I haven’t found yet an outdoor cheap BLE temperature sensor with a suitable radiation shield (you need shadow if you want a proper measurement, and the shield provides it).
If you are keen to assemble something you could use a waterproof one like the IBS TH2 IPX4 in an enclosure with air circulation or buy the shield separately.

You would have more choices and more range with 433mhz temperature sensors (requires rtl sdr or an esp32 lilygo/heltec v2.1)
