Ben Khoo got analyse marathon timing diff for Singapore vs other cool climates previously
Singapore T100 is also basically one of the slowest, heck.....it IS the slowest out there. Based on the pro timings.
Quite significant also, off the back of my hand it's ~ 10 mins range.
Yes got places like Qatar and Dubai but then that's during their cooler months which also have very low RH%. Really need to look at the heat index temperature.
Then SG T100 is during April, which if one is into local meteorology, is when we have the %#$#$ highest temps and RH% no thanks to intermonsoon season. (no, our warmest months are not in June/July but it aint that far off to be fair). We have another intermonsoon season when we transition from SW to NE monsoon but that one usually not as hot.
And of coz, they juuussst gotta start at 2pm and 3pm for Pro women and men , coz LLST got the age group races in the morning. The only silver lining is that for the run leg, 5pm+ for women and men, a wee bit "cooler", but then the bike leg would still be terok. I think they might have constraints shifitng 3 hours later and doing evening + night racing.
Actually, just quick AI check ba....
Singapore experiences its highest heat index (or "real feel" temperature) during the inter-monsoon months of
April and May, with high heat stress conditions frequently extending into June and October. Afternoon temperatures often peak between 3 pm and 6 pm, with high humidity and intense solar radiation causing heat index values to exceed on extreme days
Key facts about high heat in Singapore:
- Peak Months: April and May are historically the warmest months. In 2023, high heat stress days occurred mostly in April, May, June, and October.
- Highest Temperature:The highest daily maximum temperature ever recorded in Singapore is
, recorded on 17 April 1983 and again on 13 May 2023.
- Factors: The high heat index is driven by high humidity, light winds, and intense sunshine between the Northeast and Southwest monsoon seasons.
- Daily Peaks: The highest heat index typically occurs in the afternoon (12 pm – 4 pm).
