Summary

Temperature, Humidity, and Barometric Pressure Data

The colored graphs and values represent the current value, maximum, and minimum, including the time when measured, resetting at midnight. The arrow over the current value indicates whether it is rising, falling, or steady.

Outdoors temperature:  As tracked for the last week, in Fahrenheit degrees.
Indoors temp / Outdoors temp: As tracked for the last 24 hours (indoors uses the white line and the scale on the left in the graph, outdoors is the yellow line, and uses the scale on the right; both in degrees-F).  Note: We heat our home exclusively with a wood stove, and don't have central heating or air conditioning.  As a result, the temperatures inside sometimes swing fairly widely.

Barometer / Humidity: Combined barometric and humidity graph, with the barometric reading the shaded white area (hPa or mm) and the humidity (%) reading using the green line, both tracked for the last week.
Humidity: The humidity in percent, as measured over the last 48 hours.

Sea level barometer: Barometric pressure over the last 48 hours, measured in hPa, compensated for sea level altitude.
Dew point:  Dew point, the temperature (degrees-F) at which moisture will condense in clear air, as measured over the last week.

Wind Statistics

All measurements in miles-per-hour (mph).  The wind run graph measures the total volume of wind on a given day, as measured for the last week. The wind direction graph shows how much wind came from each of the compass directions during the last 24 hours.

Rainfall

24 hour rain:  Total rain during the last 24 hours, in inches.
Daily rain:  Total rain since midnight.
Rain Rate:  Current rainfall rate, in inches/hour.
Total rain/year:  Rainfall totals, measured in inches, are calculated from July 1st to June 30th each calendar year. Average total rainfall in Boulder Creek during a typical rainy season, from November to April, is 40-60 inches, although this can vary considerably.  For the 2004/2005 rainfall season, click HERE.

Daily rain:  Total accumulated rainfall during any given day, in inches, with the amount reset back to zero at midnight.
Hourly rain:  Total accumulated rain during each hour, in inches.  This one is most useful for seeing how heavy the rain has been; high numbers during a short period of time usually means a downpour, while low numbers spread out over time will typically indicate steady showers.

About this Weather Data

The Weather Station

The weather conditions and data reported on this website are collected by our Oregon Scientific weather station, with wireless sensors places on and around our home.  The instruments include sensors for temperature (both indoor and outdoor), humidity (indoor and outdoor), barometric pressure, rainfall, and wind speed and direction—and they're all wireless, sending their information back to a base unit that operates with either AC or battery power.  This data can then be sent via a serial line to a computer.

I'm not sure how long the link will remain active, but Oregon Scientific still sells the model, the WMR968, info available here.

The Software

We are currently using a product called "Weather View 32, Professional Edition."  Cost a bunch, but it's what produces all those pretty graphs and which allows us to upload the data to this website.  Info available here.

The data on this page is updated on the website every 15-20 minutes (may be interrupted by disruptions in Internet connectivity, power outages, etc.)

The Location

Our home is located east of Boulder Creek proper, near the top of a ridge (1100ft altitude, compared to BC's 630ft).  The coordinates are 37 degrees 6.902 minutes north, by 122 degrees 6.227 minutes west.  Due to the specific placement of our house and the sensors on it, our readings are sometimes different than that reported by another of the stations nearby (click here to go there; terrific website, too).

I should also add that one of the charming—and occasionally maddening—aspects of this region of the country is that it truly is the land of microclimates.  In less than a five minute drive, you can experience variations in the local weather conditions.  Drive twenty minutes (say, over to Davenport or down to Santa Cruz), and the current weather is likely to be completely different.  For instance, it's not uncommon for the shore to be socked in with fog, while we up in the hills roast under 90+ degree temperatures.  Or for the higher elevations to get inches of rain, while the valleys a short distance away see only a trace.  On very rare occasions, we're even high enough to get a little snow.

Comparing our readings with that of other local weather stations, I can say with some certainty that our anemometer (wind gauge) registers lower than the prevailing local speed.  The reason for this is because our home is in the lee of the nearby ridge, and deep in a heavy section of redwoods.  In addition, there is occasionally a bump in the evening outdoor temperature readings, because the warm air from the valley below will rise in those early post-sunset hours (we've seen variants as big as 20F, and in the winter, the valley is almost always colder than we are).  Further, we do usually receive more rain than other stations might report, again because of our location and altitude.

Finally, in case you were wondering, that name at the top of the page, Serenity, is what we call our home.  Long story.
