April Temperature Last 14 Years Comparison

Since I had April’s data loaded into Google Gemini AI, here is the temperature summary for this year compared to the last 14 years.

By calculating the average of the daily mean temperatures (TEMP) recorded in the sources for each April, the years in Didsbury, Alberta, rank as follows from warmest to coolest:

  1. 2016: 8.5°C
  2. 2015: 6.0°C
  3. 2025: 5.5°C
  4. 2024: 5.4°C
  5. 2023: 4.9°C
  6. 2021: 4.8°C
  7. 2026: 4.6°C (Based on data through April 24)
  8. 2019: 4.6°C
  9. 2017: 3.9°C
  10. 2014: 3.7°C
  11. 2020: 2.2°C
  12. 2022: 1.8°C
  13. 2013: 1.4°C
  14. 2018: 0.6°C

Key Insights from the Mean Temperature Data

  • Warmest Year (2016): This year was significantly warmer than any other on record, largely due to a massive late-month heatwave where temperatures reached 29.7°C on April 19 and only dropped below freezing on 11 nights.
  • Coolest Year (2018): Despite having fewer total freezing nights than some other years (19 nights), 2018 was the coolest overall because of an extreme cold snap early in the month where daily mean temperatures were as low as -14.1°C.
  • 2026 Comparison: Through the first 24 days, 2026 is tracking very similarly to 2019 and 2021, which both saw a mix of early-month freezes and mid-to-late month warming.
  • Standard Cold Baselines: In the coolest years (2018, 2013, 2022, 2020), the low monthly mean temperature is driven by persistent daytime freezes (Max ? 0.0°C), which occurred between 4 and 9 times in those specific years

Windy Days

Last couple of days have seen some very high wind speeds, which seem higher than usage for this time of the year. My weather station as been recording data since August 2012, so I put all the April data into Google Gemini AI and had it figure out some wind stats. Here is what it came up with:

Based on the recorded wind gusts and daily average speeds, 2026 was the windiest year for the month of April in Didsbury, Alberta.

While both 2015 and 2026 share the record for the highest individual wind gust at 80.5 km/h, 2026 is the overall windiest due to its significantly higher sustained daily wind speeds.

Peak Wind Gusts by Year

The highest gusts (above 60 km/h) recorded during the April period are:

  • 2026: 80.5 km/h on April 24, with another major gust of 77.2 km/h on the 23rd.
  • 2015: 80.5 km/h on April 1.
  • 2013, 2014, and 2016: All recorded peak gusts of 69.2 km/h (April 20, 2013; April 8, 2014; and April 5, 2016).
  • 2020 and 2021: Both reached 62.8 km/h (April 25, 2020, and April 21, 2021).
  • 2019 and 2022: Both reached 61.2 km/h (April 17, 2019, and April 9, 2022).

Highest Sustained Wind Speeds

2026 stands out as having the most intense sustained wind activity. On April 24, 2026, the daily average wind speed reached 38.8 km/h, which is the highest recorded average in the dataset. Other years with notable daily average wind speeds include:

  • 2024: 24.8 km/h (April 17).
  • 2015: 23.5 km/h (April 1).
  • 2016: 23.0 km/h (April 9).

Consecutive Days of high Wind speeds over 60km/h

Based on the sources, 2026 is the only year in the recorded data that featured a consecutive multi-day streak of wind gusts exceeding 60 km/h.

While several other years had multiple days within the same month that reached this wind threshold, those events were always separated by days of calmer weather:

  • 2014: Recorded high gusts on April 8 (69.2 km/h) and April 11 (64.4 km/h), but they were separated by two days of lower wind speeds.
  • 2016: Had high gusts on April 5 (69.2 km/h) and April 9 (61.2 km/h), separated by three days.
  • 2026: In addition to the streak you mentioned, this year also had an earlier isolated high gust of 61.2 km/h on April 7.

The three-day streak in 2026 stands out as unique, with the following consecutive readings:

  • April 22: 61.2 km/h
  • April 23: 77.2 km/h
  • April 24: 80.5 km/h

So like my weather station console report, “Hold onto your hat”, it has been some very unique weather the last few days.

Cheers

Additional Home Page updates and testing new skycam

Some more adjustments to the main home page. Had been using RRSdog.com to pull the Environment Canada Weather Alerts, but they had some outages today, so AI and I tackled how to run it on my web server. Also updated the code to now show the new Environment Canada Weather colour codes when weather alerts happen. This will make it more noticeable when an alert happens.

A hardware change, I’m testing a new sky cam option. Had found out that the low cost (under $50) Wyze V3 cameras support RTSP connections. This allows me to run a script to pull an image off the camera and then upload it to the website. Most Wyze cameras only work with Wyze’s app. Not sure if the camera will survive Alberta winters. Will see if this becomes permanent. The original skycam (a Logitech webcam from 2012 running on Windows XP embedded) will continue to run and provide the webpage background image and backup if the Wyze camera fails.

Think I’m done the homepage modernization project for now. Let me know if anything glitches for you.
Enjoy the updates and happy weather watching!

Massive Weather Home Page Upgrade

For years, I’ve known there were issues with my weather station website’s layout, especially on mobile devices. I made several attempts to fix them but could never quite get things working the way I wanted.
With the help of AI, I was finally able to clean up the code and make significant improvements. Thanks to Google Gemini, the homepage is now far more mobile-friendly and responsive. Formatting issues have been resolved, and the layout now scales properly on larger displays.
I hope you enjoy the updates, and as always—happy weather watching!
Cheers, Jeff

Good Davis WX resource

Been doing some research lately and found this good resource for the Davis weather stations. So just saving the link here for future self.
Manual: https://www.manula.com/manuals/pws/davis-kb/1/en/topic/general-please-read

Some Notes
Interesting info on Barometer Pressure.
https://www.manula.com/manuals/pws/davis-kb/1/en/topic/pressure-reading-problems

The intrinsic accuracy of the barometric pressure readings for both Vue and VP2 stations is quoted as ±1mb or ±0.03“Hg and, once calibrated, most units will track other high-quality pressure readings in the locality pretty well and to within this nominal accuracy. There may be some long-term drift, in which case an occasional recalibration against a reference reading should fix any slight problem.

However, stations that are located at significant altitude (eg 1000-2000ft and above) may experience more frequent discrepancies against reference readings. This is not necessarily caused by any fault with the console but can arise because of the way that corrections are made from the measured local pressure back down to sea level. (The more elevated the location, the greater any sea-level correction will be, which is why this issue is usually only noticeable at stations located at significant altitude.)

When I compare my barometer readings to what Windy.com is showing for this area, my station is within 1mb. I do puzzle why so many other personal weather stations in the area are so different. Maybe they have drifted or not been calibrated correctly or is mine off. Since I cannot compare to an official calibrated one, I tried to calibrate mine to the airports in the area on a stable air pressure day.


Another topic of exploration was if I could move my UV and solar sensors to the anemometer mount point so they would never be in the shade. The sensor transmitter has plugs for UV and Solar, but found this text stating that it would not work.

https://www.manula.com/manuals/pws/davis-kb/1/en/topic/uv-sensor

Other transmitters: Users often notice that supplementary transmitters such as the 6332 Anemometer Transmitter or the 6372 or 6382 Temperature Stations use exactly the same transmitter board as the ISS, which therefore has sockets to connect solar or UV sensors. Regrettably you cannot use these supplementary solar/UV inputs. The reason is that solar/UV data must be received by the standard VP2 console as ISS data and the VP2 system allows only one ISS per station. (The supplementary stations will in fact transmit the solar/UV data, but this can only be received by eg an Envoy8X or Meteobridge Pro Red unit.)

Autumn Maintenance

Finally got around to replacing the 24 hour fan for the temperature sensor. Hoping these new batteries get the fan spinning properly again and my temperature readings become more accurate.
To replace them, I had to pull the full base station apart, so gave it a good clean. It had been many years since I gave it a full clean. Was showing it, so much dirt and spider webs.
Tried so hard to not bump the rain sensor, but right at the end, oops. 0.2mm measured.
Few photos of the dirty unit.

All clean and back together. Plastic is really deteriorating on the sensor cover and top of the temperature housing. Weather Station has been operation for 13 plus years now! The Oregon Scientific I had before this one deteriorated in 6 years and the plastic was so brittle, parts were breaking. Highly recommend the Davis Weather stations.

Replaced Batteries

Installed new backup lithium batteries both the anemometer transmitter and the main temp/rain/solar sensor transmitter.

Noticed the 24 hour Fan-Aspirated batteries are worn out and not keeping the fan running when lack of sunlight on the solar panel. On the repair todo list.

Data outage

Didsbury had a massive thunderstorm last night (June 28, 2024) around 2-3am. It knocked the power out for a second and ended up scrambling the weather console and network upload module. A full reset this morning got it working again.
I have a second console gathering the same data, so I was able to add the rainfall we got after the uploading console was put offline. Data I couldn’t upload are the daily max wind gust of 47km/h at 2:24am. We also had a max rain rate of 113.0mm/hr at 2:27.

First time I’ve had the weather console glitch like that.

False Rain – station cleaning

I was cleaning the spider webs and nests from the rain gauge and bumped the rain gauge and caused it to rain 0.4mm at 6pm today.

New Web Address!

www.didsburywx.ca

Well, I finally gave my personal weather site it’s own Internet address. For years the weather stuff was part of my side business BlueVistaVentures.ca. I had helped a few people build and configure personal weather stations and websites. Now that I’ve retired the business, it is time to clean up 16 years of linkage and systems.

What is with the address name? Well, the first bit is obvious, the town the weather station is in. Didsbury, Alberta, Canada. The WX is morse code shorthand for the word weather. So it is commonly used as the abbreviation for the word weather. So the address is translate to: DidsburyWeather.Canada
Not to be confused with the township of Didsbury, UK, which is now a suburban area of Manchester, England. Which Didsbury, Alberta is named after.

Please update your bookmarks to the new address. The existing weather.bluevistaventures.ca will continue for another year or so.

Happy weather watching! Cheers, Jeff
