Weather situation

A high pressure system in the Bight is extending a ridge across the state's south and east while heading eastwards, moving across southeastern Australia and reaching the Tasman Sea by late today or Wednesday. Then, a series of troughs are forecast to enter the state's west and slip south later in the week through the weekend, drawing heat and moisture across the state.

Climate statistics for Sydney Airport since 1929.

Notes:

The four temperatures:
- Temperature: The ambient air temperature.
- Feels like: Based on temperature, humidity and wind chill (but not the sun), this is meant to be the temperature it feels like for an adult walking in the shade if there is no wind and at a standardised humidity level.
- Dew point: The relative humidity would be 100% (i.e., unable to hold more water vapour) if the air was cooled to this temperature. This is an absolute measure of humidity.
- Wet bulb temperature: The temperature if a wet thermometer had air moving over it (evaporative cooling), so it depends on temperature and humidity. Useful because people cool the same way.
Current observations: The little charts show the last six hours at half hour intervals. Hover over with your mouse to see details. UV index is average of last five minutes.
Radar: Click on to go to BOM radar. Pause with the button above.
UV index: This is shown as a chart for the major cities that have minute-by-minute forecasts and observations and as a table when there is only an hourly forecast.
UV index (chart): Blue line is five minute average. Shaded area indicates range of measured values. If there is a lot of variation, now measured is average of last five minutes and the range is also shown.
UV index (table): Forecast assumes a clear sky. Rows are highlighted if the forecast is for within 45 minutes of the current time.
Sunrise and sunset: Dawn and dusk are for the start and end of civil twilight (the sun is 6° below the horizon).
Recent days: Rain is the total in the 24 hours up to 9am. Minimum is in 24 hours to 9am. Maximum is in 24 hours from 9am.
Last 72 hours: Most values are the value at the time shown. Rain is the amount of rain in the previous 30 minutes from the time shown. Wind direction is shown for every two hours (all values are shown on hover).
Next 36 hours: Most values are what are expected at the time indicated, while rain forecasts are for the three hours beginning at that time. Median rain means there's a 50% chance of more rain than the given number.
Space weather: K_aus is the K-index for Australia, a number between 0 and 9 indicating the level of magnetic field disturbance. 5+ are classed as geomagnetic storms. Aurora alerts and watch notices are also shown at the top of page if potentially visible from the current location.
Climate statistics: 80% of the time the value is in the yellow area on the chart. The top 10% fall above it and bottom 10% fall below. Daily wind run is effectively the amount of wind that blows past (i.e., average speed times 24 hours). Cloud cover is measured in oktas, which ranges between 0 (completely clear sky) and 8 (completely overcast).
