SINGAPORE – The tropical heat and humidity will be a cause for concern for the elite triathletes who will be racing at the Singapore T100 – which was previously known as the Professional Triathletes Organisation Asian Open – on April 13 and 14.

Despite rainy weather on several days, late March and parts of April saw daily maximum temperatures here reach close to 35 deg C. Experts forecast that temperatures in April and May – regularly the year’s warmest months – might rise higher, owing to the lingering effects of El Nino.
