I was happy to be able to ride to work in Israel for about a year. Every single day (I think I skipped maybe 3-4 days due to not feeling well or bad weather, but I did use a bike on days where the Israeli streets were flooded so high, that my lower pedals were submerged at times).
Temperature was usually nice - even Winter's a joke and rarely reaches 0 - mostly it's about 8-10 degrees (C). Summer can reach 32, 34 degrees (C) and on those days even early morning rides are a bit taxing.
We had a shower in the office though. Little cabin. Takes ~no~ space. Since I've been there, I think that every office should have one.
