I'm in 1-2. Would like about 4, I want to see 100 in at least 80% of years.

[FirebirdCamaro1220]

I'm in the 50-153 group. Our normal high is 100+ from June 3rd-September 15th, which is 105 days

[Steelernation71]

I'm in the 0 group. Haven't hit 100 in 80 years and probably won't for a long time. I'd prefer to be in the 5-10 zone (I'd like about 7 a year).

Seattle has had 2 days of 100+ since 1981. One in 1994 and one in 2009.

I'm in zero and I'm happy for that. Who needs 100F. Serves no useful purpose for outdoor activities, gardening, agriculture, etc

[Botev1912]

I agree. I was outside on that 29 July 2009 day when it recorded the all-time high of 103 and it was terrible.

Number of times 100°F has been hit this year so far

Thanks for the cool pictures. Here in the desert, our concern is less with how many 100 degree days we have to deal with and how many 110 degree days we have to deal with. The average (1981-2010) is 19 days a year of 110 or greater for the high temperature. For us at least, those seem to be the days that you really notice the heat as being exceptional. This time of year for us to get a day at or below 100, it is usually going to be a day with high humidity and a lot of cloud cover. Those are my favorite summer days mostly because they tend to happen immediately after a day with a lot of convective activity and storminess.

Two things, for now:

1.) 100F days seem to be much less frequent on the Texas coast than one would commonly think, given how much the state is associated with long droughts and high heat; the northern coast, in particular, is in the same range as parts of the Florida Panhandle, as well as small sections of the South Atlantic Coast. If you dig deeper, you find that within the same time period, Savannah, GA recorded 100F temps more frequently than central Houston, and Brownsville. And all that is even with a major heat skew, in the form of the epic 2011 drought (worst in centuries for Texas), being taken into the average:

2.) 100F days seem oddly frequent on the Yucatan Peninsula; the numbers recorded match up with many areas in the southern/central US plains.
