Weather Data Accuracy
The weather data displayed on the website comes wirelessly from outside sensors before being processed by Sanday Soft's Cumulus software. The software bases weather forecasts upon current pressure readings. Usually pressure less than 1010hPa brings unsettled weather. Greater than 1010hPa brings settled weather. From 1020hPa, weather is generally sunny and calm. 1030hPa or more can bring changeable weather from fine sunny days to thunder storms.

Cumulus also bases the forecast upon how quickly the pressure is rising or falling. Static pressure usually brings settled weather. Rapidly falling or rising pressure usually brings bad, uneasy weather.

Occasionally some figures may not be displayed accurately on the site. This is usually caused by a transmission error. We try to fix these errors as quickly as we can however sometimes the days extremes may be compromised until we can fix this problem.

Our help page has more information about forecasting, units of measure and weather station warnings & alerts.

Disclaimer: Although "Palmy Weather" tries to provide accurate and reliable information, there may be inaccuracies. The weather forecast and information displayed on this website is a calculation based upon the data compiled from the local weather station.
This data is not intended for protection or preservation of life or property. Use discretion when making weather based decisions.
