Bahia Kino, Sonora - how cold is it really?

I don't know where some of those sites get their information. I use qwikccast.com or accuweather. Often they forecast rain and we know it is not going to rain. Hermosillo is getting some cold temps. About 5 C overnight. Today it is 70 outside but the forecast was for 67. Overnight has been high 50's. We could have had Christmas dinner outside as it was 73 in the afternoon But it has been windy. Not a cloud in the sky. You have to go further south than Maz for really warm weather.
