After struggling on yesterday`s ride and failing to complete what I intended for the first time this year due to the heat (partly my fault, as I didn`t appreciate quite how hot it was so didn`t go with my coolest possible top options as it means no pockets), I was searching for info on how humidity and heat combine. I came across this thing called the heat index, which for those who don`t know, factors the humidity in with the heat to create a more accurate representation of the actual heat.
from Wikipedia
`The heat index (HI) is an index that combines air temperature and relative humidity in an attempt to determine the human-perceived equivalent temperature`

so basically, given a temperature of 31C and 70-75 humidity, I was trying to do L4 intervals at around 95-100F (Sunstroke, heat cramps and heat exhaustion possible) Oops. Looks like I will have to adjust plans and settle for summer base phase.
edit: These sites allow you to work out the relative temperature:-

Be careful out there!
