This sounds like a heat rash or milaria , though nothing can be said with surety without having a look at the lesions. This could also be cholinergic urticaria.
'Miliaria (miliaria rubra, sweat rash or prickly heat) is a skin disease marked by small and itchy rashes. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer season. '
'The prevention and treatment of miliaria primarily consists of controlling heat and humidity so that sweating is not stimulated. Measures may involve treating a febrile illness; removing occlusive clothing; limiting activity; providing air conditioning; or, as a last resort, having the patient move to a cooler climate.'
