Looking Northeast towards Vincent Thomas Bridge and Mt Wilson
Alas… Such a lonely post. Just waiting for the Tempest to ship. Am a bit concerned as the birds love the post. Hope they’re not as happy once the station is mounted.
The goats’ swing-set got a new Tempest! Nothing is too good for our goats…
I learned, like others, that PVC is too wobbly, but I had some 1/2" black pipe lying around, so I inserted that in the PVC. It’s not a super-tight fit, but I think it’ll do for the 4-5’ that the 10’ pipe projects above the swing-set.
Fail - I got false rain readings from some high-ish winds right after putting this up.
Is there a consensus on the best pipe to use - black pipe vs galvanized steel vs conduit? Is the smaller diameter of conduit a problem?
Use thick wall schedule 40 wall pipe, anything thinner seems to move too much. I went with the thicker pipe due to living on the gulf coast.
Schedule 40 is the minimum pvc pipe I would recommend. If you can find schedule 80, that’s even better. IMHO, no matter which type of pipe you use, it’s best not to install it on the playset, the vibrations will transmit and cause false readings. I would advise to use a 4X4 post that’s at least 2 feet into the ground.
Personally I find PVC is too flexible, steel appears to have a much higher modulus of flexibility which appears better for the haptic sensor.
Yes, my failed install uses schedule 80 PVC with 1/2" black pipe inside (which I had lying around), so I won’t use PVC again.
I don’t think the pvc and the black pipe is the root cause. Assuming you install the Tempest on a metal pipe that’s attached to the playset…The vibrations will continue to transmit to the pipe to the Tempest. The vibrations from the playset is the weak link or root cause.
I’ve got my Tempest mounted to a schedule 40 pvc pipe that’s mounted to a 4X4 post. So far, I’ve had very few false rain readings. I’m good with accepting risks because the cost and effort for a professional mounting set-up is beyond my interest.
I’ve got my Tempest mounted to a schedule 40 pvc pipe that’s mounted to a 4X4 post.
I’m curious why you used both the 4x4 post, and pvc pipe. Was it just to get additional elevation? They show this in the example installations as well.
I’ve got about 7 foot of exposed 4x4 in a very open area and don’t see any need at this point to go higher, so I plan to mount with the screw head on top of the 4x4.
You’re correct. It was to get additional elevation above the fence line so all the solar panels could receive sunlight.
Received one of my Tempests and installed it at Raleigh’s Place in Clanton, AL. I know it’s not an ideal installation for temperature readings but it was the best location for wind readings. But I do have several questions:
I was trying to find information about the calculation that WF will apply to the Tempest stations that will allow the passive shield to operate as if its fan aspirated. Where can I find it?
How do I know if CL has performed calibrations to your Tempest station?
Do you set the elevation to where your HUB is located or where the instruments is sited?
If your dirty hand touched the solar sensors/haptic rain sensor, would the dirt and skin oil affect the solar sensors?
Why is my SLP is reading .04-.05” too high and the UV reading around 3-5 too low during the day?

I’m in the same boat as you, waiting for my Tempest to ship. I have mounted my PVC pole to the deck and made a bird spike to hopefully train the birds NOT to land on it.
Is your Bird Spike just a “training tool” for the birds. . .or will it actually be incorporated with Tempest? Where will be spiked cap be placed in relation to Tempest?
Yes, I’m calling it a “training tool”. Since I don’t have my Tempest yet, I didn’t want birds to start landing on the empty pole that I have already set up (and then start landing on the Tempest once it’s installed).
I picked up a 1 inch PVC cap from Lowes that fits over the end of my PVC pipe and super glued nails to it. The cap fits over the end of the pipe (as shown in the photo) so that birds will not get used to landing on the pole before the Tempest gets mounted. I have heard that WeatherFlow has developed a “Crown of Thorns” type bird spike system that should be available for purchase soon. I will be purchasing one when they are available.
The WeatherFlow Bird Spike system is mentioned in the following post:
Yes the “Crown-O-Thorns” idea was mentioned quite some time ago. . .but they (WF) has been SO busy with Tempest lately. . .that Crown-O-Thorns hasn’t been mentioned recently. Keep tuned to the Community Forum (Owners Category) page — it will appear there when they announce it. I am interested in 3 of them — 1 for WFSKY-01 and 2 for Tempests [one field test unit and one for actual production Tempest].
I thought I had read somewhere that they might be available in the July timeframe. If not, that’s too bad. After seeing how well my end cap version came out, I might have to try to make my own.
Any assistance or advice is greatly appreciated. I don’t necessarily want to move the Tempest station but will do if you think it’s necessary.
You set it to ground level.
