I just ask as I've noticed my temperature is higher than it usually is recently in the afternoon.
I keep forgetting to do it properly in the morning - but my afternoon readings (always after having sit down for a while etc) are around 36-37 when they've always been about 35.
I'm wondering if this signals anything, and why it wouldn't?

Not sure about why your temperature is higher than normal in the afternoon just now but you don't actually have to temp in the morning - it's your basal body temperature that you need for tracking ovulation which is your body's lowest temperature attained during rest. You need to have been fully at rest for ideally 3+ hours and that's why it's recommended to take your temp in the morning after sleeping as that's when most people are fully at rest for a long period. But shift workers can't always take their temp at the same time each day so as long as its taken after a long rest period it should be fairly accurate. Tbh it doesn't really matter what your actual temp is as long as you can see a thermal shift after ovulation that's all that's really important. How long are you resting for before taking your temp in the afternoons? Temperatures can really fluctuate throughout the day, it's only the basal body temp that's most accurate. Hth!

It is all to do with our circadian rhythm. Each day we go through cycles that each trigger another event, and the result is a nice, predictable pattern of when we wake, sleep, feel hungry, go for a poo etc.
Our temperature is lowest during the early hours of the morning and highest early evening. However, our daily activities and stress levels can affect how high our temperature is at various times of day. The lowest temperature remains quite uniform, which is why you can monitor it and know the changes in basal body temp (lowest temp) are due to hormone changes after ovulation.

I've been wondering this too because I started temping this week and really don't want to be setting an alarm at the weekends

Thanks all. Really helpful.

Apparently in order to get a true basal body temp reading it would need to be taken while you actually are asleep, which is why they say to take it immediately upon waking and before moving around, even to sit up, and it's best if you're still half asleep.
Of course, this means that the couple times I've randomly woken up at 2am this month I've automatically taken my temp, only to then realise the time and grumpily go back to sleep only to wake up 5 hours later to take the temp again!
