the page for an indepth view of each of our weather types, with interactive graphs and detailed statistics.
The Data
WillyWeather sources Portsea Pier weather forecast data from the Bureau of Meteorology (BoM) and the National Oceanic and Atmospheric Administration (NOAA). Other weather data is also sourced from the BoM, the NOAA, and the European Centre for Medium-range Weather Forecasts (ECMWF). To find out more specific information on our data sources, please refer to the individual weather type pages by clicking on the tabs at the top of the Portsea Pier weather forecast page, then to the relevant help buttons associated with each graph.

Portsea Pier Radar, Satellite and Synoptic Charts:
How to best use our controls
You can click on any part of the timeline to pause it, and if you hold down the mouse button as you click, then you can drag the position box along the timeline at any speed you wish.
Radar
Radar maps show the actual rain that has fallen at a particular time, depicted by coloured dots. The colour of the dots gives an indication as to how heavy the rain is falling. WillyWeather loops over these images up to the current time (usually one image every 10 mins), to give users an idea as to when the rain will reach a given point on the map.
All radar information is provided by the Bureau of Meteorology (BoM).
Melbourne is the default radar that covers Portsea Pier, which is 51.9 km's away. If the radar is not functioning for whatever reason, the closest functioning radar that covers Portsea Pier will be displayed, otherwise you will see a list of the nearest radars available.
Satellite
Satellite maps provide an excellent view of clouds in the sky, and also give an idea of wind speed. By viewing satellite images with synoptic charts (see below) you can see how the pressure systems and fronts are behaving, and the exact cloud cover that moves with them.
Satellite images are originally processed by the Bureau of Meteorology (BoM) from the geostationary satellite MTSAT-1R operated by the Japan Meteorological Agency
Synoptic
The most important feature of a Synoptic chart are the fine black lines called isobars. Isobars connect points that share the same air pressure. The distance of the isobars gives a good indication of wind strength, the closer the isobars are together the stronger the winds will be.
A high pressure system usually brings fine weather, and a low pressure system usually brings unsettled weather with more clouds and a greater chance of rain/storms.
Fronts occur where two masses of air collide with one another, and usually bring an increase in cloud cover. Warm fronts bring warmer temperatures and sometimes gradual rainfall. Cold fronts bring colder temperatures and usually heavier rain. Occluded fronts form when a cold front overtakes a warm front, and usually brings dryer air. Stationary fronts are characterised by continuous rainy periods that linger for extended periods of time in one area and move in waves. Warm, Cold and Occluded fronts travel in the direction of the arrows, and the numbers next to the black arrows show their speed in knots.
Synoptic images are provided by the Bureau of Meteorology (BoM).
