# Weather, Waves, Tides






In this site we present nowcasts and forecasts of weather, waves, and tides at various locations around New Zealand, with a particular concentration on Canterbury where we live.

The data come from various sources including GeoNet, GFS, Australian Bureau of Meteorology, and personal weather stations (PWS) at Port Levy, and Riccarton/Hagley.

The sites are updated daily.

There is also a section on earthquakes measured by local seismometers including our own RaspberryShake, a miniature seismometer that measures vertical ground motion. It was developed by a Panama/Germany team as described here.

These webpages are running on a Raspberry Pi, a credit-card sized computer that was developed as a dirt-cheap (US$35) machine for educational purposes, but is also used by hobbyists. More than 10 million units have been sold.

The Raspberry Pi also does the data processing using a variety of programs including Java, Fortran, Octave, gnuplot, and numerous Linux commands (awk, sed, etc).
